龋病是儿童最常见的慢性感染性疾病，主要由变形链球菌和含糖食物对牙釉质的相互作用引起。本研究旨在了解巴赫达尔市小学生龋齿患病率及相关因素。2013年10月至2014年1月，在巴赫达尔市进行了一项以学校为基础的横断面研究。采用系统随机抽样的方法进行儿童抽样调查。使用结构化问卷对儿童和/或父母进行访谈，以收集社会人口统计变量。由经验丰富的牙医使用世界卫生组织制定的龋齿标准获得的临床牙科信息。采用双因素和多因素Logistic回归分析方法对龋病的相关因素进行分析。在147名儿童中，82名(55.4%)是女孩。大多数儿童(67.6%)使用传统方法(一种特殊植物制成的小木棍)清洁牙齿。儿童患龋率为32%(21.8%)。原发龋齿占龋齿总数的75%。缺牙7颗(4.8%)。学龄儿童牙痛和牙菌斑的总比例分别为40(27.2%)和99(67.3%)。1~4级(AOR = 3.9，CI = 1.49~10.4)、清洁习惯差(AOR = 2.6，CI = 1.0 8~6.2)、牙菌斑(AOR = 5.3，CI = 1.6~17.7)和牙痛(AOR = 6.3，CI = 2.4~15.4)与龋病发生显著相关。龋齿是学龄儿童常见的公共卫生问题，与不良的口腔卫生、饮食和看牙习惯有关。因此，预防措施，如口腔卫生、饮食习惯和看牙的重要性等健康教育对儿童是必要的。
Dental caries is the most common chronic infectious disease of childhood caused by the interaction of bacteria, mainly Streptococcus mutans and sugary foods on tooth enamel. This study aimed at determining the prevalence and associated factors of dental caries among primary school children at Bahir Dar city. A school based cross-sectional study was conducted at Bahir Dar city from October 2013 to January 2014. Systematic random sampling technique was used to select the children. Structured questionnaire was used to interview children and/or parents to collect socio demographic variables. Clinical dental information obtained by experienced dentist using dental caries criteria set by World Health Organization. Binary and multiple logistic regression analysis were computed to investigate factors associated with dental caries. Of the 147 children, 82 (55.4%) were girls. Majority of the children (67.6%) cleaned their teeth using traditional method (small stick of wood made of a special type of plant). The proportion of children having dental caries was 32 (21.8%). Primary tooth decay accounted for 24 (75%) of dental caries. The proportion of missed teeth was 7 (4.8%). The overall proportion of toothache and dental plaque among school children were 40 (27.2%) and 99 (67.3%), respectively. Grade level of 1–4 (AOR = 3.9, CI = 1.49 -10.4), poor habit of tooth cleaning (AOR = 2.6, CI = 1.08 - 6.2), dental plaque (AOR = 5.3, CI = 1.6 - 17.7) and toothache (AOR = 6.3, CI = 2.4 – 15.4) were significantly associated with dental caries. Dental caries is a common public health problem in school children associated with poor oral hygiene, dietary and dental visit habits. Therefore, prevention measures such as health education on oral hygiene, dietary habits and importance of dental visit are obligatory for children.
