Endodontic access cavity: the Dilemma of conservatory approach

Hafsa El Merini (Morocco)

The 1st step in endodontic therapy is endodontic access cavity (EAC ). It consists to open the endodontic space by crossing the roof of the pulp chamber.
The adequate realization of the access cavity implies good knowledge of endodontic anatomy, a careful assessment of pre-treatment radiographs, a staging of the spatial location of the pulp chamber and an understanding of the pulp pathophysiology which leads to the reduction of the pulp volume. The EAC will make it possible to determine the number of root canal entrances, then will allow the passage of the instruments in the canals in order to ensure their cleaning, disinfection and shaping before obturation.
For a long time, endodontic access and endodontic treatments have been linked to the loss of tooth’s strength. Today, it is clearly established that the weakening of the tooth is more related to the loss of marginal structures and occlusion beams than to the access cavity itself. However, to face concerns about tissue’s conservation, the endodontic access cavity had been slightly modified and shifted from conventional EAC to conservative and even to ultra-conservative EAC.
Often the clinician is faced with this dilemma between tissue preservation and access to the canal.
The aim of this work is to define the indications and conditions for the realization of « conservative endodontic access cavities ».

New insights in root canal irrigation : Are we able to eradicate all bacteria?

Carla ZOGHEIB (Lebanon)

The main goal of any endodontic treatment is to eliminate the microorganisms that colonize the root canal system. This disinfection is mainly based on a chemo-mechanical preparation where the limits of the endodontic instruments, which shape the main canal, are palliated by the irrigating solutions. Effective active irrigation is therefore an essential step to the success of endodontic treatment. Studies are currently undergone to validate Sonic/Ultrasonic or Laser activated irrigation (LAI) as innovative and efficient technologies in modern endodontics.
Our presentation will provide an overview of the technologies currently available to improve the effectiveness of endodontic irrigation solutions. Several activation systems will be presented: from manual dynamic with gutta-percha cones, to sonic or ultrasonic systems and finally to laser-activated disinfection. It is therefore clear that the activation of different irrigation solutions would offer several advantages in the clinical endodontic outcome and that the integration of new technologies would contribute to an improvement of the quality of care in daily clinical practice.

The Story of HEDP in Endodontics

Matthias Zehnder (Switzerland)

This lecture will focus on how to render chemical root canal debridement simple and effective. It has become clear over the years that NaOCl is the core chemical to be used for that purpose. Delivered in an endodontic irrigant, NaOCl uniquely dissolves biofilm and necrotic soft tissue remnants. Furthermore, it can bleach blood-derived stains in dentin. What NaOCl does not do, however, is to prevent “dentin mud” or, more precisely, inorganic debris and smear layer from accumulating during mechanical root canal preparation. NaOCl does not condition the root canal wall for optimal sealer adhesion either. To this end, decalcifying agents are necessary. Traditionally, EDTA or citric acid solutions were used to dissolve smear layer and accumulated hard tissue debris. In this lecture, it will be discussed why a molecule used in the cosmetics and dishwashing industry, namely 1-hydroxyethane 1,1-diphosphonic acid (HEDP), could be advantageous also in endodontics.

Current and future scope of bioactive materials in endodontics.

Josette Camilleri (United Kingdom)

Materials used for endodontic therapy were developed with the scope of creating a hermetic seal that prevents microbial re-entry and sealed off any remaining microorganisms inside the root canal. The development of mineral trioxide aggregate (MTA) for sealing root perforations and root-end filler introduced a new type of materials in endodontics. MTA and the second generation materials developed from it have specific properties. They are hydraulic thus develop their properties in a wet environment. Furthermore, they are very reactive and interact with the environment where they are placed. This specific property led to the development of materials for various uses in endodontics. The scope of this lecture is to go over the material properties, material development and the specific clinical applications of bioactive endodontic cements.

New strategies to improve the efficiency of root canal irrigation

Hussain Al-Huwaizi (Iraq)

The trend in research in endodontics has shifted towards root canal irrigation. This step in root canal therapy is vital to offer a clean and biologically inert space to be obturated later. There are many parameters that govern root canal irrigation which are imperative to ut;ize to get a debris free root canal such as the type and protocol of irrigation and method of irrigant agitation.

This lecture is based on the new researches performed by the postgraduate students in the college of dentistry, university of Baghdad, Iraq which are published in the international journals.

Smooth management of complex root canal therapy: The importance of Ultrasonics.

Marc HABIB (Lebanon)

The root canal treatment difficulty is related to the endodontic complexities encountered in anatomical variations. That is usually noticed in rare and difficult root canal configuration. Sometimes to this anatomical aspect will be added pathological or iatrogenic obstacles that will make the root canal therapy even more challenging to achieve. Obstacles could be calcifications like pulp stones, inexistent pulp chamber space, missed anatomy or secondary treatment of previously treated teeth with metallic or carbon fiber obstruction. For these special cases the clinician should be armed with specific tools like ultrasonic tips, magnification and experience to be able to face the demanding case at hand. In this presentation, we will highlight anatomical variations with specific added obstacles. Cases of screw posts, broken instruments, silver points, fiber post removal will be managed as well as missed canals retreatments. The aim here is to underline the importance of visibility while dealing with such treatments that can’t be achieved without the help of ultrasonics and microscopy.

The Natural Tooth Is The Best Implant. Who makes the Clinical Decision? Endodontic Prospective

Jamal M. El Swiah (Libya)

Advances in endodontic therapy and endosseous implant technology have a significant impact on the treatment plan decision making in modern dentistry. Furthermore technically implant and endodontic therapy is the most rapidly changing subject in recent years in the field of modern clinical dentistry and is very increasingly being practiced by general dentists and specialists alike. Therefore one of the major issues most frequently confronting the contemporary dental clinicians is the clinical decision dilemma between preserving a questionable natural tooth by endodontic therapy or extracting it with placement of a dental implant. As the major studies published up to date shows no difference in the long-term prognosis between single-tooth implants and restored endodontically treated tooth, there is an absence of professional consensus between dental clinicians regarding correct selection criteria of one procedure over the other for each particular case. Therefore the lecture will look at the available general considerations from literature to delineate some useful information on this subject to help the dental clinician make a proper decision when faced with such situation. Furthermore the lecture will be illustrated with cases of clinical examples from the speaker’s own case book.

Shaping difficult root canals with confidence and predictability.

Pr Pierre Machtou, DDS, MS, PhD, FICD

Since the introduction of nickel-titanium for machining endodontic instruments, mechanized shaping is now mainly taught in dental schools (Koch Eriksson et al., 2009) and routinely used by both general practitioners and specialists (Bird Chambers et al. 2009).

As a result, many NiTi shaping systems in continuous rotation or in reciprocation are available and thank to the new thermal treatments of the NiTi alloy, safety has been improved, indications have been expanded and shaping has never been so versatile. Nevertheless, specific strategies are required and must be implemented for the management of difficult root canal anatomy included long, narrow, s-curved canals and apical hooks. In these situations, even with utmost careful attention the slightest mistake can lead to a difficult and often irreversible situation. Canal blockage and/or transportation can occur as early as the initial negotiation step and may compromise the treatment outcome.

This presentation will discuss the causes of these mishaps, the way to avoid them but when present, provides the clinical solutions to treat them.

