Session Chair: Angus Walls

Apical periodontitis (AP) is a multifactorial disease related to the inflammatory response to the endodontic infection, and is normally resolved with correct instrumentation, disinfection and obturation of the root canal system. Nevertheless, according to recent reports, not only the prevalence of AP is becoming more frequent worldwide, but in particular the incidence of persistent AP (PAP) in treated teeth is increasing. The most important clinical factors related to persistent AP, have to do with residual infection in uninstrumented volumes of the root canals. In recent years, it has become evident that also systemic conditions affecting the patients, on one hand, and, most important, individual genetic predisposition to substain a stronger immune-inflammatory response, on the other hand, may influence the development and presentation of AP and its healing response to endodontic treatment. Taking into account the patient may help predicting the outcome of endodontic treatment, future protocols may address how to enhance healing by complementing treatment of AP with medications.

Session Chair: Angus Walls

Deciding when to root treat or extract a tooth can be challenging and requires us to consider many inter-related factors; the tooth’s endodontic and periodontal status, as well as the structural integrity (the restorability), must be assessed. These factors must also be contextualised in relation to the patient’s medical and dental conditions, as well as the patient’s expectations and the clinician’s clinical skills (the context).  

This presentation will describe an elegant method of assessing restorability of teeth, crucially, it will be backed up with good evidence.

Session Chair: Paul Abbott

The pulp plays a key role in the treatment of traumatic dental injuries (TDIs) and is strongly associated with the outcome, particularly in severe cases. A correct pulp diagnosis is essential as it forms the basis for developing the appropriate management strategy. However, many TDIs are complex, and their treatment requires a profound knowledge of the physiological and pathological responses of the affected tissues. 

The endodontic management of traumatized teeth should aim to avoid root canal treatment if preservation of the pulp is a realistic scenario but at the same time should be directed towards early endodontic intervention in teeth of high risk of developing infection-related root resorption. 

Future research should pay greater attention to (1) diagnostic methods to assess the perfusion of the pulp and enhance detection of tooth cracks and initial signs of root resorption; (2) improved materials for vital pulp treatment; (3) studies focusing on type and duration of splinting after root fractures; (4) antiresorptive intracanal medication in case of posttraumatic pulp necrosis and infection-related resorption and (5) long-term data on the apical barrier technique compared to revitalization. 

Graduated as a dentist in 1978 at the Catholic University of Leuven, Belgium. Obtained his PhD at KULeuven in 1983 based on a thesis investigating dental composites: "Basic properties of dental composites and their impact on clinical performance". Today, he is Professor Emeritus at the Department of Oral Health Sciences and is still involved in teaching for postgraduate students endodontology. He was Program-Director of the dental Bachelor/Master and Master-after-Master programs at KULeuven for 27 years. He teached cariology and endodontics. His research focussed on endodontics. More specifically on the development of a concept of minimal-invasive endodontics, using 3D-Micro-CT scanning, Cone-beam-CT and Environmental SEM, towards new rootcanal preparation and filling techniques. The pathology of external cervical resorption is his favourite study topic. A randomized clinical trial on pulp revascularisation is ongoing. Specific interest goes also to laboratory and clinical research on dental composites, actually focussing on 3D-laser-profiling of clinical wear phenomena and biotribocorrosion. Together with Prof. B. Van Meerbeek, he became in 2003 co-holder of the Toshio Nakao Chair for Adhesive Dentistry. He is (co-)promoter of several doctoral dissertations, and (co-)author of numerous publications (346) together with the Leuven BIOMAT Research Cluster (Hirsch-index of 75).

Session Chair: Paul Abbott

External cervical resorption (ECR) is a complex periodontal and endodontic pathology. The aetiological multifactorial triggers become evident. Treatment options depend on aetiology, resorption stage and extend, understanding of the pathology and ability to approach the lesion in a minimal invasive microscopic way. The objectives of treatment are elimination of the resorptive tissue, sealing of the resultant defect and portal(s) of entry and prevention of recurrence, by limiting the aetiological factors. 

Treatment options include:  

External approach. Keep the tooth vital. 

Flap surgery. Scalpel. Electrocauter.  

Ca(OH)2, MTA, GI, Composite. 

Internal approach. With pulp therapy. 

Vital pulp therapy. 

Pseudocapping. 

Direct pulpcapping. 

Partial pulpotomy. 

Partial pulpectomy. 

Internal approach.  

