Description: For generations, endodontists have been taught that the goal of obturation is to hermetically seal the root canal system-blocking microbial reinvasion and promoting periapical healing. But in today's world, where social media often glorifies radiographic aesthetics over biological function, have we drifted from our true purpose? In this presentation, Dr. Allen Ali Nasseh takes attendees on an inspiring journey through the history of obturation-from early scientific principles to modern techniques-reframing its core purpose around biology and mechanics rather than imagery. Looking ahead, emerging technologies promise greater precision and customization, while regenerative approaches may redefine the very goals of endodontics. Dr. Nasseh challenges clinicians to embrace these innovations in light of the disease model's established scientific principles, while resisting the pull of radiographic artistry.By exploring obturation's past, assessing its present, and projecting its future, this session equips attendees with evidence-based strategies to achieve functional, durable seals-ensuring clinical success in an era where truth must prevail over marketing trends.
Learning Objectives:
- Recognize how shifting philosophies have influenced clinical decision-making over time.
- Become familiar with the evolution of Endodontic obturation materials and techniques from the past to the present.
- Explore emerging technologies and regenerative approaches that may redefine endodontic goals.

Description:
Since the launch of calcium silicate-based bioceramic sealers, the popularity of its clinical applications has grown dramatically in the last 16 years. Almost 50% of the AAE members and 27% of the ADA members reported using this type of sealer, which have surpassed resin-based sealers and it has become the most widely-used sealer type among endodontists.
Due to the increase of the interest of these sealers, several companies have developed its own version of a calcium silicate-based bioceramics products (sealer and putty). The majority of these products are pre-mixed which simplify the clinical use. While the verity of these products in the market increase considerably in the last 5 years, the number of clinical and laboratory studies on the latest products have been limited. Although many of them are called bioceramic sealers, there are many variation, among them, their chemical components, sealability, biological activities and more.
In this presentation we will compare the most popular pre-mixed bioceramic products in the market and show their clinical applications and obturation techniques.
Learning Objectives:
- Describe the endodontic hydraulic bioceramic cements and their clinical interactions
- Update and compare the traditional and new bioceramics materials available on the market
- Demonstrate tips and tricks on how to use these materials in different clinical cases

Description: A growing number of practitioners use calcium silicate-based sealers in root canal therapy. If the primary treatment has failed, non-surgical retreatment is considered the primary treatment option. However, the retreatability of cases incorporating a calcium silicate-based sealer is debatable as a specific, clinically acceptable solvent has yet to be developed. There are also few outcome studies concerning retreating these cases. This presentation will critically review the current studies addressing retreatment and retreatability of cases incorporating a calcium silicate-based sealer, and discuss methods to retrieve calcium silicate based-sealers combined with gutta-percha cones using different solutions, solvents, primary rotary files, retreatment designed files, heat-treated or non-heat-treated files, ultrasonic or sonic irrigation, in both straight or curved canals exhibiting short, flush with the apex, or overextended obturation.
Learning Objectives:
- Compare the efficacies of different solvents/irrigants and ultrasonic/sonic irrigation for retreatment cases incorporating a calcium silicate-based sealer
- Evaluate the efficacies of different rotary files for retreatment cases incorporating a calcium-silicate sealer
- Design specific retreatment strategies for clinical scenarios involving straight or curved canals, and patent or non-patent canal cases

Course Description:
This webinar gets to the root of obturation difficulties faced by many endodontists. A discussion of bioceramic sealers will highlight a paradigm shift in endodontics—a shift from “gutta-percha based obturation” to “sealer-based obturation”. With sealer-based obturation in mind, the lecture will review strategies for selecting sealers (including viscosity), placement techniques, and check-points to dense, predictable obturation. The aim is to inform attendees of obturation strategies they may implement in their practices to make the most of bioceramic sealers’ benefits—without the need for warm gutta percha!
Learning Objectives:- Discern between different sealer types, consistencies, and placement strategies
- Replicate strategies for predictable obturation using cold techniques, including hydraulic condensation (aka single cone) and cold lateral
- Implement strategies to obturate canal intricacies—such as internal resorption and isthmuses—using cold obturation techniques
