Introduction: Cervical vertebrae are used as a reliable tool to assess the skeletal maturation of an individual and predict the maximum growth potential.

Aim and objective: This study aimed to estimate bone age by measuring 3rd and 4th cervical vertebrae

(C3, C4) dimensions on cephalometric radiographs.

Materials and Methods: A total of 100 girls in the age group of 7-15 years were taken into consideration. Using cephalometric radiographs, we measured the cervical vertebral bodies and using a regression formula, cervical vertebral bone age was obtained based on the ratios of measurements in the third and fourth cervical vertebral bodies. It was then correlated with the chronological age.

Results: The Spearman correlation coefficient between chronologic age and cervical vertebrae skeletal maturation was 0.695, with a (p-value < 0.001) which was statistically significant.

Conclusion: The cervical-vertebrae maturation stages are considered clinically useful maturity indicators of the pubertal growth period.
