The aim of this study was to evaluate the prevalence of neurosensory disturbances (NSDs) of the inferior alveolar nerve after dental procedures.
A retrospective study of patient complaints for transient and permanent NSDs was achieved by means of a 10-year follow-up of claims to a national practitioner insurance company. Claims for 3 different dental procedures were analyzed from 157,292 contracts of insurance recorded during this period.
Three hundred eighty-two complaints of NSDs were recorded with 75 permanent injuries (19.6%). The incidence of endodontic treatment and surgical procedures in NSDs cases were 35.3% and 61.5%, respectively, and the prevalence of third molar removals in permanent loss of sensation was 46.6%.
Impacted third molar removal appears to be the main etiology of permanent inferior alveolar nerve sensory deficiency, but endodontic treatments are often implicated and implant placement procedures can cause severe nerve injuries.
本研究旨在评估牙科手术后下牙槽神经神经感觉障碍（NSDs）的患病率。
通过对一家全国性执业医师保险公司10年的索赔随访，对患者关于短暂性和永久性NSDs的投诉进行回顾性研究。分析了在此期间记录的157292份保险合同中3种不同牙科手术的索赔情况。
记录了382例NSDs投诉，其中75例为永久性损伤（19.6%）。在NSDs病例中，牙髓治疗和外科手术的发生率分别为35.3%和61.5%，在永久性感觉丧失中，第三磨牙拔除的患病率为46.6%。
阻生第三磨牙拔除似乎是永久性下牙槽神经感觉缺失的主要病因，但牙髓治疗也常与之相关，种植体植入手术可导致严重的神经损伤。
