The purpose of this study is to assess the stages of skeletal maturity in cone beam computed tomography (CBCT), hand-wrist radiography (HWR) and cephalometric radiography (CR) techniques of orthodontic patients, and associate skeletal maturity stages with chronological age, in a Turkish subpopulation.
Hand-wrist radiographs, cephalometric radiographs and CBCT of 105 patients were evaluated. For evaluation of HWR, the "Hand Bone Age A Digital Atlas of Skeletal Maturity" of Vicente Gilsanz and Osman Ratib (2005) was used. Skeletal maturation in the cephalometric radiographs and sagittal sections of cervical vertebrae obtained by CBCT were evaluated with Hassel and Farman's method (1995). All results were re-evaluated 3 weeks later to assess intra-observer reliability.
Intra-observer reliability coefficients of the skeletal maturity stages in HWR, CR, and CBCT were 0.912, 0.595, 0.756 respectively (p < 0.05). Spearman's correlation coefficient value between skeletal developmental stages in in HWR, CR, and CBCT was found to be 0.785, 0.875, and 0.791, respectively (p < 0.05).
Results of this study reveal that the determination of the skeletal development status with analysis of cervical vertebrae using cephalometric radiographs and CBCT is as reliable method as the evaluation of the hand-wrist radiographs and is compatible with chronological age in a subgroup of the Turkish population. When assessing the skeletal development stages of patients, both CBCT and CR can be used validly, so no extra hand-wrist radiography is required. This information is important for the prevention of increased radiation doses in patients.
本研究旨在评估土耳其人群中正畸患者锥形束计算机断层扫描（CBCT）、手腕部 X 光（HWR）和头颅侧位片（CR）技术的骨骼成熟度分期，并将骨骼成熟度分期与实际年龄相关联。
评估了 105 名患者的手腕部 X 光片、头颅侧位片和 CBCT。对于 HWR 的评估，使用了 Vicente Gilsanz 和 Osman Ratib（2005 年）的“Hand Bone Age A Digital Atlas of Skeletal Maturity”。使用 Hassel 和 Farman 法（1995 年）评估了 CBCT 获得的头颅侧位片和颈椎矢状位片的骨骼成熟度。所有结果在 3 周后重新评估，以评估观察者内可靠性。
HWR、CR 和 CBCT 中骨骼成熟度分期的观察者内可靠性系数分别为 0.912、0.595 和 0.756（p<0.05）。HWR、CR 和 CBCT 中骨骼发育阶段的 Spearman 相关系数值分别为 0.785、0.875 和 0.791（p<0.05）。
本研究结果表明，使用头颅侧位片和 CBCT 分析颈椎来确定骨骼发育状况是一种与评估手腕部 X 光片一样可靠的方法，并且与土耳其人群的实际年龄相匹配。在评估患者的骨骼发育阶段时，CBCT 和 CR 均可有效使用，因此无需额外进行手腕部 X 光检查。这一信息对于预防患者接受过多的辐射剂量非常重要。
