中文摘要
目的探讨成都市儿童和青少年颈椎骨龄与牙龄之间的关系，为正畸治疗评价患者骨骼和牙齿发育情况提供依据。方法通过数码曲面断层片和头颅定位侧位片对成都市256例10～16岁儿童和青少年的颈椎骨龄和牙龄进行测量，运用统计学分析方法探讨颈椎骨龄、年龄和牙龄之间的关系。结果通过Spearman相关性分析，颈椎骨龄与年龄之间呈高度相关（r=0.726，P＜0.01），牙龄与年龄之间呈中度相关（r=0.629，P＜0.01），牙龄与颈椎骨龄也呈中度相关（r=0.668，P＜0.01）。结论成都市儿童和青少年颈椎骨龄、年龄和牙龄之间均有相关性，其中颈椎骨龄与年龄呈高度相关性。正畸治疗中判断患者的生长发育情况时，采用颈椎骨龄进行评价优于牙龄。
英文摘要
Objective To investigate the relationship between the stages of calcification of various teeth and cervical vertebral bone ages among children and adolescents in Chengdu. Methods The study subjects consist of 256 children and adolescents in Chengdu with age ranging from 10 to 16 years. All panoramic radiographs and cephalometric radiographs were obtained. The relationship with the stages of chronological ages, calcification of various teeth and cervical vertebral bone ages were analyzed. Results The Spearman rank correlation coefficient revealed highly significant relationships between cervical vertebral bone ages and chronological ages（r=0.726, P＜0.01）. Dental ages and chronological ages had medium relationship（r=0.629, P＜0.01）, also dental ages and cervical vertebral bone ages medium relationship（ r=0.668, P＜0.01）. Conclusion Cervical vertebral bone ages, chronological ages and dental calcification stages have correlation among children and adolescents in Chengdu. The cervical vertebral bone ages have high connection with chronological ages. Cervical vertebral bone age might be a better indicator in judging growth and development of children and adolescents during orthodontic treatment.
