Abstract
Background: The estimation of age through tooth study is one of the main tools to guide the identification of a cadaver. This process becomes more complex in adults because dental structures have already completed their development. Several methods for estimating dental age in adults are based on root transparency, being the developed by Lamendin, et al. (1992) one of the most studied worldwide. There is also one method that was developed for Colombian population: González-Colmenares (2007). Purpose: To identify correlations between real age and dentin translucency, real age, and periodontal recession using the Lamendin and González-Colmenares methods by city and combined cities (Bogotá and Medellín, Colombia). Methods: In this experimental, retrospective, and in vitro study, we performed linear regression models. Coefficients of determination (R2), coefficients of multiple connections, and intersection of the regression line with a 95 % confidence were calculated (p < 0.05). Results: The Student's t test did not show significant differences between the two methods. The correlation between the biological and the estimated age was slightly more accurate with the González-Colmenares (2 %) than the Lamendin’s method. Conclusions: Both methods showed similar accuracy to estimate age in adults.
