【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。
[Abstract]:Objective: to analyze the root canal number and morphological characteristics of mandibular central incisor by conical beam CT, and to provide reference for clinical treatment. Methods: the CBCT images of 150 patients in the Ninth people's Hospital affiliated to Shanghai Jiaotong University Medical College were screened. Among them, 79 males and 71 females, 295 mandibular centeral incisors, the number and morphology of root canals were analyzed. Results: 61% of the mandibular central incisors had one root canal. There were 39 central incisors with double root canals, of which 8.8% had two separate apical foramen. Conclusion: the ratio of double root canals in mandibular central incisors is 39.
