Description: Traditional definitions of endodontic care often emphasize localized treatment goals while neglecting broader impacts on systemic health and quality of life. A more comprehensive, patient-centered approach-aligned with the principles of P4 Medicine (predictive, preventive, personalized, and participatory)-may enhance the efficacy, accessibility, and relevance of endodontic therapy.Pulpal disease affects an estimated 30% of the global population, with substantial unmet treatment needs resulting in pain, tooth loss, and diminished daily function. While standardized competencies and technical quality measures guide clinical care, evolving concepts of oral health call for broader success criteria-incorporating patient-reported outcomes and long-term wellness.The integration of P4 principles into endodontic care encourages a proactive shift: predictive diagnostics can help identify individuals at elevated risk; preventive strategies, including minimally invasive care and public health initiatives, may reduce disease incidence; personalization of treatment based on genetics, behavior, and health history enhances clinical precision; and participatory care empowers patients through shared decision-making and education.Yet, significant barriers remain. The high cost of specialist training and inequities in access to care limit the global scalability of these approaches. Expanding educational opportunities, incorporating dental auxiliaries, and leveraging emerging technologies are essential for closing these gaps.This presentation will examine the relationship between endodontic disease and general health, evaluate how evolving treatment goals inform clinical decision-making, and explore practical strategies for implementing P4 concepts in diverse care settings to support lifelong oral health.<br/><br/>
Learning Objectives:
- Discuss the global burden of endodontic disease and its impact on systemic health and quality of life.
- Apply patient-centered and P4-based principles to guide endodontic treatment planning and outcome assessment.
- Identify barriers to delivering optimal care globally and explore models to enhance access, efficiency, and equity.

CE Hours: 1.5
Description: The advent of laser technology has significantly transformed the landscape of medical and dental surgery, offering improved precision, minimal invasiveness, and enhanced healing outcomes. In dentistry, lasers are already well-established in periodontal and oral surgeries. This presentation explores the emerging and increasingly promising role of dental lasers in Endodontic microsurgery, examining their applications in critical procedures such as incision, osteotomy, root-end resection, bone decortication, and photo-biomodulation. Through the presentation of recent data and clinical findings, we evaluate whether lasers can effectively replace traditional instruments in terms of efficacy, precision, and patient outcomes. Key benefits highlighted include minimized postoperative pain, reduced swelling, and faster recovery times. Additionally, for the first time, we introduce the concept and application of laser-guided endodontic surgery, showcasing how this integration enhances surgical navigation and accuracy. The central question-whether lasers will fully replace traditional tools-will be addressed through clinical evidence, technological capabilities, and practical considerations, offering a comprehensive perspective on the future of Endodontic microsurgery.
Learning Objectives:
- Identify the specific clinical procedures in Endodontic microsurgery where lasers can be utilized, including incision, osteotomy, root-end resection, bone decortication, and photo-biomodulation.
- Compare laser-based techniques with traditional surgical instrumentarium, assessing the advantages and limitations of each approach.
- Evaluate the clinical benefits of laser use in microsurgery, such as reduced invasiveness, minimized postoperative pain, decreased swelling, and improved healing outcomes.

Description: This presentation explores the biological relevance of filling lateral canals, grounded in histologic evidence and clinical observations. In the initial phase, the pulp's histological response to bacterial invasion is described. As bacteria colonize the necrotic tissue near the pulp chamber, an inflammatory response develops, while surrounding tissues remain uninflamed. Over time, with or without symptoms, necrosis progresses beyond the root canal orifices, and bacterial biofilms form along canal walls and anatomical complexities. When degeneration involves lateral canals, localized inflammation occurs, typically milder toward the periodontal ligament due to its rich blood supply. Eventually, biofilms may also form in these areas and, in some cases, extend beyond the root canal system, leading to extraradicular infections. The effectiveness of current cleaning protocols and modern devices in removing vital or necrotic tissue from lateral canals is critically evaluated through extensive histological studies on human specimens. It is shown that complete debridement is unachievable, and that forcing obturation materials into lateral canals does not equate to meaningful or effective filling. The discussion is supported by clinical cases and videos, offering a biologically and histologically informed perspective on whether filling lateral canals contributes to healing and long-term success.
Learning Objectives:
- Describe the histological response of the pulp and periapical tissues to bacterial invasion, including the formation of biofilms within lateral canals.
- Evaluate the limitations of current endodontic techniques in cleaning and effectively filling lateral canals, based on histological evidence.
- Assess the clinical significance of lateral canal involvement in endodontic infections and healing outcomes, with a biologically informed perspective.

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.

Description: Root perforations represent one of the most challenging complications during endodontic procedures. These are defined as a communication between the root canal space and the periodontal tissues, and can result as a pathological phenomenon (perforating root resorptions) or a iatrogenic event. To date, factors such as time, size, location, radiolucency adjacent to the perforation, gender or the repair material have been reported as significant prognostic factors. Thus, the primary aim of this this presentation is to perform an exhaustive literature review regarding root perforations outcome. The secondary objective is to describe the clinical management of root perforations and to present the results of a recent investigation carried out in a private practice during 2014-2022 with a minimum follow-up 2 years. A sample size of 82 teeth was retrospectively assessed and the outcome (healed, healing in process, failure) was statistically related to all the possible outcome predictors.
Learning Objectives:
- Describe a well-established protocol to manage root perforations according to the different scenarios (time, size, location of the perforation).
- Review the present literature regarding root perforations treatment outcome.
- Evaluate the success of root perforations repair in combination with the preoperative, intraoperative and postoperative prognostic factors of current investigation.
