【摘要】：目的:应用锥形束CT(cone-beam computed tomography,CBCT)对维吾尔族上颌中切牙牙根直径及根管管径与年龄的关系进行研究。方法:收集360例维吾尔族患者右上颌中切牙的CBCT影像资料,年龄15~74岁,以10岁为间隔分为6组,测量釉牙骨质界距根尖3/4处的牙根直径及根管管径,对测量结果的性别差异及与年龄的相关性进行分析。结果:牙根直径:男性(6.14±0.348)mm,女性(5.89±0.396)mm;根管管径:男性(1.51±0.344)mm,女性(1.25±0.316)mm;根管管径与牙根直径的比值:男性(0.25±0.059),女性(0.21±0.057),性别间的差异均有统计学意义(P0.05)。根管管径与牙根直径的比值和年龄具有负相关性(R=-0.659,P0.05)。结论:维吾尔族上颌中切牙根管管径与年龄具有相关性,在性别间无明显差异。
[Abstract]:Objective: to study the relationship between root diameter, root canal diameter and age of Uygur maxillary central incisor by conical bundle CT(cone-beam computed. Methods: the CBCT images of right maxillary central incisor were collected from 360 Uygur patients, aged 15 to 74 years, and divided into 6 groups at intervals of 10 years old. The root diameter and the root canal diameter of enamel cementum were measured at 3 / 4 from the apex of the enamel tooth. The sex difference and its correlation with age were analyzed. Results: the root diameter of male was 6.14 卤0.348mm, that of female was 5.89 卤0.396mm, the diameter of root canal was 1.51 卤0.344mm for male and 1.25 卤0.316mm for female, the ratio of root canal diameter to root diameter was 0.25 卤0.059m for male and 0.21 卤0.057m for female. There was a negative correlation between the ratio of root canal diameter and root diameter and age. Conclusion: the root canal diameter of Uygur maxillary central incisor is correlated with age, but there is no significant difference between sex.
