Description: The management of inflamed or injured dental pulp remains a core challenge in endodontics. Conventional root canal therapy controls infection but eliminates the pulp's regenerative capacity. Regenerative endodontic procedures now aim to preserve or restore vitality, with extracellular vesicles (EVs) emerging as a promising cell-free, immunomodulatory, and pro-regenerative approach. This presentation will highlight advances in EVs derived from stem cells of the apical papilla (SCAP) for pulp repair. We will review preclinical and translational evidence showing how EVs modulate inflammation, support angiogenesis and neurogenesis, and activate resident progenitors. Particular attention will be given to their cargo-specialized pro-resolving mediators, growth factors, and miRNAs-and its integration into smart biomaterials for controlled delivery.Endodontists will gain perspectives on how EV-based therapies could complement or even replace cell-based regeneration. Practical issues of sourcing, safety, and clinical translation will also be discussed. EVs represent a paradigm shift: from removing the pulp to enabling its healing.

Learning Objectives:  

• Describe the biological functions and therapeutic potential of extracellular vesicles (EVs) derived from dental stem cells in the context of pulp regeneration.
• Compare EV-based strategies with current regenerative endodontic protocols in terms of feasibility, clinical integration, and future applicability.
• Evaluate the mechanisms by which EVs modulate inflammation and promote tissue repair in the pulpal microenvironment

Description: Navigating calcified root canals poses a significant challenge in endodontics, increasing the risk of procedural errors, such as perforations and excessive tooth structure loss. This lecture will explore the evolution of technology from static guided endodontic techniques to the precision of dynamic navigation systems. Static guides, which are fabricated from a cone-beam computed tomography (CBCT) scan, offer high accuracy for root canal localization by providing a physical template for drilling. However, we will also discuss the limitations of static guides, such as their inability to be adjusted intraoperatively and the need for a separate physical template. This session will then introduce Dynamic Navigation Systems (DNS) as the next step in this technological progression. Unlike static guides, DNS provides real-time 3D guidance, enabling on-the-fly adjustments during the procedure and eliminating the need for a physical template. We will compare the advantages of both approaches, examining how dynamic navigation can significantly reduce substance loss compared to freehand methods and improve efficiency for less-experienced clinicians. This lecture will provide a comprehensive understanding of the strengths of each method and how its application can lead to more predictable and successful outcomes in managing complex calcified anatomies.

Learning Objectives:  

• Compare and contrast the clinical applications, accuracy, and efficiency of static guided endodontics versus dynamic navigation systems for locating calcified canals.
• Evaluate the trade-offs between static and dynamic guidance, including procedural time, the ability to make real-time adjustments, and the reliance on operator skill.
• Analyze how the progressive adoption of these digital technologies, from static guides to dynamic navigation, reduces tooth substance loss and enhances precision during endodontic access preparation.

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: This presentation explores the biological relevance of filling lateral canals, grounded in histologic evidence and clinical observations. In the initial phase, the pulp's histological response to bacterial invasion is described. As bacteria colonize the necrotic tissue near the pulp chamber, an inflammatory response develops, while surrounding tissues remain uninflamed. Over time, with or without symptoms, necrosis progresses beyond the root canal orifices, and bacterial biofilms form along canal walls and anatomical complexities. When degeneration involves lateral canals, localized inflammation occurs, typically milder toward the periodontal ligament due to its rich blood supply. Eventually, biofilms may also form in these areas and, in some cases, extend beyond the root canal system, leading to extraradicular infections. The effectiveness of current cleaning protocols and modern devices in removing vital or necrotic tissue from lateral canals is critically evaluated through extensive histological studies on human specimens. It is shown that complete debridement is unachievable, and that forcing obturation materials into lateral canals does not equate to meaningful or effective filling. The discussion is supported by clinical cases and videos, offering a biologically and histologically informed perspective on whether filling lateral canals contributes to healing and long-term success.

Learning Objectives:  

• Describe the histological response of the pulp and periapical tissues to bacterial invasion, including the formation of biofilms within lateral canals.
• Evaluate the limitations of current endodontic techniques in cleaning and effectively filling lateral canals, based on histological evidence.
• Assess the clinical significance of lateral canal involvement in endodontic infections and healing outcomes, with a biologically informed perspective.

Description: Vital pulp therapy (VPT) plays a crucial role in managing mature permanent teeth with pulp exposure or inflammation, offering a less invasive alternative to root canal treatment. The decision on when and how to perform VPT depends on the degree of pulp involvement, the tooth's vitality, and clinical symptoms. Key VPT options include direct pulp capping, partial pulpotomy, and full pulpotomy, each with specific indications based on the extent of pulpal inflammation. Recent advancements in biomaterials, mineral trioxide aggregate and other bioceramic materials, have improved treatment outcomes by promoting pulp healing and reducing the risk of failure. Hence, these treatment modalities are emerging as promising treatments for maintaining tooth vitality in children and adults. Proper case selection, strict asepsis, using biocompatible materials and good coronal seal are mandatory for success. This presentation reviews the past, present and future of VPT along with the current VPT options, emphasizing the importance of diagnosis, material selection, and individualized treatment planning to achieve optimal long-term outcomes in younger and adult patients.

Learning Objectives:  

• Identify the indications and contraindications for VPT
• Evaluate the prognostic factors influencing treatment outcomes, including pulp status, restorative seal, and microbial control.
• Interpret current evidence-based guidelines and literature supporting the use of VPT
