To quantify longitudinal cranial base growth from prepubertal through postpubertal stages of development, as defined by biological indicators of individual skeletal maturity (cervical vertebral maturation - CVM) method and to determine if there is sexual dimorphism resulting from cranial base growth.
A longitudinal cephalometric study.
The Dental School of Paulista University, Brazil.
36 subjects (21 females, 15 males) who were part of a longitudinal growth study and exhibited normal facial and normal vertical growth patterns.
Growth maturation of cervical vertebrae stages was assessed by two examiners independently. Cranial base measurements were carried out by one individual and repeated after one month. The growth increments over time were assessed with the one-way repeated-measures analysis of variance and post hoc Tukey multiple comparisions.
There were no significant gender differences. There was a significant increase in all cephalometric measures between the different time points. Ba-Na showed the greatest amount of growth (mean change=2.8 mm). From T2-T3, the greatest amount of growth was found for Se-Na (mean change=3.4 mm) and the lowest for CC-Na (mean change=1.4 mm). Comparing overall changes (T1-T3) all the measurements showed statistically significantly increases (P<0.05). For all comparisons of between-stage changes the cranial base grew more than 2.0 mm during the pubertal growth.
Linear variables of cranial base showed significant growth during pubertal stages (pre-peak, peak and post-peak). No significant differences.
根据个体骨骼成熟度的生物学指标（颈椎成熟度 - CVM）方法，量化从青春期前到青春期后的颅底纵向生长，并确定颅底生长是否存在性别差异。
一项纵向头影测量研究。
巴西圣保罗大学牙科学院。
36名受试者（21名女性，15名男性），他们是纵向生长研究的一部分，表现出正常的面部和垂直生长模式。
由两名检查者独立评估颈椎阶段的生长成熟度。颅底测量由一人进行，并在一个月后重复测量。使用单向重复测量方差分析和事后Tukey多重比较评估随时间的生长增量。
没有显著的性别差异。不同时间点之间所有头影测量指标均有显著增加。Ba-Na的生长量最大（平均变化 = 2.8毫米）。从T2到T3，Se-Na的生长量最大（平均变化 = 3.4毫米），CC-Na的生长量最小（平均变化 = 1.4毫米）。比较总体变化（T1 - T3），所有测量结果均显示有统计学显著增加（P < 0.05）。对于所有阶段间变化的比较，颅底在青春期生长期间增长超过2.0毫米。
颅底的线性变量在青春期阶段（峰值前、峰值和峰值后）显示出显著生长。无显著差异。
