Clinical Endodontics Symposium 2026

Abstract

This lecture will explore how digital workflows can enhance the endodontic management of challenging anterior teeth. Clinical applications will include the treatment of traumatized teeth, with a particular focus on tooth autotransplantation, calcified canals, and regenerative endodontic procedures (revascularization). The use of digital technologies in the management of developmental anomalies affecting the anterior dentition will also be discussed.

Learning Objectives

• Understand the role of digital technologies in endodontic diagnosis, planning, and treatment in challenging anterior teeth. 
• Apply digital workflows to improve the precision of tooth autotransplantation. 
• Manage calcified canals and complex endodontic anatomy using digital tools. 
• Recognize the role of digital technologies in regenerative endodontics (revascularization).

Abstract

No two root canal systems are alike, which is why endodontists plan every case in detail. Yet for many practitioners anaesthesia remains one technique: the same injection, the same cartridge, the same site. This lecture argues that the anaesthetic technique is not a gesture but the consequence of endodontic planning, and shows what changes when it is treated that way, with clear guidelines for each endodontic situation: where to inject, which solution and how much, all decided before the first drop.

The inflamed pulp is the most difficult tissue in the mouth to anaesthetise, for three documented reasons: the local fall in tissue pH, the altered expression of sodium channels in nociceptive fibres, and sensitisation of the trigeminal system. The lecture reviews what the literature reports for the inferior alveolar nerve block in symptomatic irreversible pulpitis, its success rate and its time to onset, and why a numb lip says nothing about a numb pulp. It then examines what actually rescues a failed block, and at what cost, including the limits of the periodontal ligament injection.

From there the lecture builds the planning sequence. Which tissues have to be anaesthetised for the procedure planned, which in endodontics means three territories for a single tooth. Then where to inject, which solution, how much, how fast, and with what. Each answer constrains the next, and the choice of instrument comes last. Intraosseous delivery is examined within that framework, with its onset data, its documented limits, its contraindications, and the studies that point the other way.

The lecture closes on worked clinical situations: emergency pulpotomy, complete treatment of a mandibular molar, acute apical abscess, retreatment, necrotic pulp, and surgical endodontics, each with its own anaesthetic answer.

Learning Objectives

• Explain the three mechanisms by which pulpal inflammation reduces the efficacy of local anaesthesia: tissue pH, sodium channel expression, and trigeminal sensitisation.
• State the reported success rate and time to onset of the inferior alveolar nerve block in symptomatic irreversible pulpitis, and explain why lip numbness is not an indicator of pulpal anaesthesia.
• Compare the supplemental techniques available after a failed block, including their effectiveness, their duration and their documented risks.
• Determine which territories must be anaesthetised for a given endodontic procedure, and derive from them the required depth, extent and duration of anaesthesia.
• Apply the planning sequence (where, what, how much, how fast, with what) to typical endodontic situations, including those where intraosseous anaesthesia is contraindicated.

Abstract

Root canal treatment can be challenging and stressful. This lecture aims to give clinicians practical tools to make treatment simpler, improve efficiency and reduce stress, while following key biological and clinical principles.

We will discuss how magnification and ultrasonic tips can help with access preparation and canal location. We will explain canal instrumentation in three stages: the coronal, middle and apical thirds. This approach gives each stage a clear purpose and helps clinicians work step by step. We will also discuss instrument motion and how it affects canal shaping.

Finally, we will present single-cone obturation with a bioceramic sealer, including the clinical steps, advantages and limitations.

Clinical cases will show how to bring these steps together in daily practice. The aim is to help clinicians understand what to do, how to do it and why, so they can treat patients with more confidence and less stress.

Learning objectives

By the end of the lecture, participants should be able to:

• Explain how a clear treatment sequence can help simplify endodontic care and reduce stress.
• Discuss the use of magnification and ultrasonic tips for access preparation and canal location.
• Describe how to prepare the coronal, middle and apical thirds in a step-by-step sequence.
• Explain the role of instrument motion in canal shaping.
• Describe the steps of single-cone obturation with a bioceramic sealer and discuss its advantages and limitations.

Abstract

Advances in digital technology are transforming the way clinicians diagnose, plan, and manage complex endodontic cases. From intricate root canal anatomy to compromised retreatment cases with procedural errors, technology-enhanced workflows have significantly improved precision, efficiency, and treatment predictability.

This lecture will present a practical, evidence-based approach to managing complex primary treatments and retreatments through the integration of advanced technologies, including CBCT & Artificial Intelligence aided imaging, dental operating microscopy, ultrasonic instrumentation, laser irrigation solution activation and guided endodontic techniques. Emphasis will be placed on the diagnosis and management of challenging anatomical variations, as well as the correction of common procedural complications such as missed canals, separated instruments, perforations and inadequate previous treatments.

