Age estimation from the physiological changes of teeth

This study was done to evaluate physiological changes in the teeth with the advancing age. 30 cases were taken in this research and the six factors were recorded, these were attrition, periodontal disease, secondary dentine deposition, cementum apposition, root resorption. Each factor was allotted a score of 0–3 depending upon degree of changes in the tooth. Total scores were used to estimate the age using the formula and regression line was obtained. A mean difference ± 2.16 years was found between actual and calculated age