Aims


The aim of this lecture is:

  • to provide a precise protocol to consistently get a smooth and uneventful flow of the instrumentation process during the cleaning and shaping procedure
  • to identify the mishaps that may occur during cleaning and shaping of difficult canals, how to avoid them and provides the clinical tips to fix them

Objectives

  • To provide a step by step protocol during all phases of the root canal shaping
  • To emphasize the clinical procedures needed for managing sharp apical curvature
  • To analyze the factors involved in mishaps

The role of irrigation in root canal treatment

Irrigation combined with instrumentation is an essential part of the root canal treatment. The aim of the shaping procedure is to create space to irrigant delivery to clean and disinfect the root canal system and then to filling materials placement. The ultimate goal is to eliminate debris and bacteria from the root canal system to expect predictable success. However, research has shown that complete debridement is impossible to achieve with the syringe delivery of irrigants (static irrigation). Indeed, the apical region and the intricacies of complex root canal systems are the most difficult areas to clean with this traditional method. Currently, activation of irrigants (dynamic irrigation) at the end of the cleaning and shaping procedure is advocated to help distribute irrigants into these restricted areas. The objective of this presentation is to review the different irrigating solutions and protocols including the current methods of irrigant activation, assess their pros and cons and consider potential developments for the future.

At the end of the presentation, the participants must:

  • be able to assess the benefits and limitations of the main irrigants used in clinical practice
  • be able to know the limitations of syringe delivery and how to improve it
  • be able to know and assess the pros and cons of the current methods of irrigant activation

Urgences médicales dans la pratique odontostomatologique.

Pr Mohammed Mouhaoui

L'odontologie est une activité potentiellement à risque car elle a souvent recours à des actes invasifs (anesthésie, incisions, lambeaux...). Le médecin dentiste est un professionnel de santé et, à ce titre, doit être capable de prendre en charge une situation d'urgence médicale survenant dans son cabinet. Cependant, il n'est pas un professionnel de l'urgence médicale et ne rencontre pas ce type de situations quotidiennement.

Devant une situation d’urgence, le médecin dentiste n’est pas censé établir un diagnostic précis, mais plutôt savoir détecter les signes d'alerte et dispenser les premiers soins dans l'attente d'une équipe médicale d'urgence. Pour cela, le médecin dentiste doit être capable à terme d’identifier, d’évaluer et de décrire une telle situation. Il doit aussi avoir des capacités dans la mise en œuvre rapide des gestes et des attitudes adaptée. Enfin, il doit posséder et maîtriser le matériel et les médicaments nécessaires à une prise en charge efficace du patient.

Cet atelier se veut une initiation pour guider le médecin dentiste dans la gestion des situations d’urgence médicale qu’il peut rencontrer dans son cabinet, tout en utilisant des techniques non ou très peu invasives. Il ne doit pas se substituer à une formation pratique sur le terrain, mais peut en être un grand support.

Evidences of Files Selection for Efficient Application in Daily Practice.

Hyeon-Cheol Henry Kim (south Korea)

Endodontic treatment is mainly purposed to reduce/remove microorganisms and infected tissue from the root canal system. To reach this goal, clinicians may need to keep the principles from the diagnostic procedures to post-endodontic restoration based on the rationale of endodontics. It is absolutely important to have knowledge on modern endodontic methods and concepts including contemporary materials, through which we can maintain a high success rate of treatments.
Among the contemporary endodontic materials, nickel-titanium (NiTi) endodontic files have brought a big step toward “efficient” practice of endodontic procedure. The NiTi files help clinicians not only reduce their working time but also increase the clinical success rate with minimal procedural errors. Especially, recently introduced instruments made of heat treated alloy in various designs made it possible to shape the root canals with minimal number of instruments and to preserve the root dentin integrity.
Clinicians need to understand the characteristics of each instrument system and its mechanical properties as well as the basic principle of root canal shaping. This lecture will give an insight based on research evidences for the selection of endodontic instruments with minimal risk of fracture as well as root dentin preservation.

How laser induced bubbles change endodontic cleaning and disinfection approaches: everything you need to know.

Roeland De Moor (Belgium)

Since the beginning of this century, an evolution in the application of endodontic irrigation solutions has taken place. Different devices to activate irrigants have been proposed and marketed. Protocols for activation of endodontic irrigants were launched and investigated. There is the general sense that increased agitation of irrigants inevitably results in better root canal cleaning and disinfection. In a recent, not yet published systematic review, we came to the conclusion that it is almost impossible to compare the efficacy of sonic versus ultrasonic irrigation, taking into account recommended inclusion/exclusion criteria.
Studies on Laser-Activated Irrigation (LAI) based on erbium laser induced cavitation demonstrate the superiority over conventional approaches (sonically and ultrasonically activated irrigation). With more in-depth investigations on fluid streaming the working mechanism of all these systems became clear. Apparently there is a difference in the level of acoustic streaming and in the type and impact of cavitation.
During this presentation insight is given in the working mechanism and efficacy of irrigant agitation techniques, and we show how flow matters supported by high speed images.

Endodontic failures: How to prevent them? How to solve them?

Hédia Ben Ghenaia Jaouadi (Tunisia)

Comme toute intervention chirurgicale, le traitement endodontique peut amener à un échec à court, à moyen ou à long terme. L'échec endodontique peut avoir des étiologies différentes et complexes qui dépendent essentiellement de chaque étape du traitement endodontique. Il est souvent la conséquence d'un diagnostic erroné, d'une anatomie endodontique complexe, du non respect des règles d'asepsie et d'antisepsie, d’une préparation ou d’une obturation canalaire insuffisante, d'autres facteurs liés au patient et au praticien.
Comprendre la différence entre toutes ces situations est essentiel afin de poser le bon diagnostic d’échec et de mettre en place la thérapeutique adéquate.
Notre travail a pour objectif de détailler, à travers des cas cliniques, les différentes difficultés auxquels le praticien peut être confronté lors du traitement endodontique et la conduite à tenir afin d’aboutir au succès thérapeutique.

Dental Trauma Updates.

Zuheir AL KHATIB (UAE)

Patients with trauma to the dentoalveolar apparatus might be referred to an endodontist for treatment and urgent care.
The treatment plan and decision-making process will depend on many factors including but limited to patient’s age, degree of trauma and the stage of tooth development.
Therefore, mutual understanding and knowledge of protocols and guidelines in managing dental trauma cases is required. Endodontic, IADT and Pedodontic Associations around the world are actively publishing and updating their guidelines and protocols to treat and manage cases with trauma.
Our aims to provide the dental community with the latest updates on these guidelines and protocols. Finally, cases and their management will be presented and discussed.

Vital Pulp Therapy as an Alternative to Root Canal Treatment: Dream or Reality?

Dan-Krister Rechenberg (Switzerland)

In the vast majority of cases, microbial challenge is the main cause for a pulp to become inflamed. Historically, severe pulpal and periapical inflammation was treated by extraction of the affected tooth. However, because of the increasing understanding of fundamental biological principals and technical advances, the concept of chemo-mechanical root canal disinfection was introduced in the early days of the last century. Thousands of teeth could be preserved, which would otherwise have had to be removed. Nevertheless, conventional root canal treatment (pulpectomy) frequently is an overtreatment, especially in cases with minor inflammation restricted to the coronal part of the pulp. This may be a disadvantage, especially when considering that vital pulpal tissue shows efficient protective mechanisms, and great healing capacities. The aims of ‘new age dentistry’ involve prevention of disease, minimal invasive therapies, and regenerative procedures. In this context, and particularly considering recent advances in biomaterials, vital pulp therapy must be re-evaluated. The success of this approach greatly depends on i) the absence of microorganisms, and ii) the pulpal immunocompetence/absence of inflammation. Unfortunately, both aspects cannot be reliably determined clinically. Current diagnostic regimes neither reflect the actual stage of pulpal inflammation accurately, nor do they reliably predict the chance for pulpal survival after (vital pulp) treatment. One cornerstone for the success of these approaches could be improved pulpal diagnostics.