Through a series of clinically documented cases, participants will gain practical insights into treatment planning, decision-making and minimally invasive strategies that preserve tooth structure while maximizing long-term outcomes. The lecture aims to demonstrate how technology-enhanced endodontics enables clinicians to transform complex clinical challenges into predictable, functional and biologically sound treatment outcomes.

Abstract

Contemporary endodontic retreatment represents one of the most challenging aspects of clinical endodontic practice, requiring a combination of accurate diagnosis, biological understanding, advanced clinical skills, and decision-making ability. Failures in root canal treatment may arise due to persistent microbial infection, missed anatomy, procedural errors, inadequate obturation, coronal leakage, or restorative complications. Successful management of such cases demands a systematic and evidence-based approach. 

This lecture aims to provide a comprehensive overview of retreatment strategies in modern endodontics, with emphasis on failure analysis, case selection, retreatment protocols, and clinical decision-making. The presentation will discuss the role of contemporary diagnostic tools, including Cone Beam Computed Tomography (CBCT), magnification, and illumination, in identifying causes of endodontic failure and improving treatment outcomes. 

Clinical protocols involving removal of previous obturation materials, management of separated instruments, bypassing ledges, negotiation of calcified canals, and management of perforations will be explained through clinical cases and procedural demonstrations. The lecture will further highlight the importance of conservative dentine preservation, irrigation strategies, and three-dimensional disinfection during retreatment procedures. 

Evidence-based concepts related to prognosis, healing outcomes, and long-term success will also be discussed. Emphasis will be placed on practical clinical tips that can be incorporated into routine practice by general practitioners and specialists alike. 

Through clinical cases and scientific discussion, participants will gain a deeper understanding of retreatment principles and learn strategies to improve predictability and clinical success in complex endodontic scenarios.

Learning Objectives

• Discuss the common causes and classifications of endodontic treatment failure.
• Explain the role of CBCT and magnification in diagnosis and retreatment planning.
• Demonstrate appropriate strategies for removal of previous root canal filling materials during retreatment.
• Discuss the management of procedural mishaps including separated instruments, ledges, and perforations.
• Explain evidence-based protocols for improving disinfection and obturation outcomes during retreatment.
• Demonstrate clinical decision-making in selecting cases suitable for nonsurgical retreatment versus surgical intervention.
• Discuss prognostic factors influencing periapical healing and long-term retreatment success.

Abstract

Modern endodontics faces a persistent paradox: the necessity of achieving high-level clinical precision within increasingly constrained treatment timelines. The FKG 4D Solution redefines this balance by integrating the four essential pillars of root canal therapy—shaping, equipment, irrigation, and obturation—into a singular, harmonized workflow designed to respect the 3D complexity of the root canal system across the temporal dimension of the procedure.

Central to this workflow is the XP-4D shaping system, which utilizes adaptive-core technology and multi-stage heat treatment to conform to the natural, often non-round, morphology of the canal. Unlike traditional NiTi systems that impose a standardized shape, the XP-4D acts as a "Time Weaver," expanding and contracting within the canal to ensure maximum wall contact and minimal dentin stress. This is supported by the Rooter X4000, a high-speed brushless motor that provides the specific kinetic energy required for these adaptive files to perform optimally.

To complete the 4D cycle, the workflow incorporates Dual Rinse® HEDP, an all-in-one irrigation solution that combines chelation and disinfection to streamline the cleaning phase, and TotalFill® bioceramic technology for a predictable, single-cone obturation. Attendees will discover how this unified system minimizes procedural steps and mental load while maximizing anatomical accuracy. By shifting from fragmented protocols to the 4D Solution, clinicians can achieve faster, safer, and more biological outcomes that truly honor the natural tooth structure.

Learning Objectives

By the end of this presentation, participants will be able to:

• Deconstruct the 4D Concept: Explain the synergy between  anatomical mapping and the "4th dimension"—the dynamic behavior of instruments and fluids within the canal during treatment.
• Master Adaptive Instrumentation: Describe the metallurgical properties of the XP-4D file and how its "adaptive core" allows it to expand within non-round canals to clean areas traditional round files cannot reach.
• Optimize High-Speed Kinetics: Identify the clinical rationale for using the Rooter X4000 at high speeds to maximize the turbulence of irrigants and the mechanical efficiency of adaptive files.
• Simplify the Disinfection Phase: Integrate Dual Rinse® HEDP into their daily practice to achieve "continuous chelation," effectively removing the smear layer while significantly reducing chairside time.
• Implement Bioceramic Seal: Execute a synchronized obturation protocol using TotalFill BC sealer, ensuring a biocompatible, dimensionally stable seal that complements minimally invasive preparations.

