摘要/Abstract

摘要： 目的：利用CBCT分析西南地区汉族人双下颌管发生的概率及各型双下颌管的形态学特征，为与之密切相关的口腔临床操作提供参考。方法：选择 2014-2016年期间于自贡市第四人民医院口腔科就诊拍摄CBCT的汉族患者300例，观察患者有无双下颌管，描述其形态学特征并进行统计学分析。结果：西南地区汉族人双下颌管的发生率为19.33%。其中，磨牙后管占比最高（58.75%），其次为根尖管（23.75%）和前行管（15.00%），颊舌向管最少（2.50%）。结论：基于CBCT的研究表明西南地区汉族人双下颌管有较高的发生率，并且各型分支存在形态学差异，临床工作中需重视其影响。

Abstract: Objective To analyze the bifid mandibular canals’ incidence of Chinese Hans residing in southwest, and the morphological features of different types using cone-beam computed tomography (CBCT). Furthermore, to provide the practical reference for relevant clinical operations. Methods 300 Chinese Han patients who attended the Department of Stomatology of Zigong fourth People’s Hospital during 2014 to 2016 were chosen. CBCT was performed to observe the bifid mandibular canal, and its characteristic of morphology were described and analyzed statistically. Results The incidence of southwest Chinese Hans’ bifid mandibular canal was 19.33%. The most frequently encountered type of bifid mandibular canal was retromolar canal (58.75%), followed by apical canal(23.75%) and forward canal (15.00%), the least one was buccal and lingual canal (8%). Conclusion CBCT observation reveals a high prevalence of southwest Chinese Hans’ bifid mandibular canal. Morphological differences exist among different types. The importance of bifid mandibular canal should be emphasized in clinical practice.
