The aim of this study is to correlate dental age by radiographic evaluation using Demirjian method with the chronological age in human population of the ages ranging from 6 years to 16 years.
To compare the dental age and chronological age by using Panoramic Radiographs of subjects from Ambala using Demirjian method. (b) To evaluate the efficacy of Demirjian method of dental age estimation to establish it as an efficient method to predict chronological age.
300 subjects consisting of 150 males and 150 females with the age ranging between 6 to 16 years were taken. The subjects were selected and their panoramic radiographs depicting the dental age were used to determine the chronological age by the use of Demirjian's method.
Chronological age and dental age showed high degree of linear correlation between 6–15 years of combined male and female population. When chronological age was compared with dental age using Demirjian method, total male sample and female sample showed statistically significant linear Pearson correlation of p <0.001. The chronological and dental age showed significant positive correlation between male and female sample i.e. (P<0.01).
The dental age is consistently and significantly correlated to chronological age in the population from Ambala in North India.
