In the field of forensic medicine, odontology has got an important role in the determination of age as well as sex. This study is based on modified Gustafson’s method to evaluate the physiological changes occurring in teeth during aging process and to estimate the age using multiple regression analysis. The results of this study show that the correlation coefficients of age with each of six single factors are less than the coefficient of age with the sum of factors, so that best estimation of age is achieved by combination of all six factors. The correlation coefficient between total score and age is 0.9773**. The translucency of root has got highest correlation value. Mean error of age estimation is + 2.33 years. Despite the errors and problems, this method is a cheaper, easier and more practical method and should be used in the first step before more sophisticated methods of age estimation in unknown cadavers. Eventhough the sample size is very small, we derived a new formula for our population. Using this derived formula, we can estimate age of unknown cadavers in our population. Larger sample will give more precise or better results according to the characteristics of our population.