The aim of this lecture is a critical appraisal of the advantages and limitations of current vital pulp therapy concepts in comparison to conventional root canal treatment. A further goal is to describe future concepts for endodontic diagnostics, and how these could complement vital pulp therapy.

- To provide an outline on vital pulp therapies in the framework of current treatment concepts
- To analyze the factors that determine the success/failure of vital pulp therapy
- To envisage the potential of an improved, more biologically based endodontic diagnostics for vital pulp therapy.

Root canal irrigation: Blending Endodontics and Fluid Dynamics.

Christos Boutsioukis (Netherland)

Irrigation of the root canal is an essential step during endodontic treatment. For many decades studies on the antimicrobial and tissue-dissolving properties of irrigants dominated the relevant literature. More recently attention has been also focused on irrigant delivery and agitation, in order to bring the irrigant into closer contact with microbes and tissue remnants. Several well-established experimental and computational methods from the fields of Engineering, Physics, and especially Fluid Dynamics have been employed in a multidisciplinary effort to gain insight into the mechanisms involved. This lecture will attempt to bridge the gap between Endodontics and Fluid Dynamics and discuss the irrigant flow developed inside the root canal system during delivery and agitation. In addition, issues such as irrigant penetration and refreshment, entrapment of air bubbles, turbulence, the effect on the root canal wall and the pressure balance at the apical foramen will be addressed.

Management of Experimental Endodontic Perforation of Dog’s Teeth.

Saad Abdulaziz Al-Nazhan (Saudi Arabia)

Lateral, furcation and apical perforations are undesirable incidents that may occur during any stage of endodontic treatment, post space preparation and defects caused by resorptive processes or caries. Surgical or non-surgical approaches can be done to treat the defect aiming to preserve the tooth. Different materials have been used to seal the perforated site. The criteria for an ideal repair material include sealability, biocompatibility, insolubility and ability to induce osteogenesis and cementogenesis. A more recent paradigm shift from traditional endodontic treatment to regenerative endodontic therapy is further revolutionized by the introduction of blood clot and Platelet-rich plasma. This presentation will discuss the repair of endodontic perforation defect of experimentally perforated dog’s teeth using MTA and Platelet-rich plasma.

Ultrasonic tools and tactics for successful retreatments.

Walid Nehme (Lebanon)

Root canal retreatment is a challenge with various level of difficulty dictated by previous filling materials or mishaps. These factors might hinder the clinician from achieving a thorough cleaning and shaping of the whole canal system and can make retreatment a stressful and time-consuming procedure.

In this presentation, the use of ultrasonics will be reviewed during the various phases of retreatment, which will allow the clinician to conclude a successful outcome. A didactical description of clinical procedures used for a swift coronal disassembly, a predictable approach for missed canals localization, a safe strategy for the removal of solvable and solid root filling materials. Multiple representative clinical cases will be reviewed for discussion.

conclusion, participants should be able to:

  • Acknowledge the importance of ultrasonics in the different phases of non-surgical retreatment.
  • Choose the appropriate ultrasonic tip and technique for coronal disassembly, canal exploration and removal of different root canal pastes, carriers, separated instruments and silver points.
  • Evaluate the risks and prognosis of each treatment option.

Saving the hopeless tooth: Is it hopeless?.

Mehmet Baybora Kayahan (Turkey)

The aim of endodontic treatment is to prevent or cure apical periodontitis. Root canal treatment is a predictable procedure with high survival rate. However, procedural problems such as ledge formation, transportation of the canal, root perforation and extrusion of the irrigants can affect the prognosis. Today, patients demand the retention of their teeth more than ever before and this results in increasing necessity for retreatment. The success rate of retreatment is over 80%. There is no doubt that both root canal treatment or retreatment of teeth are feasible and economical way to preserve function. Nevertheless, when a previously root canal treated tooth fails or the final radiograph of the retreated tooth is not satisfactory, some practitioners are quick to call for extraction. In this lecture, follow-up of some tricky cases will be presented and discussed from another point of view.

Minimal Invasive Endodontics: new paradigm or fad?

Ana Arias (Spain)

Scientific literature has demonstrated that the most common reason for tooth extraction is vertical root fracture. It seems to be a fracture predilection for restored endodontically treated teeth. At the same time, we are living the moment of minimally invasive dentistry and this concept should also apply to root canal treatments. Ideally, removing the less dentine as possible should be desired to maintain tooth strength. Manufacturers, in combination with researchers and clinicians, are working together aiming to achieve instrumentsthat allow the adequate disinfection of the root canal system minimizing the removal of dentin that relentlessly leads to the weakness of the tooth. Although, with the increase in life expectancy and emergency of implants, we also have further responsibility: performing a good prognosis assessment to determine the viability of the entire complex considering patient characteristics. This will allow to decide if a particulartooth would be successfully preserved and to enhance the concept of endodontics among other dental specialties and our patients. In this lecture, case series will be combined withscientific evidence to set some basis to help in making the proper decision.

Clinical tips for a safe journey from severely curved lines to a well cleaned and shaped space.

Ahmed Madarati (United Kingdom)

Proper and effective cleaning and shaping of the root canal system has been considered as one essential step towards more successful root canal treatments. While this can be a straightforward step in many cases, it may be an extremely challenging procedure in others. Many procedural mishaps can be encountered when instrumenting severely curved canals, especially S-shape ones, such as ledges formation, root canals perforations, canals blockage, and intracanal instruments fracture. These in turn may affect the short and long-term treatments’ outcomes. Clinicians need to be aware of such unpleasant incidents and their contributing factors. In addition, they need to understand and implement strategies and methods that prevent these procedural mishaps. This clinical-based lecture will highlight and explain clinical tips and procedures that help clinicians to safely clean and shape root canals systems, including those of difficult anatomical configurations.

The demand for predictable treatment modalities in regenerative medicine continues to escalate as researchers seek to gain a better understanding of the cellular and molecular mechanisms involved in regeneration and as clinicians seek more predictable outcomes and user-friendly techniques. Further development of this powerful protein therapeutics has been achieved by combining them with tissue-specific biomaterials to provide a substrate for new tissue regeneration as well as an ability to attenuate release of the recombinant growth factor. To appreciate the significance of this new class of regenerative therapeutics, it is helpful to understand the basis for their emergence.

