Description: 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.
At the conclusion of this article, the reader will be able to:
- Explain the value of the Modified Iowa Index for assessing prognosis and predicting tooth survival in posterior cracked teeth after root canal treatment.
- Identify independent risk factors associated with endodontic failure, including Age, Probing depth ≥ 5 mm along the crack, Radicular extension ≥3 mm, Presence of periapical lesion, Multiple crack lines, Absence of occlusal splint in patients with parafunctional habits, Restoration with onlay or resin composite.
- Interpret outcome and survival patterns to guide post-endodontic treatment planning, including selection of definitive restoration and occlusal stress control to optimize long-term success.

(C) (ENDO), Dip ABE|The cornerstone of evidence-based decision-making in endodontics relies on the critical analysis of relevant and methodologically rigorous studies. Understanding prognostic outcomes in contemporary endodontics is essential for making informed treatment choices. However, studies on nonsurgical endodontic initial treatment and retreatment demonstrate variability, partly due to outdated practices that do not reflect current standards of care. Modern endodontics has undergone significant evolution with advancements in tools, materials, and technologies. This contemporary armamentarium allows clinicians to manage complex anatomical and pathological challenges with greater precision and predictability, marking a clear departure from conventional methods. These innovations underscore the importance of integrating state-of-the-art equipment and techniques into everyday clinical practice. This webinar aims to provide a comprehensive and up-to-date review of contemporary nonsurgical endodontic initial treatment and retreatment by examining robust research to understand expected outcomes and identify key prognostic factors. The primary objective is to equip clinicians with the knowledge required to make informed decisions, ultimately contributing to improved long-term outcomes in endodontic care.

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: 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: 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.
