Surgical removal of impacted lower third molars is widely carried out in general dental practice and in many institutional clinics. Despite the fact that there are well established indications for the removal of impacted lower third molars, prophylactic removal of these teeth is still being universally practiced. Some reports have estimated that the proportion of impacted third molars that are removed when no clinically sound justification for surgery is present is between 18% and 50.7%. Justifications for prophylactic surgery include the need to minimize the risk of disease (cysts and tumors) development, reduction of the risk of mandibular angle fracture, increased difficulty of surgery with age, and that third molars have no definite role in the mouth. This article critically examines the literature regarding the relationship between impacted lower wisdom teeth, cysts and tumor development, and mandibular fractures.
在普通牙科诊所和许多机构性诊所中，外科拔除阻生下颌第三磨牙的操作广泛开展。尽管对于拔除阻生下颌第三磨牙已有明确的适应证，但预防性拔除这些牙齿的做法仍普遍存在。一些报告估计，在没有手术的临床合理依据时拔除的阻生第三磨牙比例在18%至50.7%之间。预防性手术的理由包括需要将疾病（囊肿和肿瘤）发生风险降至最低、降低下颌角骨折风险、随着年龄增长手术难度增加以及第三磨牙在口腔中没有明确作用。本文批判性地审视了关于阻生下颌智齿、囊肿和肿瘤发生以及下颌骨折之间关系的文献。
