Background: Secondary dentine apposition has been used as a biological indicator in multiple methods for age estimation in human identification. Aim: Determine the correlation between secondary dentine apposition and chronological age in a sample of population from Bogotá aged 21-50 years and develop a multiple linear regression model, which could be used to estimate biological age of adults for forensic identification purposes. Methods: This study was correlational descriptive. The sample consisted of 107 individuals (49 men, 58 women) aged between 20 and 51 years. Periapical radiographs of upper incisors were used for carry out metric analysis of pulpar camera and root conduct. Results: Pearson´s correlation coefficient between age and ratio b/B was -0.59 and for b and c they were -0.56 y -0.43 respectively. The multiple regression analysis showed a mean error of 7.1 years. Conclusions: Correlation betweeen secondary dentine apposition and age was negative. Measurements on root and width were better indicators of age. First formulae was Age=56.07–140.61b/B and R2=0.36. Second model with simple measurements was: Age=38.72–26,35b+5.52B–0.72 LTP and R2=0.38. This method for age estimation in adults does not require histological sections and can be used in living individuals and archeological samples. |
