The aims of this study were to investigate the dental caries experience among 1-5 year-old children in the two areas of Ulaanbaatar city, and to examine the relationship of dental caries experience with socioeconomic status, eating behaviors, oral hygiene habits, dental plaque accumulation and Mutans Streptococci level.
In 2004/2005, 670 children from the two areas were examined and a questionnaire survey was conducted. Mutans streptococci (MS) levels in the children's and mothers' dental plaque were evaluated using Dentocult SM.
Dental caries prevalence (72%) and mean dmft (4.4) were very high in both areas, however, children in the central area showed higher caries severity than those in the suburban area in 3-5-year-olds (p < 0.05). Higher family income and education level of the mothers were significantly associated with children's higher caries experience. Furthermore, dental caries showed a significant positive relationship with sweets intake and a negative relationship with tooth brushing habits of the children. The children's caries experience was significantly and positively associated with modified debris index (m-DI) scores, and the MS levels in their own and their mothers' dental plaque. Area, sweets intake, prolonged breastfeeding, and high MS level in the dental plaque resulted in significant odds ratios for the development of caries.
The prevalence of dental caries amongst 1-5 year-old children in Ulaanbaatar City, Mongolia was found to be high and was associated with socioeconomic, demographic and behavioural factors.
本研究旨在调查乌兰巴托市两个地区1至5岁儿童的龋齿患病情况，并探讨龋齿患病情况与社会经济地位、饮食行为、口腔卫生习惯、牙菌斑堆积及变形链球菌水平之间的关系。
2004/2005年，对两个地区的670名儿童进行了检查，并开展了问卷调查。使用Dentocult SM评估儿童及其母亲牙菌斑中的变形链球菌（MS）水平。
两个地区的龋齿患病率（72%）和平均龋失补牙数（dmft，4.4）都非常高，然而，在3至5岁儿童中，市中心地区的儿童龋齿严重程度高于郊区儿童（p < 0.05）。母亲较高的家庭收入和教育水平与儿童较高的龋齿患病情况显著相关。此外，龋齿与儿童甜食摄入量呈显著正相关，与刷牙习惯呈负相关。儿童的龋齿患病情况与改良软垢指数（m-DI）得分以及他们自己和母亲牙菌斑中的MS水平呈显著正相关。地区、甜食摄入量、延长母乳喂养时间以及牙菌斑中较高的MS水平导致龋齿发生的显著优势比。
发现蒙古乌兰巴托市1至5岁儿童的龋齿患病率很高，且与社会经济、人口统计学和行为因素有关。
