摘要/Abstract

摘要： 选取符合图像资料条件的80例（142颗）患者作为研究对象，探讨基于圆锥光束断层技术（CBCT）评估北京市不同性别人群上颌第二恒磨牙牙根、根管的解剖学异质性及与年龄的关联性。结果显示，相同性别中牙根与根管数目、牙根形态分布、不同性别中牙根形态分布及融合根形态，差异有统计学意义（P<0.05）；女性牙根融合率高于男性（P<0.05）；MB-DB、MB-P、F-R与年龄呈负相关（P<0.05）；不同数目的牙根在牙根、根管数目、形态分布比较，差异有统计学意义（P<0.05）。说明基于CBCT评估的北京市不同性别人群上颌第二恒磨牙牙根、根管的解剖学存在异质性，且其分布与年龄相关。

Abstract: A total of 80 patients (142 teeth) who meet the conditions of the image data were selected as the research objects. The anatomical heterogeneity of the roots and root canals of the maxillary second permanent molars of different genders in Beijing based on cone beam computed tomography (CBCT) and the correlation with age were explored. The results showed that there were statistically significant differences in the number of roots, root canals and the root morphological distribution among the same sex, and in the root morphological distribution and fusion root morphology among different genders (P<0.05). The root fusion rate of females was higher than that of males (P<0.05). MB-DB, MB-P, F-R were negatively correlated with age (P<0.05). There were statistically significant differences in the number of roots, root canals, and morphological distribution of different numbers of tooth roots (P<0.05). It shows that the anatomy of the roots and root canals of the maxillary second permanent molars of different genders in Beijing based on CBCT assessment is heterogeneous, and their distribution is related to age.
