Abstract

Objective

Various methods have been employed to determine skeletal maturity, based on height, weight, frontal sinus development, dental calcification sexual maturation and biomarkers. This study aimed to evaluate the validity and reliability of the Quantitative Cervical Vertebral Maturation Index (QCVMI) in assessing skeletal maturity and compare it with established radiographic maturity indicators, including Fishman's Skeletal Maturity Index, Hassal and Farman's CVMI, Modified MP3 Method, Baccetti's CVMI and correlation between QCVMI and mandibular growth increments.

Material and methods

A cross-sectional study was conducted on 120 patients. Lateral cephalograms and hand-wrist radiographs were analysed using Digimizer software. Agreement analysis was performed using Bland-Altman plots, while inter- and intra-rater reliability was assessed using Intraclass Correlation Coefficients (ICC). Lin's Concordance Correlation Coefficient (CCC) and the Bradley-Blackwood test were used for comparative assessment. ROC curve analysis determined diagnostic accuracy, and Pearson correlation coefficients and regression analysis assessed the relationship between QCVMI and mandibular growth increments.

Results

QCVMI demonstrated excellent agreement with Fishman's SMI, very good agreement with the Modified MP3, and good agreement with Hassal and Farman's CVMI and Baccetti's CVMI. High intra- and inter-rater reliability confirmed its reproducibility. ROC analysis showed QCVMI had the highest diagnostic accuracy compared to Fishman's SMI. A strong correlation was observed between QCVMI and mandibular growth increments, indicating its predictive efficacy for growth spurts.

Conclusion

QCVMI is a valid and reliable skeletal maturity assessment tool, demonstrating strong agreement with established indicators while enhancing objectivity and reproducibility. It effectively predicts mandibular growth spurts, making it valuable for orthodontic treatment planning.

定量颈椎成熟指数（QCVMI）的效度和信度评价：一项横断面研究

目的基于身高、体重、额窦发育、牙钙化、性成熟和生物标志物，已经采用了各种方法来确定骨骼成熟度。本研究旨在评价定量颈椎成熟度指数（Quantitative Cervical椎体成熟度指数，QCVMI）评估骨骼成熟度的有效性和可靠性，并将其与现有的影像学成熟度指标进行比较，包括Fishman的骨骼成熟度指数、Hassal和Farman的CVMI、改良MP3法、Baccetti的CVMI以及QCVMI与下颌生长增量的相关性。材料与方法对120例患者进行横断面研究。采用Digimizer软件对侧位头片和腕片进行分析。使用Bland-Altman图进行一致性分析，使用类内相关系数（ICC）评估组间和组内信度。采用Lin’s Concordance Correlation Coefficient （CCC）和Bradley-Blackwood检验进行比较评价。ROC曲线分析确定诊断准确性，Pearson相关系数和回归分析评估QCVMI与下颌生长增量的关系。结果qcvmi与Fishman的SMI具有很好的一致性，与改良MP3具有很好的一致性，与Hassal和Farman的CVMI和Baccetti的CVMI具有很好的一致性。较高的组内和组间信度证实了其重复性。ROC分析显示，与Fishman的SMI相比，QCVMI具有最高的诊断准确性。QCVMI与下颌生长增量之间存在很强的相关性，表明其对生长突增的预测作用。结论qcvmi是一种有效、可靠的骨骼成熟度评估工具，与已建立的指标具有较强的一致性，同时具有较高的客观性和可重复性。它有效地预测下颌生长突增，使其对正畸治疗计划有价值。
