Abstract
Aim: To evaluate the skeletal maturity objectively and assess the reliability and validity of this method in North Indian subjects. Materials and Methods: Sixty subjects (8-16 years) were taken and divided into two groups of 30 males and 30 females. For each subject, cervical vertebral bone age (VA) was evaluated by the objective method described by Mito et al. , and bone age (BA) was estimated by Grave and Brown method of hand wrist radiograph. Correlations and average differences between various ages were determined. An analysis of variance and Tukey's post-hoc tests were used to compare various ages at 5% significance level. Results: The correlations between cervical VAs and BAs were higher than other ages and also more in females than males. The analysis of female data showed no statistically significant difference ( P > 0.05) whereas analysis of male data showed statistically significant difference ( P Conclusion: The findings of the present study suggest that this method of objectively evaluating skeletal maturation is reliable and can be applied to North Indian females only. The development of a new method to objectively evaluate cervical VA in males is needed.
