Abstract

Aim: To estimate the age of an individual based on 3D radiographic evaluation of pulp width of maxillary central incisor.

Materials and methods: This study included 185 CBCT images of individuals within age range of 14-64 years. Images were evaluated for maxillary central incisors and pulp width measurements were taken from cementoenamel junction and middle third of root. Obtained data was subjected to correlation and regression analysis from which the age of an individual was predicted. Results of the present study were compared with another study by the same authors.

Results: A negative linear relationship was obtained between age and pulp width. The standard error of estimate (SEE) in sagittal section was 11.36 years and that in coronal section was 11.23 years. The coefficient of determination for sagittal section was 0.107 and for coronal section was 0.127. An obtained regression formula was highly significant. Division of samples into various age groups reduced SEE drastically.

Conclusion: It can be concluded that pulp width of maxillary central incisor is a reliable indicator of age estimation.

利用牙髓对两种不同牙龄估计方法进行比较评估：CBCT 研究。

目的：根据上颌中切牙牙髓宽度的三维影像学评估来估计一个人的年龄：本研究包括 185 张年龄在 14-64 岁之间的 CBCT 图像。对上颌中切牙的图像进行评估，并从牙本质釉质交界处和牙根中间三分之一处测量牙髓宽度。对获得的数据进行相关性和回归分析，并据此预测个人的年龄。本研究结果与同一作者的另一项研究结果进行了比较：结果：年龄与牙髓宽度之间呈负线性关系。矢状切面的估计标准误差（SEE）为 11.36 岁，冠状切面的估计标准误差为 11.23 岁。矢状切面的决定系数为 0.107，冠状切面的决定系数为 0.127。得出的回归公式非常显著。将样本分成不同的年龄组后，SEE 大大降低：可以得出结论，上颌中切牙的牙髓宽度是估计年龄的可靠指标。
