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.

Speaker: Zameera Fida, D.M.D.|Management of immature necrotic permanent teeth is complicated for many reasons. The treatment options vary depending on the etiology of pulpal and periradicular disease. In addition, the behavior of the patient may hinder the endodontist’s ability to provide ideal treatment. Finally, reimbursement rates and lack of coverage for certain services may not allow for treatment of the immature permanent tooth to become part of a financially sustainable endodontic practice. The purpose of this webinar is to highlight some of these challenges and offer practical solutions to allow for treatment of the pediatric patient to become a more viable option for your practice.

Speaker: Justin Kolnick, DDS|Bacterial testing of root canal systems in patients has traditionally presented with many difficulties. The culture technique never gained wide acceptance as the procedure is arduous and time consuming. DNA-based identification such as polymerase chain reaction suffers from high false positive readings by detecting DNA from dead bacterial cells. A newly introduced ATP assay detection method provides rapid identification of organic residues in root canal systems by detecting ATP, as well as its degradation products ADP and AMP, using a combination of luminescent reactions. The resulting luminescence is measured and displayed as a 0 – 100 Endoscore, with low scores indicating less cellular (bacterial) contamination. The ability to acquire results within 10 seconds can have significant ramifications in endodontics by allowing dentists to assess and modify cleaning and disinfection protocols in real time. Extrapolating data from research in extracted teeth, with artificially created biofilm, to clinical treatment of patients is complicated with potential inaccurate and erroneous inferences. This presentation will review the ATP assay detection method and present data illustrating how this method can be used to validate an Er,Cr:YSGG laser-assisted endodontic protocol for the cleaning and disinfection of root canal systems.
