Abstract

OBJECTIVES

The aim of this retrospective study was to investigate factors associated with increased difficulty in the surgical extraction of impacted lower third molars and to improve identification of difficult cases.

MATERIALS AND METHODS

A total of 680 patients who required 762 surgical extractions of impacted lower third molars from 2009 to 2014 were enrolled in the study. Demographic factors, clinical factors, radiographic factors, surgical extraction difficulty, and presumed causes of difficulty were collected. Data were statistically analyzed using IBM SPSS Statistics version 23.

RESULTS

Age, sex, depth of impaction, and blurred radiographic image influenced difficulty in surgical extraction. The position of the impacted tooth influenced surgical difficulty, especially when it was accompanied by other factors.

CONCLUSION

It is challenging to design a reliable and practical instrument to predict difficulty in surgical extraction of impacted lower third molars. To identify very difficult cases, root investigation using computed tomography is advised when impacted tooth position suggests difficult extraction.

摘要

目的

本回顾性研究旨在调查与下颌阻生第三磨牙手术拔除难度增加相关的因素，并改进对困难病例的识别。

材料与方法

本研究纳入了2009年至2014年期间共680例需要进行762次下颌阻生第三磨牙手术拔除的患者。收集了人口统计学因素、临床因素、影像学因素、手术拔除难度及推测的困难原因。使用IBM SPSS Statistics 23版对数据进行统计学分析。

结果

年龄、性别、阻生深度及影像学图像模糊影响手术拔除难度。阻生牙的位置影响手术难度，尤其是伴有其他因素时。

结论

设计一种可靠且实用的工具来预测下颌阻生第三磨牙手术拔除的难度具有挑战性。为识别极困难病例，当阻生牙位置提示拔除困难时，建议使用计算机断层扫描进行牙根检查。
