Abstract
This study aimed to determine the agreement of skeletal maturation (SM) assessed by hand-wrist radiographs and cervical vertebral maturation (CVM) assessed by lateral cephalometric radiographs. It also explored the feasibility of using CVM as an alternative to hand-wrist radiographs among Thai children and adolescents. The samples comprised 95 males and 67 females from Thailand, aged 7–17 years. A total of 162 hand-wrist radiographs and lateral cephalometric radiographs were included. Two experienced oral radiologists independently assessed SM (using Fishman’s method) and CVM (using Baccetti’s method); a third referee observer resolved any discrepancies. The correlation and agreement between the methods were evaluated. The results found a substantial agreement (weighted kappa = 0.594) between SM and CVM. The interobserver discrepancy in categorizing SM stages was mostly found at stage 5, while the most common discrepancy for CVM was at stage 6. A significant positive correlation (Spearman’s correlation coefficient = 0.677, P < 0.001) indicated a moderate to strong association between SM and CVM. The substantial agreement and moderate to strong correlation between CVM and SM highlighted the feasibility of using CVM to assess skeletal growth. However, to ensure reliability, it was necessary to precisely evaluate the appearance of the capping of the epiphyseal plate for SM and the distinction between a rectangular and square cervical spine shape at C3 and C4 for CVM differentiation.
