Background: The Tooth Coronal Index (TCI) was widely applied in forensic odontology for dental age estimation, based on the inverse relationship between chronological age and the size of the coronal pulp cavity. This study aimed to evaluate the difference between chronological age and dental age estimated using the TCI method in adults. Materials: This study utilized orthopantomograms from 100 patients (50 male and 50 female) who met the inclusion criteria. Methods: This retrospective cross-sectional study analyzed 100 digital panoramic radiographs (50 male and 50 female) that met predefined inclusion criteria. Crown height (CH) and coronal pulp cavity height (CPCH) of mandibular first molars were measured using ImageJ software. TCI values were calculated as (CPCH × 100) / CH. Dental age was estimated using a regression-derived equation. Statistical analyses included normality testing, homogeneity assessment, pair t- test, and R2 analysis. Result: Chronological age data were not normally distributed, whereas dental age data followed a normal distribution. The homogeinity test results indicated that chronological age and dental age did not exhibit a significant variance difference. Pair t-test analysis demonstrated not significant difference between chronological age and dental age. The contribution (R2) of TCI to chronological age was only 0.010, while the remaining variance was explained by other factors. Conclusion: TCI showed minimal predictive value for chronological age, and no significant difference was observed between chronological age and dental age. These findings suggest that TCI alone is insufficient for accurate age estimation and should be complemented with additional indicators in this population.