Success of pulp revascularization in pregnant women: histological and molecular study

Asmaa HOUMMADI (Morocco) - Said DHAIMY(Morocco)

Revascularization is a new therapeutic approach for immature teeth with necrotic pulp. An alternative approach to organic bases which, unlike artificial apical barrier techniques, allows the continuation of root development and the recovery of pulp vitality. It rests on tissue regeneration, which is based on multidisciplinary principles that maintain the functionality of the tooth. It involves growth factors, biomaterials and stem cells. All three factors can be manipulated to ensure the regeneration of functional pulp tissue, as in the case of changes during pregnancy in women, where there is an increase in serum concentrations of growth factors, hormones, and a significant increase in stem cell stock, these modifications that characterize the period of pregnancy in women are the consequence of the adaptation of the body of the surrogate mother to ensure a good embryogenesis, pregnancy is then the only period that promotes the regeneration mechanisms in an adult person. Nevertheless, it is necessary to take advantage of this rather special period to carry out some healing and regeneration therapies. Our objective is to study the relationship between the success of pulpal revascularization therapies and the state of pregnancy in women.

Pulpal response after fragment reattachment of fractured incisors, clinical cases.

Sara DHOUM (Morocco)

The Aim of this work is to show, through two clinical cases, the pulpal response following a permanent traumatized permanent tooth: enamel-dentin fracture without pulpal involvement.
The pulp reactions of traumatized teeth have been the subject of many investigations, and have been for years nominal. The healing of the pulp is multifactorial and depends on what is done (intrinsic to the neurovascular bundle, pulpal immune potential) and severity and multiplicity of trauma, therapeutic management, bacterial contamination
Cases presentation
20 years old female patient consulting after a dental trauma related to #11
The clinical and radiographic explorations didn’t show any pulpal implication. The fragment of the injured tooth were brought and the decision of the reattachement of the fragment were made; Follow up : 1 week, 3 months and 18 months has showed no pulpal or peri-apical complications.
22 years old female patient consulting after a dental trauma related to #21
The clinical and radiographic explorations didn’t show any pulpal implication.
The fragment of the injured tooth were brought and the decision of the reattachement of the fragment were made. 2 weeks follow up showed severe pain related to the injured tooth and we proceeded to the endodontic treatment of the tooth, 24 months follow up has showed no peri-apical complication.
Discussion
If the neurovascular bundle is intact or partially damaged and in case of bacterial infection, pulpal survival is possible. Within the pulp, regressive changes are nonetheless observable, notably with hyalinization and the deposition of diffuse and amorphous calcifications.
Canal obliteration, also known as PCO (pulp canal obliteration) or calcifying metaplasia, is a frequent consumption of trauma, auto-transplantation or orthodontic treatment. It can be partial or total. In the retrospective study of Oginni et al.
on the exposed teeth of the canal obliterations, 56.9% of the traumatized teeth, on a partial obliteration and 43.1% a total obliteration. The etiology is currently unknown. Several hypotheses have been put forward. It could be related to an alteration of the blood circulation caused by the uncontrolled formation of calcified tissue along the canal walls.
The pulp bleeding and blood clots were pathological mineralization zones. This must be considered as a response to severe damage to the vasculo-nervous bundle. According to Andreasen, this would be an uncontrollable response of the sympathetic nervous system in response to trauma, resulting in particular from the loss of inhibition of the parasympathetic nervous system. Finally, according to Torneck, pulp calcification would come from a simple stimulation of pre-existing odontoblasts increasing their secretion rate.
Pulp necrosis can occur immediately when the trauma is responsible for the section of the vascular bundle without the possibility of pulpal revascularization.

Immediate dentin sealing in direct posterior restoration after endodontic treatment.

Mohamed Amine TALHAOUI, Said DHAIMY (Morocco)

Cleaning a tooth from decay, opening the pulp with the most conservative cavity access, performing the best mechanical and chemical preparation and getting to tee the most impervious obturation on x-ray doesn't mean that our job regarding to our patient is done. Because the best endodontic treatment with a bad coronal restoration may lead to failure due to: cracks, coronal leakage, lost of coronal restoration, vertical fracture... That's why nowadays, indirect ceramic restorations are indicated for most of those cases. Immediate dentin sealing, described by Pascal Magne, allows us to do those indirect restorations, such inlays, onlays, endocrowns of even crowns by applying an adhesive resin to the freshly cut dentin when a significant area of dentin has been exposed during tooth preparation. The advantage of immediately bond freshly cut and clean dentin is to significantly increase retention, reduce marginal leakage, and improve bond strengths. During tooth preparation, the clinician can focus on the “wet bonding” to dentin, while dry enamel bonding can be performed at the stage of restoration bonding. That way we obtain a sealed dentin which is protected from bacterial leakage/infiltration during the provisional restoration, thus enhancing patient comfort. The aim of this presentation is to describe how to do Immediate Dentin Sealing step by step from rubberdam to bonding, to increase success rate of our endodontic treatment and survival rate of those treated tooths.

Vital pulp therapy in cariously exposed permanent teeth

Radia SKALLI (Morocco)

Lecture: Endodontic emergencies and triage

The aim of this oral presentation is to discuss the current and new options of preserving vital pulp therapy within going to root treatment, but also to expose, through clinical cases, the interest and importance of vital pulp therapy. The discussion will treat the different success and failure rates reported in the literature.
t is believed that a lot of root canal treatments and tooth extractions could be avoided if the proper pulp diagnosis of the teeth is carried out. Indeed, the exposed permanent teeth remain one of the most controversial areas in dentistry. Because a vital, functioning pulp is capable of initiating several defence mechanisms to protect the body from bacterial invasion, it is beneficial to preserve the vitality of an exposed pulp rather than replace it with a root canal filling material following pulp exposure.
Vital pulp therapy (VPT) is a biological approach to minimally invasive endodontics. The aims of vital pulp therapy include the maintenance of vitality and preservation of the remaining pulp for adequate structural and functional healthing of the pulp-dentin complex. With the development of biomaterials such as bioceramics and advances in pulp biology such as the identification of dental pulp stem cells, novel ideas for the preservation of dental pulp, the regenerative therapy of dental pulp, and new biomaterials for direct pulp capping have now been proposed.
There are several different treatment options of vital pulp therapy in extensively decayed. Pulp capping or pulpotomy procedures rely upon an accurate assessment of the pulp status and careful management of the remaining.

Preventive endodontics

Bio-conservative therapies (direct pulp capping, partial pulpotomy, cervical pulpotomy) aim to preserve the vitality of the pulp and its defensive functions against bacterial aggression. However, their indications for exposure to decayed dentine is controversial as the success/survival rates of these therapies remain relatively low.
The objective of this oral communication is to recall the knowledge necessary to optimize pulp vitality conservation therapies and to detail the factors influencing prognosis through clinical situations of pulp vitality conservative therapies. Clinical cases of pulp exposure management using bioactive materials will be detailed step by step, from dental caries removal procedure to final filling with follow-up. A better knowledge of pulp biology and the recent development of bioactive materials have made it possible to reconsider the systematization of endodontic treatment in the event of pulp exposure. The prognosis for pulp capping depends on the material used, the age of the patient and the topographical location of exposure and, above all, the inflammatory status of the pulp.
Bioactive materials have evolved considerably over the past ten years, including consideration of bioactivity properties, which has contributed to a renewed interest in pulp vitality preservation techniques. However, the clinical evaluation of the inflammatory status of the pulp remains the main obstacle to the systematization of this procedure.

