Abstract

Aim:

The aim of thisstudy wasto investigate the relationships between the stages of calcification of teeth (permanent mandibularsecond molar) and cervical vertebrae maturation (CVM).

Materials and Methods:

This study was conducted on 200 Indian children (98 boys and 102 girls), whose panoramic radiographs (orthopantomogram) for mandibular second molar tooth calcification stages and visual appraisals of the lateral cephalograms for CVM stages, were recorded using Demirjian Index (DI) and CVM indicator (CVMI).

Results:

Each stage appeared earlier in female participants than males. A highly significant association was found between DI and CVMI. Stage F and G of DI, which corresponds to Stage 3 of CVMI indicated the start of the peak in mandibular growth, which would be appropriate time to plan for growth modification appliance placement. Stage G of DI also corresponds to Stage 4 of CVMI, i.e., deceleration of adolescent growth spurt. Stage H of DI corresponding to CVMI Stages 5 and 6 indicates that the peak of mandibular growth has already occurred and is not appropriate for functional appliances.

Conclusion:

Mandibular second molar calcification stages are reliable skeletal maturity indicators for the evaluation of growth phases in children.
