Objectives: 1. Dental age determination from panoramic radiograph using Demirjian method. 2. Skeletal age determination from lateral cephalometric radiograph using Hassel and Farman method. 3. To evaluate the nature of interrelationship between Chronological, Dental and Skeletal age. Methods: The sample for study consisted of 160 radiographs (80 panoramic radiographs and 80 cephalometric radiographs) of 40 boys and 40 girls randomly selected from various schools of Ahmedabad, Gujarat, India in the age group of 6 to 13 years known chronological age. Data was collected and analyzed. Results: A strong correlation exists between Chronological and assessed Dental age in both genders of 7-12age. (r = 0.8) A moderate correlation exists between Chronological and assessed Skeletal age in both genders of 9-13age (r =0.4) A moderate correlation exists between assessed Skeletal and Dental age in both genders of 9-13age (r =0.6) Conclusions: Significant strong correlation was found among Chronological and assessed Dental age. Girls showed an early maturation over boys of the same age group.
