A Study to Compare and Correlate the Status of Maturation in Growing Individuals Using Chronological Age Dental...

To compare and correlate the status of maturation in growing individuals using orthopantomograph (OPG) and lateral cephalogram to establish a reliable relationship between chronological age (CA) and dental maturation (DM) with cervical vertebrae maturation index (CVMI).

Lateral cephalometric radiographs and OPGs of 50 children within the circumpubertal period were collected (male n = 25, age 12-17 years, female n = 25, age 10-15 years) and evaluated for the status of maturation using CA, DM (of mandibular left canine and second molar using Demirjian Index-DI), and CVMI stages.

Chronological age shows a positive correlation with CVMI stages in both groups. Gender-based association and distribution between DI stages of canine and CVMI stages shows that in both male and female sample groups DI G correlates with CVMI stage 1 and 2, DI H correlates with CVMI stage 3. Gender-based association and distribution between DI stages of 2nd molar and CVMI stages show that in the male sample group DI E shows a higher correlation with CVMI stage 1, DI F shows a higher correlation with CVMI stage 1 and 2. DI G shows a higher correlation with CVMI stages 2 and 3. DI H shows a higher correlation with CVMI stage 3. In the female sample group, DI F shows a higher correlation between CVMI stage 1 and 2, DI G and F show a higher correlation with CVMI stage 3.

Mandibular canine, second molar calcification stages, and CA show a positive correlation with CVMI stages in the present study, hence, this can be considered as a reliable indicator in skeletal maturity assessment.