Root canal system is so complex, presence of anastomosis, isthmuses and lateral canal exhibit a challenge for the clinician to 3 dimensionally seal the root canal system.
One of the main goals of Endodontic treatment is to prevent reinfection hence come the role of obturation and 3D sealing to root canal system to provide sufficient apical and coronal seal against bacterial re invasion.
The use of warm gutta percha and vertical compaction is considered the gold standard technique for obturation.
In this workshop we’ll discuss the rationale behind 3D obturation techniques, what are the needed tools and how to master the 3D obturation techniques.

Le médecin dentiste est amené à rencontrer dans sa pratique quotidienne des patients présentant un tableau clinique délicat de pathologie du sinus maxillaire. Il doit donc pouvoir relever les signes cliniques et interpréter les examens radiologiques 2D ou éventuellement 3D qui lui permettront de poser un diagnostic adéquat afin de traiter, orienter le mieux possible son patient pour une thérapeutique optimale.
Les étiologies les plus fréquentes sont infectieuses et inflammatoires. La pathologie carieuse en est le meilleur exemple. La pathologie iatrogène, notamment la chirurgie pré-implantaire ou implantaire, ainsi que les tumeurs bénignes ou malignes sont également responsables de ces pathologies.
Le diagnostic et la prise en charge nécessitent un raisonnement clinique structuré basé sur une approche clinique et radiologique précise.
Les objectifs de cet atelier sont :

  • Maitriser les signes cliniques des pathologies sinusiennes les plus fréquentes.
  • Apprendre à explorer le sinus maxillaire au niveau des examens radiologiques de routine (panoramique et Cone Beam).

Le laser en endodontie.

Hafsa El Merini (Morocco)

The endodontic treatment aims to remove organic pulp tissue and bacterial irritants, carry out a conical and regular preparation while respecting the initial canal path and preserving the apical structures.
The root-canal system is complex as residual infected pulp could be found in both the lateral canals and in the apical structures of vital and necrotic teeth associated with peri-radicular inflammation after the completion of chemo-mechanical preparation.
The shaping, disinfecting and cleaning of the root canal could be achieved with increasingly innovative instrumentation and active irrigation solutions. The efficiency of these solutions can be increased by physical means such as lasers.
Lasers have been introduced in dentistry for about twenty years. There are different wavelengths which make the laser more or less penetrating (Diode 810 or 980 nm, Nd-YAG 1064 nm, Nd-YAP 1 340 nm) or absorbed mainly by water and hydroxyapatite (Erbium Chromium -YSGG 2780 nm, Erbium-YAG 2 940 nm, CO2 10 600 nm).
Used in endodontics, some wavelengths activates the irrigating solutions within the canal. The technique is called laser-activated irrigation (LAI). It has been shown that the LAI is more effective in removing debris, bacteria and the smear layer in root canals compared with traditional techniques.
The laser will act by photomechanical, photochemical, photo-acoustic, and photo thermal effects.
The aim of this work is to shed light on lasers in endodontics, their use, their effects and their contributions in debridement, cleaning and decontamination of the intra-radicular space.

Pr Mehdi JOUHADI (Morocco)

Fiber posts have been developed to improve the mechanical tooth protection and the optical effects of aesthetic restorations. They are widely used for restoring endodontically-treated teeth and it’s is gaining widespread acceptance in general practice.
However, many questions about root preparation, indications for posts’ use, different cementation protocols, adhesive systems and critical clinical cases still need to be discussed and clarified.
Theses technical aspects would be revised and summarized in this workshop to instruct the dental practitioner about the current concepts and evidence for the fiber posts use.

Broken file bypass (when, why and how).

Dr Waleed Kurdi (Egypt)

Radicular separation of endodontic instruments is the worst nightmare facing every dentist in the modern dentistry.
Instrument separation inside the canal worsens the root canal procedures and make cleaning and shaping the canal more difficult.
Hindering the procedures will affect the outcome and the prognosis of the case.
Separation mode is a complicated phenomenon affected by many factors which I will clarify in my lecture and how to prevent that.
Managing a separated instrument will range from orthograde to surgical option.
Orthograde conservative conventional options including removal or bypassing the fragment will be the specific part of our lecture.
A decision should be taken either to bypass or to retrieve according to many affecting factors which I will clarify.
The main goal is not only removing the separated fragment but also the tooth integrity should be maintained so bypass is a good option in many situations.
I will clarify when, why and how to bypass a broken file fragment through different protocols and trials.
Clinicians should be familiar with all options in facing broken file cases even before referral if needed.

Bioceramics in Endodontics: What is true and what is new?

Shehabeldin Ismael (Egypt)

Recently, a number of major advances have been made in the field of bioactive ceramics used for endodontic treatment. The documented biocompatible nature and excellent physico-chemical properties extended the range of endodontic applications of these materials. This lecture, through presenting clinical cases and videos will demonstrate the use of Bioceramics in vital pulp therapy, regenerative endodontics, root repair procedures, trauma cases, internal and external resorption cases, apical surgery and as root canal cements. For each application, a quick review of the literature will be emphasized to highlight technique variables and expected clinical outcomes.

Strategies for successful pulpotomy in definitive mature teeth.

João Miguel Santos (Portugal)

The purpose of vital pulp therapy is to maintain the health of all or part of the pulp in normal or inflamed pulps. This group of treatments includes pulp capping, partial and total pulpotomy. Pulpotomy has been recommended and a widely accepted treatment for carious or mechanic pulp exposure of permanent immature teeth, with pre-operative normal or reversible pulp inflammation. In recent years, improved biological knowledge about pulp regeneration and the development of new bioactive materials increased the interest in pulpotomy. Particularly, in managing immature and mature permanent posterior teeth with reversible and irreversible pulpitis, as an alternative to apexogenesis and conventional endodontic treatment. The good results obtained with those clinical protocols, encouraged some clinicians and endodontic associations to suggest minimally invasive therapies for treatment of mature permanent teeth with preoperative inflammation, in order to maintain the pulp’s developmental and defensive responses. Conventional root canal treatment (RCT), especially in posterior teeth, is a technically demanding and expensive treatment. Therefore, more conservative treatment approaches with improved outcomes are welcome to ameliorate the oral health status of the population and delay more invasive options. However, there are gaps in the current knowledge on the biological mechanisms underlying these protocols that needs to be clarified.
The main objectives of this presentation are: 1) Explaining the histopathologic basis for clinical application of pulpotomy; 2) Discuss the benefits of pulpotomy over conventional RCT; 3) Analise the impact of preoperative pulp inflammation on the outcome of pulpotomy and biological characteristics of new calcium-silicate materials.

Post Endo Restoration.

Serge Bouillaguet (Switzerland)

Over the past thirty years, restorative dentistry has seen a revolution in materials, restorative techniques, and patient priorities. This revolution has been made possible with the development of new resin-based materials which can be bonded to the tooth structure. However, there is evidence that the bonding performances of resin-based materials to root dentin are lower compared to coronal dentin. Factors affecting bonding to root dentin have been clearly identified and new procedures for restoring the function of non-vital teeth have been recently established. Although the use of a crown built on post and core remains a traditional approach, the use of direct composite resins for restoring small defects or indirect restorations such as overlays or endocrowns made of composite resins or ceramics for the restoration of larger defects are increasing. This presentation will focus on the selection of appropriate restorative materials and techniques to be used according to the amount of remaining tooth structure in order to increase the long-term prognosis of endodontically treated teeth.

Non surgical retreatment with modern technology: Microscope and CBCT.