Consider Gentlewave for cleaning. 

With root canal treatment. 

External & internal combination approach. With root canal treatment. 

Extraction. 

Intentional replantation. 

Decoronation and autologe bridge. 

Adhesive crown splint with Ribbond. 

Implant. 

Autotransplantation of other tooth. 

Monitoring: Watchful waiting. Periodic review. 

The aim of treatment is to retain affected teeth in a healthy and functional state. Success is related to the ability to circumscribe the lesion and seal the defect. Research is required to assess the impact of the size and stage of the lesion (resorptive versus reparative) and the management options on the outcome of treatment. 

External Cervical Resorption lesions that are accessible and therefore amenable to conservative treatment have a good prognosis. However, patients should be advised of the limited evidence on treatment outcomes.

Session Chair: Lise-Lotte Kirkevang

This presentation summarises the key aspects of the narrative review Gulabivala & Ng (2023) Factors that affect the outcomes of root canal treatment and retreatment—A reframing of the principles. International Endodontic Journal, 56: Supplement 2:82-115. The factors potentially affecting periapical healing after root canal treatment are classified into pre-operative, intra-operative and post-operative groups. These categories subsume multiple elements with interactive influences, creating a complex picture, further confounded by some apparently surprising, counter-intuitive and contradictory findings. The apparent data conflicts resolve into a very simple, consistent and plausible picture of how root canal treatment works and the key factors that affect periapical healing. Root canal retreatment is considered in the context of its differences from primary treatment as the majority of factors influencing outcomes are common to both. The exceptional difference is that retreatments have a proportionately reduced probability of healing by virtue of compromised apical root canal ramification access or modified host/infection interactions.Root canal (re)treatment outcomes are dominantly influenced by the nature of prior dynamic host/infection interaction (pre-operative patient factors) and how the direction of this dynamic is influenced by two factors: 1) the active efficacy of the operators’ root canal treatment protocol to sustain a microbial ecological shift (intra-operative treatment factors) and dampen periapical inflammation; and 2) the passive ability of the functional tooth (and its restoration margin) to maintain its integrity to resist infection reversal (post-operative restorative factors). The lecture will also endeavour to demonstrate the application of these principles to clinical practice.

This presentation summarises the narrative review Ng & Gulabivala (2023) Factors that influence the outcomes of surgical endodontic treatment. International Endodontic Journal, 56(Suppl. 2), 116– 139. 

Surgical endodontic treatment encompasses a broad spectrum of procedures, amongst which root-end cavity preparation and filling, retrograde root canal treatment, and through & through endodontic surgery, may be classified under the umbrella term “Root-end surgery”. This presentation will begin with a discussion of the various outcome measures used for root-end surgery and different criteria for classification of periapical healing. It will be followed by detailed analyses of the factors affecting periapical healing outcome. The variations in the pooled periapical healed rates by year of publication will be discussed. The potential pre-operative, intra-operative and post-operative factors explaining such variations will be critically appraised highlighting potential confounding to be considered when analysing such data in observational studies. The presentation will conclude by highlighting the dominant effect of pre-operative periapical lesion with complete loss of buccal plate, quality of root-end preparation, remaining thickness of apical root dentine and restorative status.

Persistent intracanal infection is the main reason for post-treatment apical periodontitis associated with root filled teeth. Therefore, effective and safe removal of the existing filling material is the initial important step to allow thorough cleaning and disinfection of the root canal system. Over the years, a variety of materials and techniques have been used to fill root canals. Hence, there is also a considerable number of mainly laboratory-based studies evaluating different instruments, techniques and supplementary procedures for the removal of these filling materials. In the current literature, great variation exists regarding the methodological tools for visualization and quantification of remaining root filling material, the criteria for sample selection and distribution as well as the technical aspects of retreatment procedures. This lecture aims to present an overview of the various research methods used to assess the efficacy of different removal techniques and to analyse their advantages and limitations. Finally, requirements for an ideal experimental model for future research are critically discussed.

