INTRODUCTION
The aim of this study was to analyze the relationship between the circumpubertal phases of the dentition (early mixed, intermediate mixed, late mixed, early permanent) and skeletal maturity as assessed by means of the cervical vertebral maturation (CVM) method.
METHODS
The sample of 1000 subjects included 250 (125 boys, 125 girls) in each of the 4 dentition phases. Individual skeletal maturity was determined by using the CVM method. The relationship between the skeletal maturity (stages in CVM) and the phases of the dentition was evaluated statistically by means of indicators of diagnostic test performance.
RESULTS
Prepubertal stage 1 (CS1) was the variable diagnosed in the early mixed and intermediate mixed dentitions; pubertal stage 3 (CS3) was the variable diagnosed in the late mixed and early permanent dentitions.
CONCLUSIONS
The early mixed dentition phase showed a strong diagnostic value for the identification of prepubertal skeletal maturity (CS1), whereas the intermediate mixed dentition phase had a low diagnostic value for the same prepubertal stage. Neither the late mixed dentition nor the early permanent dentition appeared to be a valid indicator for the onset of the pubertal growth spurt.
引言
本研究的目的是分析牙列的青春期周围阶段（早期混合牙列、中期混合牙列、晚期混合牙列、早期恒牙列）与通过颈椎成熟度（CVM）方法评估的骨骼成熟度之间的关系。
方法
1000名受试者的样本在4个牙列阶段中各包含250名（125名男孩，125名女孩）。使用CVM方法确定个体骨骼成熟度。通过诊断试验性能指标对骨骼成熟度（CVM阶段）与牙列阶段之间的关系进行统计学评估。
结果
青春期前1期（CS1）是在早期混合牙列和中期混合牙列中诊断出的变量；青春期3期（CS3）是在晚期混合牙列和早期恒牙列中诊断出的变量。
结论
早期混合牙列阶段对识别青春期前骨骼成熟度（CS1）具有很强的诊断价值，而中期混合牙列阶段对同一青春期前阶段的诊断价值较低。晚期混合牙列和早期恒牙列似乎都不是青春期生长突增开始的有效指标。
