Age Estimation in Human Adults by Root Dentin Transparency

Estimating age from teeth is generally reliable as they are naturally preserved long after all the tissues have disintegrated. Main aim of the study was to estimate the age of an adult individual based on the relation between age and ischolar_main dentin transparency. The study group comprised of 120 single ischolar_mained extracted teeth free from caries, restoration, trauma in the age range of 30-69years of both sexes divided into 4 age groups. Teeth were sectioned labiolingually to 400μ thickness and ischolar_main dentin transparency was measured under stereomicroscope by means of sliding caliper and the results were statistically analyzed. Pearson's correlation coefficient showed high level of correlation of 0.79 between age and ischolar_main dentin transparency. Step wise multiple regression yielded linear regression formulae to predict the chronological age .The full model explained 62% of total variance. Length of ischolar_main dentin transparency is closely correlated with age and can be used to estimate chronological age of an adult individual.