Luxation injuries and other stimuli like caries or restoration may lead to a pulp canal obliteration (PCO). Even though the apposition of tertiary dentine is a sign of a vital pulp, in some cases root canal treatment is indicated in the long term due to apical periodontitis or pulpitis. Depending on the extent of PCO, root canal treatment may be challenging even for experienced and well-equipped endodontic specialists and is associated with a high failure rate. The ‘guided endodontics’ (GE) technique was introduced some years ago as an alternative to conventional access cavity preparation for teeth with PCO and apical pathosis or irreversible pulpitis. Using three-dimensional radiological imaging such as cone-beam computed tomography and a digital surface scan, an optimal access to the orifice of the calcified root canal can be planned virtually with appropriate software. GE is implemented either with the help of templates analogous to guided implantology (= static navigation) or by means of dynamic navigation based on a camera-marker system. GE has emerged as a field of research in the last decade with very promising laboratory-based results regarding the accuracy of guided endodontic access cavities for both static and dynamic navigation. Clinical implementation seems to provide favourable results, too. This lecture shows the indications of GE, explains the procedure step-by-step based on clinical cases and presents advantages and disadvantages of this method. At the end, a short outlook on future developments in this field is given.

The quest for treating diseases through minimally invasive procedures has permeated endodontics, but not without controversy. An increasing number of studies have addressed the “potential” to adopt such minimally invasive procedures in root canal treatment, with the larger goal of conserving tooth tissue for long-term survival of treated teeth. While conservation of tooth structure appears to be a logical and reasonable mechanical goal, does it compromise our biological goals in root canal treatment? There is substantial work on minimally invasive access cavity preparation, but a less explored area is conservative root canal preparation. This talk aims to appraise the current literature on conservative endodontics and raise thought-provoking questions on the futuristic possibilities in this important area in light or our current knowledge of root canal infections, periradicular pathology and host responses in healing of infections.

Endodontic success is achieved not only by obtaining a proper apical seal but also a coronal seal. Coronal leakage is one of the main reasons for long-term failure of endodontically treated teeth.  A pulpless tooth is different to a vital tooth, mainly in terms of remaining tooth structure. Hence, it is the residual dentinal tissue (and its preservation) that mainly dictates the restoration. This is particularly important for severely compromised teeth, where we should accurately choose the best restoration. 

Many techniques are available for the reconstruction and restoration of pulpless decayed teeth. Is a root canal post absolutely necessary? Which core materials should be used? Should a crown be placed after root canal therapy? With modern adhesive dentistry there are two treatment possibilities for anterior and posterior teeth: placamento of a direct restoration or placamento of an indirect restoration.

Adhesive techniques can be used in either approach to achieve coronal restoration which will seal properly. To obtain favourable long-term results, the restoration must protect the tooth against excessive load. The cervical region of the restored tooth is subject to the most stress. We should restore an endodontically treated tooth in the most conservative way possibly minimizing any further tooth structure loss; adhesive techniques offer potential advantages.

AIM: to give indications in this presentation why we will choose either direct or indirect restoration in different clinical situations and the type of corono-radicular restoration procedure that should be adopted

There is a significant amount of data in the literature regarding the loss of teeth that have had root canal treatment and have been restored using both direct and indirect methods. These studies include research on the survival of endodontically treated teeth, such as database and prospective studies, as well as observations of full mouth radiographs taken at different intervals to assess the number of root canal treated teeth present and lost. The results of these studies indicate significant differences, with database studies reporting lower survival rates compared to prospective studies. Additionally, recent data suggests that endodontically treated teeth have shorter survival times when compared to single implants. This presentation will review the available data on the impact of restorations on the survival of root canal treated teeth. It will also present the surprising results of a study that is currently undergoing review, which compares "real life" data to data collected in clinical trials. There are a variety of factors that may impact the survival of root canal treated teeth, including tooth cracks, the volume of tooth structure lost, indirect (partial or full coverage) and direct restorations, CAD-CAM based restoration, and the difference in survival rates between primary and secondary root canal treatments. These factors will be the focus of the presentation.

The technical execution of root canal treatment procedures demands a thorough understanding and knowledge of root and canal anatomy. Over the decades, and with the aid of various research methods such as staining and clearing, 2D radiographic imaging, sectioning procedures, cone beam computed tomography and micro-computed tomography, many laboratory and clinical studies have been undertaken to understand the root and canal anatomy of the human dentition. This has resulted in a tremendous increase in the body of knowledge with a wide range of qualitative and quantitative presentations of the root and canal anatomy. From a researcher and clinician point of view, this lecture aims to provide a critical analysis for the laboratory and clinical research methods in root and canal anatomy studies. In addition, it aims to identify existing gaps and present insights for directions of future research and ways for translation to clinical endodontics.

