Annual cephalometric radiographs of 67 children were used to analyze mandibular growth during pubescence. Annual increments were calculated for articulare-gonion (Ar-Go), articulare-gnathion (Ar-Gn) and gonion-gnathion (Go-Gn). Pubertal spurts were recorded for annual increments within two years of peak height velocity (PHV) that exceeded the immediately preceding increment by at least 1 mm (corrected for enlargement). Such spurts in mandibular dimensions are common but not universal. They were more common in the boys, but occurred about 1.5 years earlier in the girls. They tended to be larger in boys, although the mean increments in the two sexes were similar before and after the spurts. First pubertal spurts usually occur before PHV, but there was considerable variation in this relationship. Almost all first pubertal spurts occur after ulnar sesamoid ossification and before menarche. The variability of their timing was less in relation to PHV than in relation to skeletal age, menarche or ulnar sesamoid ossification. It can be desirable to determine whether a spurt has occurred in an individual patient. For this purpose, Greulich-Pyle skeletal age may be only slightly more meaningful than chronological age, and neither is sufficiently precise for many clinical applications.
对67名儿童的年度头颅侧位X线片进行分析，以研究青春期下颌骨的生长情况。计算关节点-角点（Ar-Go）、关节点-颏下点（Ar-Gn）和角点-颏下点（Go-Gn）的年度生长增量。记录身高生长高峰速度（PHV）前两年内年度生长增量的青春期突增情况，即增量超过前一年至少1毫米（已校正放大因素）。下颌骨尺寸的这种突增很常见，但并非普遍现象。在男孩中更常见，但女孩比男孩早约1.5年出现。男孩的突增往往更大，不过突增前后两性的平均生长增量相似。首次青春期突增通常发生在PHV之前，但这种关系存在相当大的变异性。几乎所有首次青春期突增都发生在尺侧籽骨骨化之后、月经初潮之前。与PHV相比，其发生时间与骨骼年龄、月经初潮或尺侧籽骨骨化的关系变异性较小。确定个体患者是否发生突增可能是有必要的。为此，格里利希-派尔骨骼年龄可能仅比实际年龄略具意义，且两者对于许多临床应用来说都不够精确。
