Coronectomy Controversy: The East End's Experience of Coronectomy management and outcomes

Abstract

Introduction: Coronectomies are offered to mitigate damage to the inferior dental nerve where an extraction is deemed high risk. This remains controversial due to the potential for postoperative complications that may present in the maxillofacial or emergency department. Aims and Background: We aim to investigate how our institutions across East London hospitals execute and follow up on coronectomies for mandibular third molars. Material(s) and Method(s): We conducted a retrospective analysis on the outcomes of coronectomies over the last four years across two East London hospitals. Using electronic patient records, we identified over 650 cases and assessed post-operative outcomes, including analgesia and antimicrobial prescriptions and the incidence and nature of complications. Additionally, we reviewed complaints and imaging taken at review appointments. Result(s): Our findings showed complications including pain, infection, and residual enamel structure. Management of such complications varied from local measures and systemic antibiotics to reoperation to remove further tooth structure. Notably, there was no standardized approach among surgeons regarding recall period, post-operative antimicrobials, or analgesia. Conclusion(s): Complications of mandibular third molar coronectomies were infrequent; however, further research is required to establish guidelines for recall periods and post-operative medications. Our findings align with existing literature, emphasizing the need for further follow-up to assess the procedure's long-term efficacy.Copyright © 2025