Outcome studies have repeatedly shown that the apical endpoint of root canal preparation and filling is a determinate factor for the outcome of root canal treatment. Accurate determination of root canal length enhances the efficacy of chemo-mechanical disinfection and prevents over/under instrumentation. Long and short root canal fillings are consistently reported to be associated with higher rates of post-treatment endodontic disease. Although standards for undertaking and reporting diagnostic accuracy studies are available, publications dealing with the determination of root canal working length are highly heterogeneous and describe procedures inconsistently. The aim of this presentation is to critically assess the methodology of working-length publications; the process of planning, performing and analysing such studies will be presented with suggestions to optimise the research methods.

The aim of this lecture is to provide a critical overview of the physical properties (surface hardness, cutting efficiency, bending properties, flexibility, cyclic fatigue resistance) of NiTi instruments. Frequently used experimental models regarding these aspects will be presented and discussed with regard to their strengths and weaknesses. For all these aspects a plethora of experimental models have been described. Based on a critical appraisal and especially taking the appropriate translation of experimental findings to clinical endodontics into account, suggestions for future research based on clearly defined and valid experimental methodologies will be provided.

Up to now, very few attempts have been made to assess, which particular physical properties of NiTi instruments exert an impact on the clinical outcome of root canal treatment. Departure from merely focusing on physical properties and fracture characteristics towards more biological aspects in terms of treatment outcome is essential.

Another research interest is risk assessment and decision-making in dentistry. She is a driving force behind the Scandinavian Research Collaboration (EndoReCo), a collaboration striving to increase the knowledge about the root-filled tooth. As most research of today is based on collaboration rather than on individual achievements, the EndoReCo collaboration aims to provide a nourishing research environment for the current four PhD-students pursuing joint research plans. Dr. Fransson is currently serving on the board of the Swedish Endodontic Society and is a member of the Benefits of Endodontics Committee of the European Society of Endodontology.

Session Chair: Phil Tomson

There are several measures that are, or could be, in use in relation to estimating the outcome of endodontic treatments. It is important to reflect on when and why a certain outcome measure is used; when caring for an individual patient it is obvious that the goal always should be a tooth in a healthy state, that is striving to remove any infection and aim for the tooth to have healthy periapical tissues. For patients in general and for society, it is also interesting to know if endodontic treatments will lead to retention of teeth in a functioning state. From epidemiological studies, with high prevalence of root filled teeth with periapical radiolucencies, it is implied that dentists and/or patients accept the retention of a root filled tooth with persistent apical periodontitis. In conjunction with an endodontic treatment the prognosis is considered and since the prognostic factors seem to be somewhat different depending on whether one is considering for example the outcome 'healthy periapical tissues' or 'tooth survival' they are equally important to know. Factors affecting the outcome 'healthy periapical tissues' probably has to do with removal of infection and reconstituting the barrier to prevent leakage whilst 'tooth survival' is more likely associated with factors outside of the classical endodontic field such as restorability and avoidance of further destruction of tooth substance. The aim of the lecture is to present the current knowledge on survival of endodontically treated teeth and to consider opportunities and obstacles in using the outcome measure tooth survival. At the end of this presentation, the attendee should be familiar with factors related to tooth survival of endodontically treated teeth and appraise the prospects and obstacles in using the outcome measure tooth survival.

Aims
The purpose of this presentation is to evaluate a new system of rotary Ni-Ti instruments to better understand their clinical use.

Learning Objectives
Root canal shaping is a key moment in endodontic treatment. Knowing the anatomy of the canals and the characteristics of the Ni-Ti alloy rotary instruments used in clinical practice allows the clinician to approach canal preparation in a safe and rational way. The use of the new heat-treated alloys has certainly improved the feeling during shaping and despite the considerable more speed of the procedure, the principle that the treatment time is not linked to the shaping time but to the cleaning time still remains valid.

Endodontics is a dynamic branch that synergistically combines a diverse range of materials and instruments, all working together to enhance healing and long-term functional outcomes. Bio-Minimal Endodontics is an emerging paradigm that revolutionizes traditional endodontic practices by focusing on preserving the natural tooth structure and promoting biological healing. By combining biologically driven concepts with cutting-edge technologies and materials, this approach holds the potential to elevate treatment precision, improve patient comfort, reduce treatment duration, and enhance long-term treatment success.   

This lecture aims to discuss the core principles of Bio-Minimal Endodontics, exploring its innovative and simplified techniques, materials, and their applications in achieving successful and sustainable results.  

