笔者就6～13岁330名学龄儿童口腔进行了调查。结果:全口牙列完好的为14.8%.患龋率为85.15%,受检查龋均为3.05,男女之间无显著差异,年龄越小患病率越高。牙龈炎患病率为50.0%,调查儿童刷牙习惯与龋病,牙龈炎患病率有明显差异。错(牙合)率为8.48%,以深覆(牙合)、前牙拥挤比例最高。本文还调查了舌系带异常占1.21%,其它如:前牙拥挤、乳牙滞留、多生牙等,所占比例很小。资料说明儿童乳牙龋蚀状况和错(牙合)发生的严重程度,应引起重视,提示开展牙病防治,保护乳牙,必须从小做起。
The author investigated the mouth of 330 school-age children aged 6 to 13 years. Results: The complete dentition was 14.8% intact, the prevalence of dental caries was 85.15%, and the number of dental caries was 3.05. There was no significant difference between men and women. The younger the age, the higher the prevalence. The prevalence of gingivitis was 50.0%. Investigation of children’s brushing habits and caries, gingivitis prevalence were significantly different. The rate of malocclusion (occlusion) was 8.48%. In the deep overbite (occlusal occlusion), the ratio of anterior crowbar was the highest. This article also investigated the anomalous tongue laceration accounted for 1.21%, others such as: anterior crowded, deciduous teeth, polygala, etc., a small proportion. Information on the status of dental caries in children with primary deciduous occlusion (occlusal) and the severity of the occurrence should be taken seriously, suggesting that the prevention and treatment of dental diseases, protection of deciduous teeth, we must start small.
