To compare and correlate the status of maturation in growing individuals using orthopantomograph (OPG) and lateral cephalogram to establish a reliable relationship between chronological age (CA) and dental maturation (DM) with cervical vertebrae maturation index (CVMI).
Lateral cephalometric radiographs and OPGs of 50 children within the circumpubertal period were collected (male = 25, age 12-17 years, female = 25, age 10-15 years) and evaluated for the status of maturation using CA, DM (of mandibular left canine and second molar using Demirjian Index-DI), and CVMI stages.
Chronological age shows a positive correlation with CVMI stages in both groups. Gender-based association and distribution between DI stages of canine and CVMI stages shows that in both male and female sample groups DI G correlates with CVMI stage 1 and 2, DI H correlates with CVMI stage 3. Gender-based association and distribution between DI stages of 2nd molar and CVMI stages show that in the male sample group DI E shows a higher correlation with CVMI stage 1, DI F shows a higher correlation with CVMI stage 1 and 2. DI G shows a higher correlation with CVMI stages 2 and 3. DI H shows a higher correlation with CVMI stage 3. In the female sample group, DI F shows a higher correlation between CVMI stage 1 and 2, DI G and F show a higher correlation with CVMI stage 3.
Mandibular canine, second molar calcification stages, and CA show a positive correlation with CVMI stages in the present study, hence, this can be considered as a reliable indicator in skeletal maturity assessment.

使用曲面体层摄影（OPG）和头颅侧位片比较并关联生长中个体的成熟状态，以建立实足年龄（CA）、牙齿成熟度（DM）与颈椎成熟指数（CVMI）之间可靠的关系。
收集50名青春期前后儿童的头颅侧位X线片和OPG（男性25名，年龄12 - 17岁；女性25名，年龄10 - 15岁），并使用CA、DM（采用Demirjian指数 - DI评估下颌左侧尖牙和第二磨牙）和CVMI分期评估成熟状态。
两组中，实足年龄与CVMI分期均呈正相关。基于性别的尖牙DI分期与CVMI分期之间的关联和分布表明，在男性和女性样本组中，DI G与CVMI 1期和2期相关，DI H与CVMI 3期相关。基于性别的第二磨牙DI分期与CVMI分期之间的关联和分布表明，在男性样本组中，DI E与CVMI 1期相关性更高，DI F与CVMI 1期和2期相关性更高。DI G与CVMI 2期和3期相关性更高。DI H与CVMI 3期相关性更高。在女性样本组中，DI F与CVMI 1期和2期相关性更高，DI G和F与CVMI 3期相关性更高。
在本研究中，下颌尖牙、第二磨牙钙化阶段和CA与CVMI分期呈正相关，因此，这可被视为骨骼成熟度评估中的可靠指标。