Nicola M Grande has been Adjunct Professor of Endodontics in the Catholic University of Sacred Heart (2002-2008), from 2009 to 2012 he worked as Researcher in the Department of Endodontics at the University of Rome “La Sapienza”. Since 2013 he is Assistant Professor of Endodontics at the Catholic University of Sacred Heart. His main scientific interests are the preparation of root canals with Nickel-Titanium rotary instruments, the study of anatomy and preparation of endodontic anatomy by micro-computed tomography techniques and the restoration of the endodontically treated teeth with new conservative approach. He has published extensively in international peer-reviewed journals, he is contributor in several books of endodontic interest, member of the Editorial board of international peer reviewed journals and he is lecturing both nationally and internationally as keynote speaker in the fields of endodontics, microsurgery and restorative dentistry. He works in private practice limited to endodontics and microsurgery in Rome – Italy.

Beginning with the holy principles first enunciated by Herbert Schilder almost 50 years ago, this lecture will be focused on the impact of the evolution in mechanical instrumentation and cleaning technologies on the basic principles of chemo-mechanical endodontic procedures. The possibility to save sound tooth structure to improve the mechanical resistance of the crown-root complex, the changes in paradigms regarding the apical preparation and disinfection, the evolution in the irrigation sequences as well as new proposals in the chemistry of cleaning solutions, and the correlation between different physical activations of the irrigants together with the mechanical action of shaping instruments will be analysed. 

The tricky balance between mechanical enlargement of the root canal space and the production of hard tissue debris is a key factor in obtaining a deep cleaning of the pulp space; a minimal average size that permits the penetration of chemicals in endodontic anatomy is required, but in the same time the possible clogging created by the mechanical action itself it’s a risk that should be prevented. The influence of different initial anatomies and physio-pathology of root canals on these factors is another key point that will be addressed in this lecture, together with different possible clinical strategies suggested to manage cleaning and shaping procedures aimed to optimise their action in order to achieve the principles depicted by Herbert Schilder that are still guiding our clinical protocols.

From 1978 to 1980 he attended continuing education courses on Endodontics at Boston University School of Graduate Dentistry. As well as running a practice limited to Endodontics, Dr. Castellucci is Past President of the Italian Endodontic Society, Past President of the International Federation of Endodontic Associations, Active Member of the European Society of Endodontology, Active Member of the American Association of Endodontists. 

He is Assistant Professor of Endodontics at the University of Cagliari and Professor of Micro Surgical Endodontics at the University Federico II of Naples. 

Recently has been nominated Assistant Professor of Endodontics at Boston University, Faculty of the Henry M. Goldman School of Dental Medicine. 

He is a very well-known international lecturer and gave lectures in about 66 different countries all around the world. 

He published more than 60 articles on Endodontics in the most prestigious Endodontic Journals and wrote chapter in several prestigious endodontic textbooks. 

He is the author of the textbook “Endodontics”, now available in Italian and English, with more than 1,600.00 pages and about 80 QR Codes, and is also the author of the new textbook “Micro Surgical Endodontics”, full of illustrations and videos, both edited by EDRA. 

Over the past 20/30 years there has been an incredible explosion of new technologies, new tools and new materials. Amongst these, certainly the most revolutionary events that one remembers are the introduction of the operating microscope and ultrasonic units with their tips. 

The microscope provides a better view, thanks to the magnification and coaxial illumination. 

Ultrasonics, especially with the use of the microscope, allow operations to be performed with a precision that was once unthinkable. 

They have numerous applications, both in non-surgical and surgical endodontics. 

Ultrasonic vibrations can be used to remove a crown, a post, to finish the access cavity, to remove calcifications from the pulp chamber floor. Finding the mesio-palatal canal (MB2) of the upper molars has become extremely easier with the new ultrasonic tips available on the market today: they cut like diamond burs, but at the same time they are much more delicate. The removal of fractured instruments from inside the root canals is now an easier operation, with easier time scheduling and more certainty of predictable results. 

In surgical endodontics, with the use of the new ultrasonic tips, the preparation of the retrograde cavity is done aligned axially with the root canal, the removal of the old root canal filling material, the attainment of a completely cleansed cavity throughout 360 degrees is easier and faster. 

In conclusion, we can certainly state that today the non-surgical or surgical retreatment of endodontic failures gives more predictable results, with higher success rates, thanks to ultrasonic units and tips used under the magnified and better illuminated vision that the operating microscope provides us.
