Description: Selective root canal retreatment (sRCR) offers a minimally invasive alternative to full retreatment by addressing only diseased roots while preserving healthy ones. This webinar will explore the clinical efficacy, benefits, and risks of sRCR, with a focus on tooth preservation, fracture resistance, and cost-effectiveness. Participants will gain practical insights into integrating this philosophy into daily practice.
Learning Objectives:
- Describe at least two key findings on the clinical efficacy of selective root canal retreatment (sRCR) compared to full retreatment.
- Analyze how sRCR contributes to tooth preservation and fracture resistance
- Compare the relative cost-effectiveness of sRCR versus full root canal retreatment, identifying at least one patient-centered and one practice-centered implication.

Description: Instrument separation remains one of the most complex complications in endodontic practice. This course explores both the science behind file fracture and the innovations designed to prevent it. Attendees will gain a clear understanding of the mechanical and metallurgical factors that lead to separation. The microstructural behavior of NiTi alloys-phase transformations, proprietary heat treatments, and advanced surface processing-will be explained in practical, clinical terms. Equally important, participants will learn predictable strategies for managing separated instruments. Techniques such as CBCT-guided planning, ultrasonic troughing, microtube and loop systems, bypassing, and minimally invasive access will be presented with emphasis on dentin preservation and outcome success. Decision-making protocols will guide clinicians in evaluating case difficulty, preserving dentinal structure, and identifying when surgical intervention is warranted. Designed for endodontic specialists, this evidence-based lecture combines science with practical guidance to equip participants with the skills and confidence to manage instrument separation predictably with minimally invasive access approaches.
Learning Objectives:
- Discuss in-depth the microstructure of Nickel-Titanium (NiTi) alloys and how heat treatment enhances their flexibility and strength, reducing the risk of file fracture
- Gain expertise in advanced techniques and tools, including ultrasonics and retrieval kits, to access and remove separated files effectively using minimally invasive, tooth-preserving approaches.
- Develop strategies to minimize the risk of file breakage during root canal treatment, including proper instrument handling and the use of heat-treated NiTi files.

Description: The endodontic community has seen widespread adoption of bioceramic sealers throughout the past 15 years due to their unique biocompatible properties. Although modern root canal treatments are completed with a high level of success, there is an inherent need for retreatment procedures. Unlike traditional sealers, however, bioceramic materials have presented the challenge of complete removal during root canal retreatment. Until now, the focus of retreating bioceramic obturations has been on mechanical removal with or without adjunctive solvent use. These techniques have mixed evidence-based support. This presentation will explore modern retreatment techniques including mechanical activation as well as evaluating various solvents and their impacts on root canal retreatment.
Learning Objectives:
- Review the goals of modern root canal retreatment procedures
- Discuss available solvents and techniques aimed at bioceramic retreatment
- Evaluate current scientific evidence on retreatment of bioceramic sealer-obturated canals

Description: The decision to treat or extract a tooth in the esthetic zone is one of the more complex decisions that a practitioner must make. It is a test of the team’s knowledge and ability to reach the ultimate goal of an esthetic and functional restoration that will last for years to come. All this must be done with the patient’s emotional and financial status considered. This session will focus on the latest challenges in diagnosing endodontically treated teeth that may require surgery to assist in dental dam isolation, apical surgery and/or intentional replantation. This will be both a “why to” presentation focusing on the decision-making process and a “how to” presentation.
Learning Objectives:
- Obtain a 3D diagnostic database for successful endodontic treatment planning and case acceptance.
- Review Digital Transformation and how we collaborate through new encrypted data opportunities.
- Identify the benefits of collaborative studies

Description: Dealing with obliterated root canals presents a significant challenge in endodontic practice, often leading to treatment difficulties, stress and compromised outcomes. This presentation aims to equip endodontists with essential knowledge of four key principles required to effectively map dentine and localize obliterated root canals. By implementing these principles, endodontists can lower the risks associated with missed anatomy, feel confident when working in highly calcified teeth, and navigate the challenges associated with complex root canal anatomy in a predictable way.
Learning Objectives:
- List 4 simple rules to locate canals in challenging endodontic cases.
- Describe the importance of dentinal color changes when locating canals.
- Minimize the occurrence of missed anatomy during treatments/retreatments.

Description: As bioceramic sealers are growing in popularity, there is also a rise in the number of cases obturated with bioceramic sealers that need to be retreated. One important goal during retreatment is to eliminate the etiology of persistent disease through the complete removal of the root canal content including the existing root-filling material. Compared to traditional sealers, set bioceramic sealers may be more difficult to remove or bypass with instruments due to their unique physical properties. There is also a lack of effective solvent for set sealers, therefore creating potential difficulties in retreatment. Controversies exist in the literature regarding the effectiveness of bioceramic sealer removal. This presentation will provide a comprehensive review of the available evidence on the retreatment of bioceramic sealer-obturated canals and discuss the clinical tools and techniques to facilitate bioceramic sealer removal.
Learning Objectives:
- Describe the principles of non-surgical root canal retreatment.
- Describe the available solvents and techniques for the removal of bioceramic sealers.
- Discuss the existing scientific evidence on the retreatment of bioceramic sealer-obturated canals.

Description: The frustration and difficulties related with the removal of separated instruments are well known. The presented file retrieval technique has the approach to be as minimal invasive as possible and more predictable in terms of time management, costs and outcome. A new troughing technique using sonic instead of ultrasonic reduces the time needed to expose the fractured instrument and minimizes the risk of a second fracture of the instrument as well as heat induced tissue damage. A specially developed wire with higher tensile strength and reduced elongation as well as a new ball bearing tensioning mechanism allows to remove even ingrained files using a strict push and pull movement. The device and technique will be described in detail and a step by step tutorial will be presented during this lecture. Several cases will be shown to show the possibilities of this file retrieval technique.
Learning Objectives:
- Evaluate the risks and benefits of the retrieval of broken files.
- Discuss the advantages of the presented technique.
- Evaluate the clinical use of the presented modifications in the lasso technique.
