Speaker: Pierre Wohlgemuth, DDS|Cemental tear is an underrecognized cause of localized periodontal breakdown and persistent periapical findings that can closely mimic vertical root fracture, endo–perio disease, or “failed” endodontic/periodontal therapy. Because the clinical and radiographic picture may appear nonspecific, the condition is often missed until late in the disease course, sometimes becoming evident only after surgical exploration or extraction of a non-healing tooth. This session presents a practical, step-by-step approach to identifying cemental tear in everyday practice, emphasizing pattern recognition, targeted imaging interpretation, and diagnostic decision-making to reduce unnecessary retreatment. Participants will review proposed mechanisms and risk factors, the spectrum of clinical and radiographic manifestations, and an updated framework for categorizing tears to guide treatment selection. Management options, including non-surgical, periodontal, and endodontic-surgical strategies, will be discussed, with attention to case selection, expected healing, and prognostic indicators. Real-world cases will illustrate how early recognition can shift treatment planning and improve outcomes.

Learning Objectives:
- Explain etiologic mechanisms / causes of cemental tear.

Speaker: Amir Azarpazhooh, D.D.S., M.SC., F.R.C.D. (C) (DPH), CERT. ENDO., PhD, F.R.C.D. (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 However, studies on nonsurgical endodontic initial treatment and retreatment demonstrate variability, partly due to outdated practices that do not reflect current standards of care.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: Spyros Floratos, DMD|Vertical Root fracture (VRF) is a longitudinally oriented complete or incomplete fracture of the root that originates from its apical end and propagates coronally and is defined as one of the crack types. According to the literature, VRF is the third most common reason for extraction of an endodontically treated tooth. Prognosis of vertically fractured teeth is usually questionable or poor, oftentimes leading to extraction. Concerning incomplete VRFs, several surgical techniques have been described. A predictable microsurgical technique involves elimination of the fractured part of the root with simultaneous preservation of the healthy root length and regenerative technique to enhance bone reformation. This technique can ultimately save the teeth, obtain periradicular bone healing and restore functionality. The purpose of this presentation is to highlight microscopic surgical preservation for teeth with incomplete VRF in maxillary and mandibular teeth both posterior and anterior. Case selection for application of these techniques is critical, because incomplete vertical fractures are difficult to diagnose.

Speaker: Steven D. Bender, DDS|While botulinum toxin is most widely recognized for its cosmetic applications, its therapeutic value in dentistry-and specifically in pain management-is rapidly expanding. This presentation will explore the scientific basis and clinical applications of botulinum toxin for managing pain and dysfunction in the orofacial region. Particular emphasis will be placed on its role in the endodontic practice. Attendees will gain an evidence-based understanding of how botulinum toxin works at the neuromuscular junction, as well as the central nervous system. Current research will be presented to provide a well-balanced overview of the applications for dental practice. Through didactic information and clinical case presentations this session will challenge participants to consider how botulinum toxin may enhance outcomes in complex pain management and interdisciplinary care and provide the endodontic specialist with an additional tool for pain management in clinical practice.

Speaker: Elliot V. Hersh, D.MD, M.S., PhD|This presentation will focus on two areas. 1) Serious adverse drug interactions that may occur in the Endodontic Patient because of drugs that he/she prescribes or administers and 2) Serious adverse drug interactions that may occur in the endodontist himself/herself because of drugs that they are taking for various medical conditions. The three serious drug interactions that may adversely affect the dental patient include; 1) the ability of the antimicrobials metronidazole and fluconazole to inhibit the metabolism of warfarin by blocking cytochrome P-450 2C9 (CYP-2C9), the major metabolic pathway of warfarin, resulting in dramatic increases in patients' international normalized ratios (INRs) and potentially fatal bleeding. 2) The ability of ibuprofen or naproxen sodium to inhibit the renal excretion of the major bipolar disorder drug lithium resulting in tremors, seizures and renal toxicity. 3) The ability of propranolol and other nonselective beta-adrenergic blocking agents to inhibit the vasodilatory effect of epinephrine in dental local anesthetic solutions, leading to severe hypertensive reactions and a concomitant reflex bradycardia. Interactions relevant to the health of dentists themselves include the ability of grapefruit juice/grapefruit to elevate blood levels of statin cholesterol lowering drugs, increasing the risk of myalgia, rhabdomyolysis and acute renal failure. It is important for clinicians to understand the theoretical basis behind these often-predictable interactions, and comprehend the evidenced-based-science that supports their existence.

Learning Objectives:
- Discuss the pharmacological mechanism behind the potentially lethal metronidazole or fluconazole/warfarin interaction.
- Discuss the rationale of why recommending ibuprofen (Advil®) and naproxen sodium (Aleve®) for pain control is a bad idea in a bipolar disorder patient taking lithium (Eskalith®).
- Identify which class of anti-hypertensive drugs where high doses but therapeutic doses of local anesthetic plus epinephrine is most likely to cause a a pressor response with a reflex bradycardia.

Speakers: Mark A. Kerr, D.D.S., Joseph R. Cohen, DDS|Orofacial pain presents a complex diagnostic landscape that often overlaps with endodontic pathology, making accurate diagnosis and effective treatment a significant clinical challenge. The collaboration between orofacial pain specialists and endodontists is emerging as a pivotal strategy in improving patient outcomes, especially in cases where conventional endodontic diagnosis fails to fully explain a patient's symptoms. This interdisciplinary approach enables a more comprehensive evaluation of pain mechanisms, distinguishing odontogenic from non-odontogenic sources, neuropathic conditions, and referred pain patterns. Recent therapeutic advances have enhanced the ability to identify and manage atypical presentations of endodontic pain, such as persistent idiopathic facial pain and neuropathic components of post-root canal treatment.

Speaker: Fred Barnett, D.MD|Root resorption is a common sequelae after traumatic injuries to the periodontal ligament and/or dental pulp. The course of root resorption involves an elaborate interaction among inflammatory cells and mediators, resorbing 'clastic' cells, and hard tissue structures. Types of tooth resorption include internal and external resorption. Internal resorption has been categorized into internal replacement and internal inflammatory resorption. External resorption has been classified into four categories by its clinical and histologic manifestations: external surface, external inflammatory, replacement and ankylosis. This presentation will address the etiology, diagnosis and clinical management of root resorption.
