Comparative evaluation of two different dental age estimation methods using tooth pulp: A CBCT study.
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.