Arnaldo Castellucci (Italy)

In recent years in Endodontics there has been a true explosion of new technologies, new instruments and new materials, which made predictable many procedures that before were considered impossible or just made by chance. The most important revolutions have been the introduction of the Surgical Operating Microscope and the Cone Beam Computed Tomography. With the use of the operating microscope everithing is changed both in non-surgical and in surgical endodontics. In non-surgical endodontics, every challenge existing in the straight portion of the root canal system, even if located in the most apical part, can be easily seen and then solved under the microscope, with magnification and coaxial illumination.
The otjher revolution is represented by the introduction of the CBCT. It is well known that the traditional bi-dimensional radiographs have several limitations.
The information obtained with the use of the CBCT are digitally reconstructed and interpreted to create an interface whereby the clinician can three-dimensionally interpret “slices” of the patient’s tissues in a multitude of planes: axial, sagittal and coronal CBCT is a simply, valuable, reproducible, reliable, relatively economic and task- specific imaging modality exposing the patient to a relatively low radiation dose and providing the maximum amount of information to the clinician when performed with the right equipment and acquisition protocols.
CBCT makes clinical decision making easier and more precise, patient treatment decisions more accurate, and visualization of the x-ray data more meaningful. Dentistry is moving away from “radiographic interpretation” and into “disease visualization”. Thanks to all these revolutionary progresses, the long term success rate of root canal treatments is higher and endodontic therapy today is more predictable and even more fun!

Are we doing a good job?

Ibrahim Abu Tahun (Jordan)

Dentists are hand piece oriented. Too often we think in terms of mechanical instead of other creative approaches that elicit biological responses and make biologically based decisions.
‘What your patients would choose if they understood the difference between destroying tooth tissue and conserving it and the associated biological costs.”
With original conventional RCT, we always aimed at regenerating a functional pulp - dentin complex which reflects the tremendous capacity of our body to deal with infection and heal.
Do good root fillings 'really' impose the outcome of endodontic treatment?
If we consider that successful treatment does not necessarily sterilize the root canal, we come to the task with significant, bias from our training. Our bias may trick us into thinking, we know something when we don’t.
We just now starting to understand how complex this situation is. To me, the unequivocal answer is, good enough is not good enough.
RCT leaves always chronically infected teeth although they relieve patients’ symptoms.
Sadly, our teaching is often narrowly focused without addressing alternatives.
Despite many doubts and too many pitfalls, this presentation will discuss how regenerative endodontics represent huge heritage for the next generations of dental researchers and clinicians.

The current clinical aspects of endodontic surgery

Silvio Taschieri (Italy)

Periapical disease associated with root-filled teeth must be evaluated carefully to determine whether to use non-surgical re-treatment, surgical re-treatment or tooth extraction. Extraction is sometimes performed, which is disappointing, because orthograde retreatment or apical surgery can be used. Large cross-sectional studies from different countries have reported that the prevalence of apical periodontitis or other post-treatment diseases can exceed 30% of all root-filled teeth in the population. These data suggest suggest a great need for treatment of this condition. Microsurgical instruments, ultrasonic retrotips and root-end filings improve the outcome of periradicular surgery considerably compared with traditional techniques. Such devices have brought advantages for the management of the root-end. Several authors have reported a high success rate after periradicular surgery, suggesting that the use of a surgical microscope might have been a decisive factor contributing to the excellent outcomes. In this lecture will be showed step by step the modern endodontic surgery technique in case of different lesion size and characteristic, especially the one which involved management of maxillary sinus in micro-endodontic surgery.

The role of irrigation in root canal treatment

Pierre Machtou (France)

Irrigation combined with instrumentation is an essential part of the root canal treatment. The aim of the shaping procedure is to create space to irrigant delivery to clean and disinfect the root canal system and then to filling materials placement. The ultimate goal is to eliminate debris and bacteria from the root canal system to expect predictable success. However, research has shown that complete debridement is impossible to achieve with the syringe delivery of irrigants (static irrigation). Indeed, the apical region and the intricacies of complex root canal systems are the most difficult areas to clean with this traditional method. Currently, activation of irrigants (dynamic irrigation) at the end of the cleaning and shaping procedure is advocated to help distribute irrigants into these restricted areas. The objective of this presentation is to review the different irrigating solutions and protocols including the current methods of irrigant activation, assess their pros and cons and consider potential developments for the future.
At the end of the presentation, the participants must :
- be able to assess the benefits and limitations of the main irrigants used in clinical practice
- be able to know the limitations of syringe delivery and how to improve it
- be able to know and assess the pros and cons of the current methods of irrigant activation

New wave in endo diagnostics: perform, trust or forget?

Zivile Grabliauskiene (Lithuania)

There are many cases in dentistry when it is essential to know the pulp status to initiate the most conservative treatment and avoid complications and expances if a disease is not diagnosed and untreated. Dental trauma, tooth caries, dentin hypersensitivity require accurate evaluation of pulp vitality. There is no ideal method of the pulp vitality. In our days thermal and electrical tests to determine pulp vitality can give a false results, because they can determine only pulp innervation but not vascularity. The vascular supply is more important to the determination of the pulp vitality than the sensory supply. Experimental diagnostic methods to assess the blood supply (Isotope clearance, local hydrogen-gas desaturation, labelled microspheres) are experimental. Pulse oxymetry is a non-invasive completely objective test in evaluating vascularisation by determining oxygen saturation level in the circulating arterial blood. It could be useful in cases of impact injury where the blood supply remains intact but the nerve supply is damaged. Will be discussed about advantages and critical requirements of using pulse oximeter and laser doppler flowmetry in dentistry, as only usefull methods for pulp vitality.
Objectives:
1. The cold and electro tests are not objective to diagnose the status of the pulp.
2. In daily clinical practise we need more effective and objective method of evaluating dental pulp vitality.
3. Studys confirms the potential use of pulse oximeter as a dental pulp vitality tester.

Endodontics: "Past, Present, and Future"

Adil Alani (UAE)

Clinical evaluation and periapical radiographs have been methods traditionally validated by randomized clinical trials and systemic reviews in the success of endodontic treatment. Also, the presence or absence of preoperative periapical lesion, the complete isolation of the operative field, in addition to the density and extension of the root canal treatment, and the quality of coronal seal have been identified as factors that influence the prognosis of the treatment. This presentation will focus on treatment planning, and the biologic approach to endodontics that has evolved as part of a multi-disciplinary care of patients. Philosophy of treatment is based on three concepts: Confidence, Communication and Competency. Confidence defines how practitioners feel about themselves and the way patient’s feel about their dentists. Endodontics itself is predictable 97% of the time; developing the confidence to provide health and success for our patients during these times of medical and technological change will be addressed in the presentation. Communication on the other hand should always be established between the patient and doctor. This relationship is based on respect, friendship and total loyalty. Competency is driven by biology and a complete understanding of the masticatory system in health and disease. In addition, a treatment’s success is dependent on the patient’s desire to follow through with all recommendations, maintenance and subsequent treatment. We will conclude with where we are today and what is the future in the specialty of endodontics. At conclusion, participants should be able to: 1. Establish the correct strategy to achieve a good prognosis

Endodontic Rotary Systems: The Illusive Quest For Perfection

Essam Zaatar (Kuwait)

Lecture: Endodontic emergencies and triage

Modern technology constantly continues to evolve in providing clinicians with new endodontic rotary systems. The more we understand the anatomy of the pulp cavity, the more caution we become in choosing what we think is a suitable system for a specific tooth. It is our duties as clinicians to understand how these systems differ in terms of their files’ design, metallurgy and proposed mode of rotation.
This presentation should enable the audience to:

  • Appreciate the complexity of the root canal system.
  • Understand how the popular rotary systems differ.
  • Safely use multiple systems in different case scenarios.

