The aim of this review was to identify the most important variables that determine surgical difficulty of impacted third molar extractions by their consistent showing in previous studies.
Electronic library search for current evidence in the world literature was conducted, and relevant articles were selected, scrutinized, and the findings were compared.
Seven articles were most relevant, and the results of the comparison of the selected articles showed that demographic variable, age; operative variables: surgeon procedure type and number of teeth extracted; and ratiographic variable, depth angulation; and root morphology, are the most consistent determinants of difficulty.
Current evidence is in support of 3 categoreis of variables strongly associated with surgical diffulty of impacted third molars. The most important variables in each of these categories have been identified.
本综述的目的是通过在以往研究中的持续呈现，确定影响阻生第三磨牙拔除手术难度的最重要变量。
对世界文献中的现有证据进行电子图书馆检索，选择相关文章，进行仔细审查，并比较研究结果。
七篇文章最为相关，所选文章的比较结果表明，人口统计学变量年龄；手术变量：外科医生的手术类型和拔牙数量；以及影像学变量深度角度和牙根形态，是最一致的难度决定因素。
目前的证据支持与阻生第三磨牙手术难度密切相关的三类变量。已确定了每类变量中最重要的变量。
