Abstract

Estimation of an individual's age has received considerable attention in forensic science. Several methods have been described, and abundant results have been obtained and evaluated. Among the numerous methods for dental age prediction in adults, the progressive diminution of the coronal pulp cavity and dental attrition have been primarily used. Although the reliability of age estimation methods using teeth has been demonstrated, correlation between methods has not been reported. Therefore, the aim of this study was to evaluate concurrence between Drusini's methods. We reanalyzed the age of 107 patients (64 male, 43 female) using Drusini's method. The ages had been previously estimated as ranging from 24 to 69 years using Takei's method. Our results revealed a strong correlation between the two methods (r=0.762) and suggest both methods to be suitable for application in Korean individuals younger than 50 years old. A previous study has shown Takei's and Drusini's methods to be reliable for forensic purposes. The strong correlation between the two methods in the present study suggests that it would be reasonable to use the most appropriate method for age estimation dependent on oral state.