Abstract 

Bioceramic materials have transformed endodontics by combining excellent biological properties with advanced clinical versatility. Their bioactivity, biocompatibility, and sealing ability make them ideal for achieving 3D obturation, repairing perforations, and managing open apex cases. Recent advancements in obturation materials and evidence-based protocols have addressed limitations of traditional gutta-percha, which lacks adhesive properties and may leave microspaces prone to reinfection. Bioceramic sealers provide superior adaptation to canal walls, dimensional stability, and potential chemical bonding with dentine, supporting a true monoblock concept, while bioceramic putty extends applications to challenging cases through inducing hard tissue formation, including perforations, open apices and regenerative procedures. The quality of obturation can be reliably assessed clinically and radiographically, including with CBCT imaging. This session will explore practical techniques using bioceramic sealers and putty, emphasising their role in enhancing treatment predictability, simplifying procedures, encouraging periapical healing and supporting long-term endodontic success even in teeth with extensive pathologies. Attendees will gain insights into integrating these materials into routine and complex cases, highlighting the synergy of modern materials, minimally invasive approaches, and clinical expertise to ultimately shape the future of biologically driven endodontics. 

Learning Objectives

• Understand the biological and physical advantages of bioceramic materials. 
• Apply bioceramic sealers for predictable 3D obturation in all root canal cases. 
• Utilise bioceramic putty in challenging scenarios, including perforations and open apices. 
• Assess obturation quality using clinical and radiographic methods, including CBCT. 
• Incorporate bioceramic-based strategies to improve long-term RCT.

Digitally guided workflows will also be explored, highlighting their potential to support more conservative, efficient, and predictable restorative treatment.

Learning Objectives

• Understand the key factors influencing the restoration of the endodontically treated tooth. 
• Select the most appropriate restorative strategy for each clinical situation. 
• Recognize the role of remaining tooth structure, ferrule, cuspal coverage and adhesive strategies in achieving predictable outcomes. 
• Explore how digitally guided workflows can enhance the planning, execution and predictability of restorative procedures.

Abstract

The widespread adoption of bioceramic materials has significantly advanced contemporary endodontic practice by enhancing the quality of root canal obturation and expanding treatment options for complex endodontic conditions. Owing to their superior biocompatibility, bioactivity, dimensional stability, and sealing ability, bioceramic sealers and repair materials have become integral components of minimally invasive and biologically driven endodontic therapy.

This workshop provides an evidence-based overview of the clinical applications of bioceramic sealers and putty materials, with emphasis on their role in three-dimensional hydraulic obturation and root repair procedures. Participants will review the biological rationale, material properties, clinical indications, and current protocols for predictable use of bioceramic materials in routine and challenging endodontic cases. Special focus will be placed on the management of complex root canal anatomy, apical splits, root perforations, open apices, and internal resorption defects, together with techniques for the combined use of bioceramic sealers and putty to optimise treatment outcomes.

The workshop incorporates extensive hands-on training, enabling participants to perform three-dimensional hydraulic obturation, bioceramic obturation of apical splits, perforation repair, apical barrier formation in immature teeth, management of internal resorption, and clinical manipulation of bioceramic sealer and putty. Upon completion, participants will have acquired the scientific knowledge and practical skills necessary to integrate contemporary bioceramic protocols into daily endodontic practice, thereby improving the predictability of root canal obturation and biologically based root repair procedures.

Abstract

From Canal to Crown is an intensive hands-on course designed to provide participants with a complete and predictable approach to modern endodontic treatment and the subsequent restoration of the endodontically treated tooth.

The course is structured around a continuous “explain → demonstrate → perform” methodology. Theoretical concepts are kept concise and are immediately followed by practical application on endodontic training teeth, allowing participants to develop their skills under direct supervision and receive immediate feedback throughout the course.

The first part focuses on access cavity preparation and canal location, with particular attention to tooth-specific access cavity design and anatomical principles. Participants will then review working length determination, canal negotiation, glide path creation and preflaring before applying these concepts during hands-on instrumentation.

The course will subsequently address the fundamental principles of mechanical canal preparation, including instrument selection, preparation sequence and maintenance of the original canal anatomy. Particular emphasis will be placed on the management of curved and calcified canals, including understanding the risks associated with canal curvature, selecting appropriate instruments, negotiating challenging anatomy and preventing instrument separation.

Participants will then integrate all the concepts covered during the course by performing a complete endodontic treatment from A to Z, including access, canal negotiation, working length, glide path, instrumentation, irrigation and obturation using a single-cone hydraulic condensation technique with bioceramic sealer.

The final stage focuses on the transition from endodontics to restorative dentistry. Participants will evaluate the remaining tooth structure and perform a conservative preparation for an indirect adhesive restoration, with emphasis on preparation design, occlusal considerations and preservation of sound tooth structure.

The course aims to provide practical skills, clinical strategies and predictable protocols that participants can immediately incorporate into their daily practice.
