Comparative evaluation of cervical vertebrae maturation index and stages of mandibular second molar calcification: A cross-sectional study

Aim: This study aims to evaluate the relationship between stages of mandibular second molar calcification and cervical vertebrae maturity (CVM) staging for the assessment of pubertal growth spurts in patients.Materials and Methods: Pretreatment panoramic and lateral cephalometric radiographs of 400 patients (200 males and 200 females) were evaluated to ascertain the association of Demirjian index (DI) and CVM method.Results: A highly significant correlation between Cervical vertebrae maturation Index (CVMI) and DI was calculated using Sakoda adjusted Pearson contingency coefficient (r) and a positive correlation was found between CVM and DI in male samples as r = 0.785 and female sample as r = 0.803.Conclusion: A highly significant correlation (r = 0.785 for male subjects and 0.803 for female subjects) was found between DI and CVMI and female subjects showed a higher correlation between skeletal and dental maturity compared to male subjects.
