Materials and Method: A cross sectional study was performed on the panoramic radiographs of 168 individuals with 7-15 years old. Maturation of the seven permanent teeth on the left side of the mandible was determined according to the crown and root development stages; described by Demirjian method. The mean of the dental age (DA) according to the Demirjian was compared to the mean of chronological age (CA). Data were collected and analyzed using SPSS, V18. P-values<0.05 were considered signi-ficance. Results: The mean and the SD of CA was 11.06±2.29 (boys: 11.08±2.31, girls
