The aim of this study was to find out if juxta-apical radiolucency (JAR) is a reliable risk factor for injury to the inferior alveolar nerve (IAN) during removal of lower third molars. We designed a cohort study of patients whose dental panoramic tomograms (DPT) had shown JAR before complete removal of lower wisdom teeth. The outcome variable was postoperative permanent neurosensory disturbance of the IAN. A total of 39 patients (50 lower third molars) were identified and screened for permanent neurosensory disturbance. None reported any permanently altered sensation 18 months after the operation. Based on our group, the presence of JAR does not seem to be a reliable predictor of the risk of permanent injury to the IAN during removal of lower third molars.
本研究的目的是查明根尖周透影区（JAR）是否是拔除下颌第三磨牙过程中下牙槽神经（IAN）损伤的可靠危险因素。我们设计了一项队列研究，研究对象为在完全拔除下颌智齿前其牙科全景体层摄影片（DPT）显示有JAR的患者。结果变量是IAN术后永久性神经感觉障碍。共识别出39例患者（50颗下颌第三磨牙），并对其进行永久性神经感觉障碍筛查。术后18个月，无人报告有任何永久性感觉改变。基于我们的研究组，JAR的存在似乎并不是拔除下颌第三磨牙过程中IAN发生永久性损伤风险的可靠预测指标。
