Abstract

OBJECTIVES

To find the differences between treatment decisions of lower impacted third molars among experts of oral and maxillofacial surgery according to panoramic radiographic and CBCT findings.

METHODS

A retrospective analysis of 62 panoramic radiographs and CBCT of lower third molars evaluated for treatment decisions by 9 independent experts of oral and maxillofacial surgery.

RESULTS

Differences in interpretation of the panoramic radiography were found between surgeons. The absence of radiological signs suspected for risk to the inferior alveolar nerve lead to the decision of extraction according to panoramic radiography without CBCT ( < 0.01). The presence of those signs lead to referral to CBCT by surgeons before treatment but did not change their decision.

CONCLUSIONS

Treatment decision for surgical treatment of the lower third molar can be accepted without CBCT findings. The use of CBCT is popular before extraction of lower third molars. We found that it has a little effect on the treatment decision of the surgical intervention in comparison to panoramic radiography.

摘要

目的

根据全景X线片和锥形束计算机断层扫描(CBCT)结果,找出口腔颌面外科专家在低位阻生第三磨牙治疗决策上的差异。

方法

对62例低位第三磨牙的全景X线片和CBCT进行回顾性分析,由9名独立的口腔颌面外科专家评估治疗决策。

结果

外科医生之间在全景X线片解读上存在差异。根据全景X线片(无CBCT),未发现怀疑对下牙槽神经有风险的放射学征象会导致拔牙决策(<0.01)。这些征象的存在会导致外科医生在治疗前转诊至CBCT,但并未改变他们的决策。

结论

在没有CBCT结果的情况下,低位第三磨牙的手术治疗决策是可以接受的。CBCT在拔除低位第三磨牙前的使用很普遍。我们发现,与全景X线片相比,它对手术干预治疗决策的影响较小。
