摘要
目的 :探讨混合牙列期女性儿童的 5个头影测量平面的角度变化规律。方法 :19名女性儿童 ,10名从 7岁开始 ,另 9名从 9岁开始 ,每年定期拍摄头颅侧位片 1次 ,连续 4年。 7~ 10岁组和 9~ 12岁组分别作纵向研究。两个组有 9~ 10岁的重叠期 ,将结果结合起来进行混合纵向分析 ,从而了解整个 7~ 12岁的头影测量平面的角度变化规律。结果 :在观察期内 ,5个受检平面中 ,FH和BaN平面的角度关系最稳定 ,FH和SN平面的角度关系次之。结论 :在混合牙列期 ,FH、BaN、SN
Objective:The aim of this study was to find the laws of angular changes of 5 cephalometric planes in children with mixed dentitions.Methods: Nineteen female children were annually examined with X_ray, and the cephalometric analysis was performed in continuous 4 years. Of these children, 10 children were investigated from the age of 7 years old, and the other 9 children from 9 years old. The two groups were longitudinally studied. All of the children were observed almost at the same age (9~10 years old) in the two groups, and the results were analyzed with mixed longitudinal methods. All data were analyzed with SPSS 8.0 software.Results: In the observation period, the angular relationship of FH to BaN remain constant among 5 cephalometric planes, and FH to SN was almost in the same situation.Conclusion: In mixed dentition, the angular relationship of FH, BaN and SN barely change.\;
