Abstract

Objective: To investigate (1) the relationships between the stages of mandibular second molar calcification and skeletal maturity; and (2) whether second molar calcification stages can be used as a reliable diagnostic tool to determine skeletal maturity.

Materials and methods: Samples were derived from panoramic radiographs and lateral cephalograms of 300 subjects (137 males and 163 females) with ages ranging from 9 to 18 years, and estimates of dental maturity (Demirjian Index [DI]) and skeletal maturity (cervical vertebrae maturation indicators [CVMI]) were made.

Results: A highly significant association (C* = 0.854 for males and 0.866 for females) was found between DI and CVMI. DI stage E corresponded to stage 2 of CVMI (pre-peak of pubertal growth spurt) and DI stages F and G corresponded to stages 3 and 4 of CVMI (peak of pubertal growth spurt). DI stage H was associated with stages 5 and 6 of CVMI (end of pubertal growth spurt).

Conclusion: A highly significant association exists between DI and CVMI. Mandibular second molar DI stages are reliable indicators of skeletal maturity.
