Introduction: Dental maturity plays an essential role in assessing the chronological age of a person because of its high predictivity. The procedure for assessment of skeletal maturity is composed of visual inspection of the developing bones, their initial formation and consequent changes in shape and size related to ossification. The foot, ankle, hip, elbow, hand-wrist and cervical vertebrae are among the several skeletal portions that have been used to analyze the skeletal maturity. Materials & Methods: This study comprised of 150 male and 150 female subjects ranging in age from 9 to 25 years. A total of 300 dental panoramic radiographs and lateral cephalograms were obtained and analysed. Calcification stages of the mandibular third molar were rated according to the system of Demirijian. Skeletal age and skeletal maturity stages [cervical vertebrae maturity indicators-(CVMI) and middle phalanx of middle finger] were determined by using the method of Hasal and Farman as well as Hagg and Taranger’s method. Results: Correlation between observed age and age predicted on the basis of study parameters among males and females was found in our study. For males, observed age and predicted ages by different methods positively correlated (p<0.001) with each other. The mandibular third molar method was found to have the strongest correlation (r=0.62) followed by the cervical vertebrae (r=0.46) and predicted age by middle phalanx of third finger (r=0.38). In case of females also, observed age and predicted ages by different methods positively correlated (p<0.001) with each other. The mandibular third molar method was found to have the strongest correlation (r=0.50) by middle phalanx of third finger (r=0.48) and predicted age by the cervical vertebrae (r=0.47). Conclusion: The dental and skeletal methods can both be used for age estimation with dental method being more accurate than the skeletal method.
