目的：对１００２名３岁～６岁学龄前儿童的龋齿情况进行统计分析。方法：参照卫生部制定的有关口腔病调查标准，以口镜、探针于自然光线下对儿童牙齿进行检查。结果：龋患率为４５．８１％，龋均为１．３２；３岁组女生高于男生（Ｐ＜０．０５）；６岁组为龋患高峰组；日托高于全托（Ｐ＜０．０５）；龋齿充填率４０．７％。结论：本组儿童患龋人数广而龋均数相对较少，故进一步开展宣传教育及龋齿充填工作，将会有效防止龋齿的发生发展。
Objective: To analyze the dental caries in 1002 preschool children aged 3 to 6 years old. Methods: With reference to the investigation standards for stomatology developed by the Ministry of Health, the children's teeth were examined under natural light by using an oral mirror and a probe. Results: The caries prevalence rate was 45.81%, caries was 1.32; girls in 3-year-old group were higher than boys (P <0.05); 6-year-old caries peak group; .05); dental caries filling rate of 40.7%. Conclusion: This group of children suffer from a large number of caries and caries are relatively small, so further education and dental caries filling work, will effectively prevent the occurrence and development of dental caries.
