Labiomandibular paresthesia after root canal treatment is an accident that is still too frequent despite the development of new endodontic techniques. The aim of this anatomical and clinical study is to advance the understanding of how accidents occur so as to avoid them. This anatomical study made it possible to determine the variability of proximity of the apex of the tooth root to the mandibular bundle, as well as the relationship between the nerve and its satellite artery, and to understand how endodontic filling material spreads into the cancellous bone. The clinical study, which included examination with conventional radiology as well as with imaging techniques, enabled us to identify the exact location of the filling material in relation to the mandibular bundle and to correlate this to the occurrence of clinical symptoms and their diverse manifestations.
尽管新的牙髓治疗技术不断发展，但根管治疗后唇下颌感觉异常仍是一种频繁发生的意外情况。这项解剖学和临床研究的目的是加深对意外情况发生机制的理解，从而避免此类情况。这项解剖学研究能够确定牙根尖与下颌束的接近程度的变异性，以及神经与其伴行动脉之间的关系，并了解牙髓填充材料如何扩散到松质骨中。临床研究包括传统放射学检查以及成像技术检查，使我们能够确定填充材料相对于下颌束的确切位置，并将其与临床症状的发生及其多样表现相关联。
