调查９２８名２～６岁幼儿园儿童的口腔健康状况。结果：患龋率６４．４７％，受检者龋均３．０７，患者龋均４．８３。其中４～５岁、５～６岁、６～７岁三年龄组之间，患龋率经统计学处理无显著性差异。２～３岁、３～４岁及４～５岁三年龄组间的患龋率，经统计学处理有非常显著性差异（Ｐ＜０．０１）。牙龈炎患病率１７％。错率为３０．１７％，以深覆的比例最高。乳牙发育异常发生率为５．４９％，男女性别之间无显著性差异（Ｐ＞０．０５）。其中，融合牙发生率为２．２６％，以下颌Ｂ＋Ｃ融合最多。此外，还查出数例口腔软组织疾病。资料说明了儿童乳牙龋和牙畸形的严重程度，应引起重视，提示儿童牙病的防治，应尽早进行。
Investigate the oral health status of 928 children aged 2 to 6 years. Results: The caries prevalence was 64.47%. The caries of the subjects was 3.07 and the caries was 4.83. Including 4 to 5 years old, 5 to 6 years old, 6 to 7 years of age between the three groups, caries prevalence was statistically no significant difference. The prevalence of dental caries in 3-year-old, 3-year-old, 4-year-old and 4-to 5-year old groups was statistically significant (P <0.01). The prevalence of gingivitis 17%. The error rate was 30.17%, with the highest percentage of deep overlays. The incidence of abnormal primary teeth development was 5.49%, there was no significant difference between male and female gender (P> 0.05). Among them, the incidence of fusion teeth was 2.26%, with maximal fusion of mandibular B + C. In addition, several cases of oral soft tissue disease were detected. Information shows the severity of deciduous teeth and dental decay in children, should pay attention to prompt dental prevention and treatment of children should be carried out as soon as possible.
