PAIN MANAGEMENT IN ENDODONTICS

     Pain serves as a defense mechanism; however, it is an unpleasant and undesirable sensation. Dental pain is frequently associated with endodontic treatment, and patients with dental anxiety are most concerned about undergoing an endodontic procedure. Therefore, in addition to eliminating pain, addressing the patient's emotional well-being is essential. Endodontists encounter pain-related issues at every stage of treatment—before, during, and after the procedure. Consequently, endodontists must have a comprehensive understanding of pain causes and apply appropriate management strategies. Pain management may require not only clinical interventions but also pharmacological and psychological approaches. Various challenges can arise in clinical pain management. These include difficulty in identifying the source of pain, the sudden onset of acute pain during treatment despite an initially pain-free condition, postoperative pain, and insufficient pain control due to ineffective local anesthesia. This presentation will address key topics related to clinical practice, including identifying the source of pain, treatment options for emergency pain conditions, postoperative pain management, approaches for patients with anxiety, issues with local anesthesia, and the diagnosis, treatment, and prevention of flare-ups. Additionally, pharmacological approaches to pain control will be discussed, offering practical insights for clinical practice.

PERIAPICAL EXTRUSION ACCIDENTS IN ENDODONTICS: CAUSES, PREVENTION, AND CLINICAL MANAGEMENT

     Periapical extrusion accidents in endodontics are the inadvertent displacement of materials beyond the root apex during root canal therapy, which can lead to consequences like as inflammation, infection, cytotoxicity and genotoxicity. It can lead to more serious problems, especially in the case of penetration into the surrounding anatomical structures (eg. the inferior alveolar neurovascular bundles, mental foramen and nerve, and maxillary sinus). These accidents can be caused by factors like excessive instrumentation, overfilling of root canals, improper irrigation, inaccurate working length determination, and inappropriate use of files. When these problems are encountered, the first emergency intervention for focusing to minimize the harm and long-term follow-up of the patient are of great importance. In some cases, advanced surgical interventions may be required. By following correct endodontic protocols, extrusion accidents can be minimized or, if they do occur, successful results can be achieved by performing appropriate interventions.

Dr. Moataz research interests lie in the area of advanced tools and modalities that improve clinical skills of general dentists in the field of endodontics. He has collaborated actively with researchers in several other disciplines of dentistry over the world to achieve such goal. He has served on roughly more than thirty international and national conferences. He also participated as a course director and speaker in many scientific events that was certified from University of Warsaw, Saudi Commission for Health Specialities, Iraq Dental Association, Egyptian Association of Endodontists and Egyptian Dental Syndicate. Dr. Alkhawas is an editorial board member of EC Dental Science Journal. He is an opinion leader for different dental companies that work in the field of endodontics.

    Case selection based on difficulty assessment is a critical step in root canal treatment. Within the endodontic specialty, it is widely acknowledged that the management of complex cases—such as calcified, curved, and MB2 canals should be entrusted to endodontists or general dentists with significant endodontic experience. However, advancements in technology and metallurgy have simplified endodontic procedures without compromising quality. As a result, less experienced clinicians can now manage more complex cases with greater confidence. A prime example of such simplification is single-file asymmetrical reciprocation.

    This lecture will examine the advancements introduced by single-file asymmetrical reciprocation and their influence on case selection based on difficulty assessment. It will also explore how these innovations enable less experienced clinicians, including undergraduate students and newly graduated dentists, to manage more complex cases with greater confidence and efficiency while adhering to the biological and mechanical principles of root canal instrumentation.

     Professor Yared has been extensively involved in teaching. He was Head of the Department of Research and a member of the Department of Endodontics at the Lebanese University, Lebanon. He joined the University of Toronto, Canada in 1999 for a full-time position as Director of the Endodontic Undergraduate Programme. He was granted tenure in 2004. Professor Yared has been elected for 4 consecutive years as the "Best Teacher of the Year", and has received the "Master Bruce Howard Award for Excellence in Teaching" the highest teaching award at the Faculty of Dentistry, University of Toronto.

     Professor Yared has supervised the research projects of graduate endodontic students at the University of Toronto and has published extensively in peer-reviewed international endodontic journals. He has given numerous lectures and continuous education courses worldwide.

     Professor Ghassan Yared has practised endodontics exclusively in Canada for 20 years. He moved to Lebanon where he practises endodontics part-time on a benevolent basis. He is also a visiting professor at the Faculty of Dentistry, Saint Joseph University in Lebanon.

     Professor Yared is the inventor of single file endodontics and asymmetrical mechanical reciprocation, the basis of modern reciprocation. His research is currently focussed on root canal disinfection, pulpal anesthesia and emergency treatment of pulpitis. He introduced a new concept for the management of root canals with a non-instrumentation technique. He also introduced an approach for the emergency management of teeth with symptomatic irreversible pulpitis without a pulpotomy or pulpectomy, and a novel approach for reproducible successful pulpal anesthesia in mandibular molars presenting with asymptomatic irreversible pulpitis without the need of supplementary anesthesia (intra-ligamentary, intra-osseous or intra-pulpal) after the access cavity is started.

THE KEY ROLE OF DIGITAL DENTISTRY IN RESTORING ENDODONTICALLY TREATED TEETH

     Endodontics and restorative dentistry are essential branches of oral healthcare, working together to preserve and restore tooth health and functionality. Digital innovations in dentistry have transformed diagnostic and treatment methods, improving precision, efficiency, and patient outcomes. Therefore, the integration of digital technologies in endodontics and restorative dentistry has significantly changed how dental professionals diagnose, plan, and apply treatments. Incorporating digital advancements in dentistry includes using computer-aided design and computer-aided manufacturing (CAD/CAM) systems, three-dimensional printing(3D), intraoral scanners, digital radiography, and digital treatment records. Digital dentistry therefore enables the use of computer-assisted devices, methods, and technologies—either fully or partially—for the diagnosis, planning, and treatment of dental cases including endodontically treated teeth. CAD/CAM systems offer several benefits, including the ability to produce chairside restorations in a single visit. They provide high precision and quality, eliminate traditional lab methods, and reduce the need for conventional impressions. Additionally, they allow for occlusion adjustments and improve cross-infection control in the dental lab. CAD/CAM systems have also some drawbacks, including high costs, a learning curve, and the potential for devices to become outdated as technology advances. Scanning can also be affected by longer scan lengths, and factors like blood, saliva, and subgingival areas can interfere with the process. Continued education and hands-on training programs can assist dentists in gaining better skills and knowledge. Most dental professions indicate a positive attitude toward digital dentistry and enthusiasm for learning emerging technologies in the dental field. This presentation will summarize the use of CAD/CAM technology in today’s practice and training of dentistry with endodontically treated teeth.
