| 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 3个平面的位置关系均是基本稳定的。

| Abstract: | 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. |
