Correlation between skeletal maturation and dental calcification stages
Introduction: Assessing skeletal maturity and dental development is very common in clinical practice, especially for the purpose of provision of growth modification treatment and age estimation in forensic sciences. Hence the purpose of the present study was to determine the correlation between skeletal maturity and dental calcification stages.
Material & Methods: A total of 103 consecutive patients in age group of 9-16 years were included in the study. Patients with obvious dental pathology or previous history of orthodontic treatment were not included in the study. Lateral cephalometric and panoramic radiographs were taken on the same day. Cervical stages (CS) and Demirjian index (DI) were recorded.
Results: The results showed a positive and strong correlation between skeletal maturity and dental calcification.
Conclusions: Mandibular second molar DI stages are a reliable indicator of skeletal maturity. DI stage E corresponded to cervical stage 2 (pre peak of pubertal growth spurt) and DI stages F and G corresponded to cervical stages 3 and 4 (peak of pubertal growth spurt). DI stage H was associated with cervical stage 6 (end of pubertal growth spurt).
