摘要
目的应用锥形术CT(CBCT)分析泸州地区上颌第三磨牙牙根数目及根管形态。方法收集2016年9月至2017年2月在该院门诊就诊的200例患者的321颗上颌第三磨牙,记录患者年龄、性别,拍摄CBCT影像学资料,分析上颌第三磨牙牙根数目的左右间和性别间差异。结果纳入研究的321颗上颌第三磨牙中,牙根数目以融根牙(56.70%)为主,其次为三根牙(26.48%);根管数目以三根管(38.94%)为主,其次为单根管(30.84%);根据Vertucci根管系统分类,以Ⅰ型根管(65.73%)为主,其次为Ⅴ型根管(10.60%)。上颌第三磨牙牙根数目在左右间差异无统计学意义(P>0.05),但性别间差异有统计学意义(P<0.05)。结论上颌第三磨牙牙根数目多样,根管形态变异性大,根管系统复杂。
Objective To use the cone-beam computed tomography（CBCT） to analyze the root number and root canal morphology of maxillary third molars in Luzhou area. Methods A total of 321 maxillary third molars in 200 outpatients in the stomatological hospital of Southwest Medical University from September 2016 to February 2017 were collected. The age, gender, root number,canal morphology and CBCT imaging data were recorded. The difference in root number of maxillary third molars between left and right sides and between genders were analyzed. Results In included 321 maxillary third molars, the root number was mainly fused root teeth （56. 70%）, followed by three roots teeth（26. 48%）; the number of root canal was mainly three root canals （38.94 %）, followed by single root canal（30. 84 %）. According to the Vertueci root canal classification, 65.73% or root canals were type Ⅰ and 10.60% were type Ⅴ. There was no statistical differences between left and right sides（P〉0.05） ,wherease there was statistically difference between genders（P〈0. 05）. Conclusion The root number of maxillary third molars is variable, the root canal morphology has large variability and the; root Canal system is complex.