Anatomically Invasive Endodontics.

Gianluca Plotino (Italy)

Clinical studies demonstrate that long term prognosis of the root filled teeth is influenced by the quality of the restoration as well as by the quality of the root canal treatment itself. The most recent trends in restoration of endodontically treated teeth are following the concept of minimally invasive dentistry, proposing more conservative, less expensive and bio-economic restorations, based mostly on adhesive dentistry and the introduction of new materials and technologies. Following these trends, the access procedures in endodontics and the root canal preparation are changing in a conservative way, sometimes drastically if compared with the traditional concepts of cavity outline opening and coronal straight-line access to reach the apical region. Endodontic literature appears to be poor on demonstrating how these minimal invasive access procedures can influence the quality and prognosis of root canal treatment. The present lecture will analyze the technical procedures of minimal invasive access in different clinical situations and the possible mechanical improvements derived from it. Moreover, the limits of these procedures will be critically analysed to define how much minimal invasive clinicians should be in order to ensure « gold standard » endodontic treatments.
AIMS AND OBJECTIVES
At conclusion, participants should be able to:
• Describe the basic concepts of access cavity preparation.
• Perform new strategies to optimize access cavity preparation.
• Evaluate critically the advantages and disadvantages of present technologies, instruments and techniques.

Reducing risk or increasing favorable outcome: what do we really need?

Sanaa CHALA (Morocco)

Introduction: Outcome of endodontic treatment is a clinically important question that should be discussed before treatment. Depending on the outcome measure, clinical decision making may varied because different outcomes are expected for diverse people and conditions. Many studies uses the rate of success and failure of endodontic treatment to assess the outcome. However, the rate of success and failure considered alone may provide limited information on how meaningful measures of treatment effect can be derived. Aim: The aim of this presentation is to discuss the value of the clinical question to be addressed: rate of “success” or risk reduction depending on clinical condition. Methods: Published data on endodontic outcome were identified through medline and endodontic journals. Prognosis studies and clinical trials were identified to record the outcome measure usually used. Case studies will be used and discussed to assess the applicability of these measures. Objectives: Determine the specific question to be addressed for clinical decision-making/ to estimate clinically meaningful measures of treatment effect and open up discussion on considering the clinically meaningful measures of treatment effect.

Do we really need to activate our irritant?

Mostafa ELKHOLY (Egypt)

Lecture: Endodontic emergencies and triage

The major causative role of microorganisms in the pathogenesis of pulp and periapical diseases has clearly been demonstrated, hence the goal of endodontic treatment is to remove all the vital and necrotic tissues, microorganisms and microbial by-products from root canal system. However, the root canal complexity and the sophistication of the microbial biofilm suggested a shift from the static needle- delivered irrigation method to the dynamic activated irrigation techniques. In the last decades, several methods of irrigant activation was developed, tested and adopted by endodontists all over the world. But in the era of evidence-based dentistry it is important to understand that laboratory studies are required for the development of endodontic instruments, materials and techniques, and when they are designed with the same scientific rigour used for in vivo studies, they provide valid information that can inform the design of clinical research. However, considering the limitations of extrapolating the results of laboratory studies to clinical reality, the biological basis of clinical outcomes, bacterial reduction, etc... has to be evaluated by a clinical trial. Therefore, clinicians have to carefully evaluate available scientific data before adopting new techniques. So proper evidence synthesis of the efficacy of different activation methods and their impact on the clinical outcome of the root canal treatment will be reviewed to determine the necessity and the benefits of irrigant activation. Objectives: Review on root canal disinfection challenges. Different activation and agitation protocols. Evidence synthesis of the efficacy of different activation and agitation protocols.

Aim: This study aimed to evaluate the antibiofilm efficacy of chitosan nanoparticle and photodynamic therapy conjugated with chitosan nanoparticle on dual-species biofilm using Confocal Laser Scanning Microscopy (CLSM). Methodology: A total of 90 dentin section blocks were prepared to be (4×4×1 mm) (Width × Length × height) respectively. Each dentin section was placed in a 1.5 mL polypropylene tube filled with brain heart infusion (BHI) broth then underwent sterilization. Cultivation of standard strains E. faecalis (ATCC 29212) and Staph. Epidermidis (ATCC 12228) bacteria were prepared then inoculated on dentin section blocks and incubated for 3 weeks at 37°C for the formation of mature dual-species biofilm. The specimens were grouped into 4 groups according to the final rinse used. G1: final rinse using chitosan nanoparticles, G2: final rinse using Rose Bengal dye (Photodynamic Therapy), G3: final rinse using chitosan nanoparticles conjugated with Rose Bengal dye (Photosensitizer-functionalized Nanoparticle), and G4: control group (Non-treated bacterial group).The efficacy of the tested final rinse solutions on dual-species biofilm was evaluated using Confocal Laser Scanning Microscopy (CLSM) and data were statistically analyzed. Results: the highest mean percentage of dead bacteria was found in Group (3) (88.38% ± 5.45), while the least mean percentage of dead bacteria was found in Control Group (4) (7.25% ± 1.12) with a statistically significant difference between groups where (p<0.001).

Endodontic strippings and perforations: management standards update and outcomes overview

Imane EL OUARTI (Morocco)

Endodontic perforation is a pathologic or iatrogenic communication between the root canal system to the supporting tissues of teeth or to oral cavity which can occur accidentally during or after endodontic treatment. Stripping perforation is known as an iatrogenic excessive loss of radicular dentin in the coronal two thirds of the tooth. Root canal strippings and perforations predispose root to fracture and lead to inflammatory processes in the tooth periodontal attachments which reduce the chance of successful treatment outcome and can jeopardize the survival of the tooth. Successful perforation repair depends on the ability to seal the perforation and re-establishing a healthy periodontal ligament. Several key factors have been associated with the prognosis of the tooth; these include the location of the perforation, the size of the perforation, the time to repair and most recently the repair material. Dealing with long-standing perforations, the presence of profuse bleeding, ensuring decontamination of the perforation site are the most challenging. Apex locators, ultrasonic instruments, bioactive materials provide nowadays better opportunities for diagnosis and perforations management. This presentation will be illustrated with various clinical cases to describe the general principles and new advances in diagnosis, repair of endodontic perforations and management of related complications, and aims at highlighting the following next key points:
-management of inflammatory conditions related to endodontic strippings and perforations.
-help practitioners in the choice of the repair material between the most widely discussed (MTA VS Biodentine)
- illustrate with clinical cases the short and long-term outcomes after repair.

