摘要
目的:运用锥形束CT分析下颌中切牙的根管数目和形态特征,为临床治疗提供参考。方法:筛选就诊于上海交通大学医学院附属第九人民医院的150例患者的CBCT图像。其中,男79例,女71例,共295颗下颌恒中切牙,对根管的数目以及形态进行分析。结果:61%的下颌中切牙具有1个根管。具有双根管的下颌中切牙占39%,其中8.8%的牙有独立的2个根尖孔。结论:本组下颌中切牙具有双根管的比例为39%,与其他有关不同人种下颌中切牙双根管的研究结果一致。
PURPOSE： To investigate the root canal characteristics of mandibular central incisors using a cone-beam computed tomography （CBCT） technique. METHODS： One hundred and fifty patients （79 males and 71 females） receiving CBCT scan at Shanghai Ninth People＇s Hospital were recruited into this study. A total of 295 image samples of mandibular central incisors were obtained and analyzed in terms of the number and type of root canals. RESULTS： The majority of mandibular central incisors had a single canal （61% possessed a Type I canal system）. Although 39% of the roots possessed two canals, only 8.8% had two separate apical foramina. CONCLUSIONS： The prevalence of two canals of mandibular central incisors in this case series was 39% and is within the range reported by previous studies on case series of different racial origin.
