摘　　要：目的探讨拔除下颌第三磨牙导致下唇麻木的相关原因。方法选取2014年1月～2015年12月我院口腔科门诊拔除下颌第三磨牙的患者320例,分析患者年龄、磨牙根尖与下颌神经管距离以及拔牙方法对下唇麻木发生率的影响。结果本研究共有27例患者术后出现下唇麻木,A组与B组下唇麻木发生率相比无差异（P〉0.05）;C组患者下唇麻发生率明显高于A、B组,且均有显著的统计学差异（P〈0.05）;随着拔牙方法创伤程度提高,下唇麻木发生率增加（P〈0.05）。结论下颌第三磨牙根尖与下颌神经管的距离以及拔除方法的创伤程度均是导致下牙槽神经损伤,下唇麻木的重要因素,本研究成果对患者治疗方案的拟定具有重要的临床意义。Objective To explore the factors of removal of mandibular third molars leading to numbness of the lower lip. Methods 320 cases patients extracting mandibular third molars of dentistry in our hospital were selected from january 2014 to december 2015. Age, molars and the mandibular canal affect apical distance and extraction methods leading to numb lower lip were analysised. Results In this study, a total of 27 patients with postoperative numbness of the lower lip, group A has no significant difference(P>0.05) compared with group B, group C lower lip patients were significantly higher than A and B. With the extraction method degree to improve the of trauma, increased incidence of lower lip numbness(P<0.05). Conclusion Mandibular third molar and the mandibular canal from the apical and pull method method degree of trauma were important factors leading to numbness of the lower lip. The findings have important clinical implications for patients to develop a treatment regimen.
