Speaker: Matthew Davis, D.D.S.|Cracked teeth pose inherent challenges in diagnosis and management and confusion and disagreement abound in our literature. Cracked tooth with radicular extension is a new subclassification of longitudinal tooth fracture, which requires different endodontic and restoration protocols for successful outcomes. An understanding of the nuances of cracked tooth management allows us the ability to help our patients save more teeth.

This review aimed to synthesize current evidence on CT and propose a diagnostic framework.

Krell, DDS, MS, MA|This study evaluated the treatment outcomes and prognostic factors of root canal–treated posterior cracked teeth using the Modified Iowa Index, as published in the Journal of Endodontics. The index enables structured prognostic stratification by integrating crack morphology, periodontal status, radicular crack depth, periapical conditions, occlusal risk, and definitive restoration type. Understanding survival trends and independent risk factors supports evidence-based clinical decision-making and improves long-term tooth preservation in compromised posterior cracked teeth following root canal treatment.

Speaker: Daniel Cerny MUDr., Ph.D.| Immediate adhesive restoration of endodontically treated tooth provides both structural rehabilitation and microbiological isolation to the root canal treated tooth. In the hands of the treating endodontist, it provides both functions on the spot. No insecure period, no risk of reinfection, no need to put rubber dam again. Key elements of such restorations will be provided together with plethora of clinical cases.

Speaker: Samuel I. Kratchman, D.MD |Use of the Piezotome for endodontic microsurgery has become quite popular, especially creating a bone "window" or "lid" to gain better access to areas like mandibular molars with thick cortical bone. It can be technique sensitive to replace those windows securely, allowing for the bone to revascularize and maintain the osteotomy space. This lecture will discuss drawing the patient's blood and centrifuging out platelet-rich fibrin plugs and membranes as well as crushing the bone "window" and mixing it with the serum created from forming the PRF membrane to make "sticky bone", which is sandwiched in between the PRF plugs and covered by the PRF membrane. The latter part of the presentation will focus on treatment planning and case selection for Intentional Replantation, explaining the techniques in detail and showing several clinical cases with follow ups.

Speaker: Jaime J. Silberman, D.D.S., M.S. |Guided surgery has garnered significant interest in our specialty over the past 5 to 7 years. The introduction of dynamic and static navigation has enabled endodontists to perform surgical and non-surgical procedures with greater precision and minimal invasiveness. Complex surgical cases—such as palatal root periapical surgery of maxillary molars and periapical surgery of posterior mandibular teeth—are particularly well-suited for these techniques. However, several questions arise when planning or performing guided surgical procedures: Should the surgery be partially guided or fully guided? Is the case suitable for a guided flapless approach? Does guided surgery offer a real advantage in the given scenario? The purpose of this clinical presentation is to examine both the benefits and limitations of guided surgery, and to discuss the critical decision-making involved in its application.

Speaker: Pierre Wohlgemuth, D.D.S. |Endodontic surgery has seen remarkable improvements in clinical and radiographic outcomes thanks to the development of advanced microsurgical techniques and instruments. However, while these procedures effectively address apical lesions, they can sometimes lead to unintended soft tissue issues such as recession, papilla loss, and scarring. As aesthetics become increasingly important in patient care, achieving optimal hard tissue results is no longer enough; successful soft tissue management is equally critical to ensure a satisfying outcome. In this presentation, Dr. Wohlgemuth, will guide you through pre-operative assessment and critical steps of endodontic surgery with a focus on enhancing aesthetic outcomes. The lecture will cover incision design, flap management, and the selection of suture size, type, and technique. Through a series of clinical cases, Dr. Wohlgemuth will illustrate how mastering these techniques can significantly improve the aesthetic results of your endodontic surgeries.

Speaker: Ji Wook Jeong, D.MD, M.S.D. |In complex clinical scenarios, some dentists might just go straight to suggesting an extraction and implant. However, many patients still express a strong preference for saving their natural teeth—whether due to personal values, medical conditions, dental anxiety, or financial and philosophical reasons. When non-surgical root canal treatment is not feasible, endodontic microsurgery may offer a useful alternative. This presentation explores a comprehensive approach to case selection and treatment planning in endodontic surgery. Beyond evidence-based principles, a novel stepwise clinical sequence developed by the presenter will be introduced to guide decision-making in challenging cases. Clinical examples will include separated instruments, radicular cysts, root resorption, radicular grooves with periodontal involvement, canal transportation, perforations, and suspected vertical root fractures. Attendees will gain practical strategies for preoperative evaluation such as risk assessment, and surgical planning to achieve predictable, patient-centered outcomes.

Perez, DDS, MSc, PhD|Postoperative pain remains a critical concern in endodontic treatment, influenced by multiple factors, including the choice of root canal sealer. Calcium silicate–based sealers like NeoSealerFlo offer biocompatibility and bioactivity, while resin-based sealers such as AH Plus are widely regarded as the gold standard in endodontics. This study aimed to compare postoperative pain and sealer extrusion between these two materials in a large-scale clinical setting.