The Effect of Acemannan on Increasing Expression of BMP-2 and RUNX-2 Osteoprogenitor Cells in Osteoblast

Yuli NUGRAENI (Indonesia)

Objective: Aloe vera is one of popular plants. One of the active ingredients is the acemannan polysaccharide. The acemannan is given, exstraction from pure aloe vera and is a polysaccharide poliosaosa which is betaacectylad which is able to stimulate fibroblasts and osteoblasts to help proliferation, differentiation and mineralization of osteoprogenitor cells. In osteoblasts there is activation of TGF beta, osteocalcin, osteopontin and stimulated RUNX-2 osteonectin and BMP-2. RUNX-2 and BMP-2 is a key transcription factor associated with osteoblast differentiation.
Purpose: This study aims to determine the increase in RUNX-2 and BMP-2 expression in osteoblast cell osteoprogenitor and by administrated 100g and 200g acemannan.
Methods: This study was conducted in a true laboratory exsperimental design with a Post-Test only Control Group Design. This analysis consisted of 3 groups, namely osteoblasts cell with standart medium, while the group was a group with osteoblasts cells with 100g acemannan and 200g acemannan. Then compared between negative control groups, treatment 1 and treatment 2. The result are expressed as mean standard deviations and graphs. The display of positive values is shown by photos of brown color osteoblasts cell micrografts in the cell cytoplasm. The result is determine that Acemannan could increasing RUNX-2, BMP-2 and osteoblast significantly (p>0,05). Conclusion: The Acemannan has the potential to increase expression of BMP-2 and RUNX-2 Osteoprogenitor Cells in Osteoblast.
Keywords : Acemannan, osteoblasts, RUNX-2 and BMP-2

Les atteintes dentino-pulpaires chez l’enfant : démarche diagnostique et thérapeutique.

Pr Amal CHLIYEH (Morocco)

Le diagnostic de l’état pulpaire n’est pas aisé à établir chez l’enfant. En effet, la confrontation des données cliniques et radiographiques est souvent insuffisante en raison des particularités anatomiques, histologiques et physiologiques des dents temporaires et permanentes immatures.
Or, il est primordial de déterminer la santé de la pulpe ou son stade d’inflammation pour choisir le traitement le plus approprié parmi les différentes thérapeutiques dentino-pulpaires décrites pour ces dents.
Dans cet atelier, les participants analyseront plusieurs cas d’atteinte dentino-pulpaire d’origine carieuse aussi bien sur les dents temporaires que permanentes immatures.
Pour chaque situation clinique, la démarche diagnostique, la décision thérapeutique ainsi que les matériaux recommandés et le suivi seront discutés.

2 Shapes : deux instruments pour une mise en forme canalaire facile.

Pr franc DIEMER (France)

Résumé : Si le nettoyage et la mise en forme sont nécessaires à la réussite du traitement endodontique, les innovations actuelles portent principalement sur la modification de paramètres géométriques des instruments, tels que la section transversale, l’angles d’hélice, les angles d’attaques et de nombreuses autres spécifications qui caractérisent un instrument donné. Ces évolutions ont permis de réduire considérablement les ruptures instrumentales qui hantent toujours les utilisateurs de NiTi et ont poussé les concepteurs dans de nouvelles directions. Dans le même temps, les praticiens aspirent à une efficacité de coupe optimale avec des sensations douces. Le traitement thermomécanique des fils NiTi avant, pendant ou après l’usinage des instruments endodontiques a amélioré leur flexibilité. Ces procédures de traitement innovantes ont ouvert la voie à un tout nouveau domaine d'alliage NiTi avec une composition atomique microstructurale spécifique.
En combinant les connaissances sur la conception des instruments et les nouvelles procédures de traitement thermique, Micro-Méga a conçu le One Flare et le 2Shape. Ce nouveau système ne comprend que deux limes de rotation continue pouvant mettre en forme la plupart des configurations canalaire.
Avant l'atelier, nous décrirons le système et expliquerons comment utiliser cette séquence endodontique simple, sûre, efficace et courte en mouvement rotatif continu.
À la fin de cet atelier, les participants seront en mesure de :

  • Comprendre la capacité de nettoyage et de mise en forme du 2Shape ;
  • Faire un traitement endodontique plus facile et plus sûr ;
  • Apprécier la sensation douce des instruments… diminuant ainsi le stress de l’opérateur.

2 Shapes : deux instruments pour une mise en forme canalaire facile.

Taha Özyürek, Mustafa Gündoğar (Turkey)

Since 2008, reciprocating motion regained popularity with the combination of nickel-titanium and endodontic torque control motors with software allowing unequal clockwise and counterclockwise motions. The new unequal reciprocating motion aimed mainly to improve mechanical properties of the endodontic files such as cyclic fatigue, and to obtain more centered preparations with less procedural errors compared to continuous rotation. In addition, reciprocal motion gained acceptance among dental faculties, general practitioners as well as Endodontist worldwide due to its simplicity of use, the lack of procedural errors during cleaning and shaping in a short time period. Nowadays these advantages of the reciprocal NiTi files have been improved due to new heat treatment methodology that applied to NiTi files.
In this workshop:

  • Participants will be able to know the correct use of current nickel-titanium file systems will have the opportunity to make root canal shaping with these systems.
  • Participants will have detailed information about new reciprocating file T-endo Must.

Rotation continue ou réciprocité : 2 philosophies pour une mise en forme canalaire réussie.

Pr Nisrine ARROUF (Morocco)

Le traitement endodontique est un acte protocolé, qui ne pardonne pas l'approximation, et dont le succès est largement tributaire d'une mise en forme canalaire minitieuse.
Si les principes sont restés immuables depuis les années 70, l'avènement du NiTi couplé à la rotation continue, vingt ans plus tard, a changé la pratique de l'endodontie au quotidien.
Puis une nouvelle dynamique instrumentale, basée sur le concept des forces équilibrés, a été introduite en 2008. Il s'agit du mouvement de réciprocité ou Mouvement Alternatif Transversal Asymétrique (MATA).
En parallèle, l'évolution des séquences instrumentales vers la simplification ne cesse de s'accélèrer, ce qui rend le choix pour l'omnipraticien difficile face à une offre pléthorique et des arguments commerciaux difficilement vérifiables.
Durant cette session, nous allons analyser ensemble, à la lumière de la littérature, l'apport de chacune des dynamiques instrumentales ainsi que leurs limites.
Dans un deuxième temps, une séance de travaux pratiques sur simulateurs, vous permettra de vous familiariser avec ces deux techniques de mise en forme canalaire, et peut-être de choisir la dynamique instrumentale la plus adaptée à votre pratique quotidienne.

Les patients à risque hémorragique et infectieux en odonto-stomatologie.

Pr Sofia HAITAMI - Pr Lamia Kissi (Morocco)

Les patients à risque représentent une partie minoritaire mais non négligeable de la patientèle du cabinet dentaire. En effet, le vieillissement de la population ainsi que l’augmentation de la prévalence des maladies cardio-vasculaires font que bon nombre de patients que nous recevons présentent une pathologie ou une médication pouvant interférer avec notre prise en charge bucco-dentaire.
En effet, le médecin dentiste peut, soit directement par son geste ou ses prescriptions, soit indirectement par l’interruption d’un traitement exposer son patient à un risque, hémorragique ou infectieux. Il doit, de ce fait, être à jour en ce qui concerne les différentes recommandations de prise en charge des patients à risque afin de ne pas exposer ses patients à des complications pouvant être graves.
L’objectif de l’atelier est d’appliquer les différentes recommandations internationales sur des cas cliniques et de discuter les différentes éventualités de prise en charge des patients à risques hémorragique et infectieux.
Ainsi, seront discutés les cas des cardiopathies, de diabète, d’hypertension, d’hépatite…
