Abstract

Objectives

We investigated which type of orthopantomography (OPG) was best able to predict neurological alterations of the inferior alveolar nerve (IAN) during extraction of a lower third molar (3 M).

Methods

We analysed cone beam computed tomographies (CBCTs) that were performed at a private dental clinic in Cartagena, Spain over five consecutive years. The CBCTs, together with their corresponding OPGs, had been prescribed for the surgical extraction of a lower 3 M.

Results

We analysed a total of 342 CBCTs and their corresponding OPGs. After explaining the risk of changes in the IAN sensitivity, 37 patients refused to undergo surgical extraction. The incidence of sensitivity alterations in the 332 dental extractions was 62 (19%): 44 were paraesthesias of the IAN, and 18 were associated with darkening of the root and interruption of the cortical line.

Conclusion

When an OPG revealed darkening of the root and interruption of the cortical line, the risk of contact between the lower 3 M and the IAN—that is, the probability of changes in IAN sensitivity—increased by over three-fold.

使用 CBCT 和全景放射摄影预测第三磨牙下牙槽神经敏感性的改变：回顾性横断面研究

目的我们研究了哪种类型的正位像（OPG）最能预测下牙槽神经（IAN）在下第三磨牙（3 M）拔牙过程中的神经改变。方法我们分析了西班牙卡塔赫纳一家私人牙科诊所连续五年进行的锥形束计算机断层扫描（CBCT）。结果我们共分析了 342 个 CBCT 及其相应的 OPG。在解释了 IAN 灵敏度变化的风险后，37 名患者拒绝接受手术拔牙。在 332 例拔牙手术中，灵敏度改变的发生率为 62 例（19%）：结论：当 OPG 显示牙根变黑和皮质线中断时，下 3 M 与 IAN 接触的风险（即 IAN 敏感度发生变化的概率）增加了三倍以上。
