Trigeminal nerve injuries following dental procedures: A retrospective analysis of malpractice claims from 2016 to 2023 in South Korea

Abstract

BackgroundDental malpractice claims, which pertain to legal actions against dentists accused of clinical negligence that caused harm to patients, have increased in the past ten years in South Korea. The claims are caused by complications, particularly trigeminal nerve injuries, resulting from various dental procedures. Medicolegal issues related to trigeminal nerve injury have not been previously described in South Korea. Therefore, in this study, we aimed to identify the general, dental, and judicial characteristics of closed dental malpractice claims. MethodsThis study was designed as a descriptive study. We collected the data of 51 closed claims related to trigeminal nerve injury resulting from dental procedures such as dental implant emplacement, tooth extraction, and local anesthesia. The claims were decided by courts in South Korea between 2016 and 2023. The general, dental, and judicial characteristics of the claims were analyzed retrospectively. ResultsThe average claim resolution period was 4.2 (range: 1.47–8.39) years post-adverse events that occurred more frequently in dental clinics (68.6 %) than in dental (25.5 %) or general hospitals (5.9 %). Inferior alveolar (66.7 %) and lingual (17.6 %) nerves were injured following dental procedures. The duty to inform was breached in 68.6 % of claims. The dental procedure performed (P < 0.001) and the injured nerve (P < 0.001) were associated with the violation of the duty to care. ConclusionTo improve the quality of dental care services, the analysis of the adverse events using various resources including judgments should be strongly addressed.
