摘要
Abstract
The accidental displacement of tooth roots into the mandibular canal is a serious complication during tooth extractions in oral and maxillofacial surgery,often resulting in direct damage to the structural and functional integrity of the inferior alveolar neurovascular bundle(IANB).This article reviews the anatomical features of the mandibular canal,the IANB,and adjacent tooth roots;identifies high-risk factors and anatomically vulnerable sites for root displacement;and outlines the clinical manifestations and radiographic characteristics of intraoperative root intrusion into the mandibu-lar canal.Furthermore,management principles,surgical approaches and techniques,inferior alveolar nerve injury treat-ment,and prognostic considerations are discussed.The aim of this review is to provide a comprehensive clinical refer-ence for improving surgical outcomes,and reducing postoperative complications.关键词
