目的:使用端骨图(OPG)和头颅侧位图比较和关联生长个体的成熟状态,以建立年龄(CA)和牙齿成熟(DM)与颈椎成熟指数(CVMI)之间的可靠关系。
方法:收集了50名青春期儿童的侧位头颅X光片和OPGs(男性n=25,年龄12-17岁,女性n=25,年龄10-15岁),并使用CA评估成熟状态,DM(使用DemirjianIndex-DI的下颌左犬和第二磨牙),和CVMI阶段。
结果:按时间顺序排列的年龄与两组的CVMI分期呈正相关。犬DI阶段与CVMI阶段之间基于性别的关联和分布表明,在男性和女性样本组中,DIG与CVMI1和2阶段相关,DIH与CVMI3阶段相关。第二磨牙的DI阶段与CVMI阶段之间基于性别的关联和分布表明,在男性样本组中,DIE与CVMI阶段1显示出更高的相关性,DIF与CVMI阶段1和2显示出更高的相关性。DIG显示出与CVMI阶段2和3的较高相关性。DIH显示出与CVMI阶段3的较高相关性。在女性样本组中,DIF示出了CVMI阶段1和2之间的较高相关性,DIG和F示出了与CVMI阶段3的较高相关性。
结论:下颌犬,第二磨牙钙化阶段,在本研究中,CA与CVMI分期呈正相关,因此,这可以被认为是骨骼成熟度评估的可靠指标。

OBJECTIVE: 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).
METHODS: Lateral cephalometric radiographs and OPGs of 50 children within the circumpubertal period were collected (male n = 25, age 12-17 years, female n = 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.
RESULTS: 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.
CONCLUSIONS: 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.
