在一项前瞻性研究中，687名患者拔除了1106颗下颌阻生第三磨牙。记录临床、放射学和外科因素。术后，我们检查了常见感觉的形式，以评估感觉缺陷。对患者进行随访，直到完全恢复，或如果感觉未能恢复，至少6个月。术后有3.6%的患侧出现唇觉障碍，2.1%的患侧出现舌觉障碍。这些骚乱中的绝大多数在后续行动期间完全平息。6个月后下牙槽持续性感觉减退发生率为0.91%，舌神经持续性减退发生率为0.37%。然而，在大多数情况下，持续赤字的程度是轻微的。采用卡方检验分析被记录因素与感觉变化的关系。对于下牙槽神经，我们发现患者的年龄、牙根发育、嵌顿程度和神经管的X线位置与感觉障碍以及手术操作的深度和术中下颌管的开口显著相关。就舌神经而言，全身麻醉和个体操作者是神经损伤的主要预测因素。
In a prospective study 1106 impacted mandibular third molars were removed from 687 patients. Clinical, radiographic, and surgical factors were recorded. Postoperatively, we examined the modalities of common sensation in order to assess sensory deficit. The patients were followed up, until complete restitution occurred, or, if the sensibility failed to recover, for at least 6 months. A total of 3.6% of the operated sides demonstrated impairment of labial sensation, and 2.1% of lingual sensation. The vast majority of these disturbances subsided completely during the follow-up period. The incidence of persisting sensory diminution after 6 months was 0.91% for the inferior alveolar, and 0.37% for the lingual nerve. However, the degree of the persisting deficit was slight in most instances. The relationship between the recorded factors and the alteration of sensation was analysed by using the chi (2) test. For the inferior alveolar nerve we found the patient's age, the development of the roots, the degree of impaction, and the radiographic position of the nerve canal to be significantly correlated to sensory deficit, as well as the surgical procedures in the depth of the socket and the intraoperative opening of the mandibular canal. As far as the lingual nerve is concerned, general anaesthesia and the individual operator were the main factors predictive of nerve damage.
