Age Estimation by Using Decayed, Filled and Missing Teeth in Adults: A Practical Method

Age estimation in adults, over the age of 25 years, is a continuous forensic challenge. Before 24 years old, age estimation could be done based on resorbtion of primary teeth, developing permanent teeth and eruption of teeth. Demirgian's and Gustafson's Methods have also encountered problems. The aim of this study was age estimation by clinical examination and panoramic radiography using decayed, filled and missing teeth (DMF Index) in patients between 24-65 years old. This analytic descriptive study composed of 120 patients referred to dental clinic of Iran Petroleum Company. Decayed, filled and missing teeth were evaluated using panoramic radiography. Because of the limitations of radiographs in demonstrating decayed teeth, clinical examination was done too. Finally the relationship between chronological age and dependent variables evaluated using statically tools. Result of this study indicated that there is a direct relation between chronological age and all variables except filled teeth. This relation between age and missing teeth and DMF Index was high. Although, there is an acceptable relationship between chronological age and some variables, these are dependent in different factors like personal hygiene, individual circumstances, social, economical and cultural condition too; So, this method is not suitable for age estimation singly. But, it could be used as an adjunct method for age estimation.
