摘要：

目的    获取福建省北部地区政和县儿童腭弓高度的测量数据，研究当地儿童腭弓高度生长发育的规律和特点。方法    2003年5月对福建省北部地区建瓯市政和县321名年龄为3 ~ 9岁的儿童，采用电子数显游标卡尺及分规对其上颌模型的乳尖牙间腭弓高度（PHC）、第二乳磨牙间腭弓高度（PHE）及第一恒磨牙间腭弓高度（PH6）进行测量，并对数据进行统计学分析。结果    不同性别间PHC、PHE和PH6差异均无统计学意义（均P > 0.05）。3个年龄组间PHE两两比较，差异均有统计学意义（均P < 0.05）；不同年龄组间PHC及PH6差异均无统计学意义（均P > 0.05）。结论    3 ~ 9岁儿童的第二乳磨牙间腭弓高度随年龄增长而显著增高。

Abstract:

Objective    To obtain the data of the palatal height of the children in Zhenghe，Fujian and to know about the development regularity and characteristics of the growth of the tooth. Methods    The subjects of the study are 321 children between 3 and 9 years old in Zhenghe，Jianou，Fujian in May 2003. We measured the palatal height of dental model using calipers with digital and compasses and analyzed the data using SPSS 11.5. Results          No significant sexual differences of the palatal height were observed in the groups divided by age and position. The palatal height between maxillary deciduous second molars in the group of 5-7 years old was significantly larger than that of the 3-5 years old. Meanwhile，the height in the group of 7-9 years old was significantly larger than that of the 5-7 years old. Conclusions    The palatal height of deciduous second molars in the group of 3-9 years old is significantly larger with age.
