摘要/Abstract

摘要： 目的:研究上海地区青少年下颌骨的生长时机及生长量。方法:选择上海地区480例(男、女各240例)青少年X线头颅侧位定位片,按性别和颈椎骨成熟度分期法(cervical vertebral maturation method, CVM)分组、测量,应用SPSS15.0软件包计算各测量项目的均数和标准差,采用独立样本t检验比较相邻2组测量结果的差异,并计算下颌骨各生长方向上相邻生长阶段的生长量。结果:男、女下颌综合长(Co-Gn)均在CVMS1-CVMS2及CVMS3-CVMS4期间显著增长(P<0.05),男性CVMS3-CVMS4期间增长量最大(P<0.01),平均增长9.54 mm,女性CVMS1-CVMS2期间增长量最大(P<0.01),平均增长9.09 mm。男性下颌支高度(Co-Go)在CVMS2-CVMS5期均显著增长(P<0.05),以CVMS2-CVMS3期间增长量最大(P<0.01),平均增长8.80 mm,女性则在CVMS1-CVMS4期间显著增长(P<0.05),而最大增长量出现在CVMS1-CVMS2期间(P<0.01), 平均增长6.51 mm。男性下颌体长(Go-Pog)在CVMS3-CVMS4期间生长最显著(P<0.01),平均增长7.55 mm;女性则在CVMS1-CVMS2期间的增长量最大(P<0.01),平均增长5.73 mm。结论:男、女下颌综合长(Co-Gn)、下颌支高度(Co-Go)及下颌体长(Go-Pog)在CVM各期生长量不同,可为临床诊断及治疗方案的选择提供参考。

Abstract: PURPOSE: To study the growth phases and quantities of mandible in Shanghai adolescents. METHODS: The samples included 480 Shanghai adolescents from 8-20 years of age, 240 were male and 240 were female. Both male and female groups were divided into 6 consecutive developmental periods according to cervical vertebral maturation stages. Their cephalometric radiographs were measured and analyzed. Independent-sample t test was conducted by SPSS 15.0 software package. RESULTS: The total mandibular length (Co-Gn) increased significantly from CVMS1 to CVMS2 and CVMS3 to CVMS4 in both male and female group. For male the maximum increase was from CVMS3 to CVMS4 (P<0.01,average 9.54 mm), while female was from CVMS1 to CVMS2(P<0.01,average 9.09 mm). The height of mandibular ramus (Co-Go) increased continuously from CVMS2 to CVMS5 in male group, the significant increase was observed from CVMS2 to CVMS3 (P<0.01, average 8.80 mm). The significant increase in female group was observed from CVMS1 to CVMS2 (P<0.01, average 6.51 mm). In male group, the greatest increase of the mandibular base length (Go-Pog) appeared from CVMS3 to CVMS4 (P<0.01, average 7.55 mm), while in female group, it occurred from CVMS1 to CVMS2 (P<0.01, average 5.73 mm). CONCLUSIONS: The growth amounts of total mandibular length (Co-Gn), mandibular base length (Go-Pog) and ramus length are different at every CVM stages in male and female groups. The present finding will help to make reasonable diagnosis and treatment planning.
