Abstract

Abstract: Objective: To study the correlation between root and root canal diameter of the maxillary central incisors and age in the Uygur patients by cone-beam computed tomography (CBCT). Methods: CBCT images of 360 maxillary central incisors in Uygur patients were collected and divided into 6 groups at 10 year interval. Root and root canal diameters of maxillary central incisors at the 3/4 level from the cemenal-enamel junction to root apex were measured, and their correlation with gender and age were analyzed. Results: The mean root diameter (mm) in males and females were 6.14±0.348 and 5.89±0.396, respectively, the mean root canal diameter (mm) were 1.51±0.344 and 1.25±0.316, respectively, and the mean ratios between the root canal diameter and the root diameter for male and female were 0.25±0.059 and 0.21±0.057, respectively. There was significantly difference between genders (P＜0.05). There was negative correlation between the ratio of root canal diameter to root diameter and age (R= -0.659,P＜0.05). Conclusion: The root canal diameter of maxillary central incisors is correlated with age in Uygur patients, however, not correlated with age.
