Abstract

Background: In the field of forensic dentistry, various radiographic techniques have been used for age estimation. The coronal pulp cavity index (CPCI) indicates a reduction in the pulp chamber with age as a result of secondary dentin deposition. Methods: The study was conducted on 416 radiovisiographs (RVGs) with the aim to correlate CPCI with chronological age. Digital dental radiographs of four teeth from every subject were taken after written consent. Teeth selected for RVGs in the present study were maxillary canine, maxillary second premolar, mandibular canine, and mandibular first premolar. Two linear measurements were taken for each tooth: one was the tooth crown height (CH) and the second was the coronal pulp height (CPH). Coronal pulp cavity index was calculated for each tooth. Results: Data was statistically analyzed. ANOVA was used to show the strength of the relation between CPCI and chronological age. This study represents the first pilot investigation of this method in a Haryana population. A strong negative linear relationship was found between CPCI and chronological age. Conclusion: Age of an individual can be estimated with a good degree of accuracy using population and sex-specific regression equations. The maxillary second premolar was reported as the most reliable indicator of age in both males as well as females.
