Dental caries status, frequency of sweet consumption and method of toothcleaning of 180 Nigerian elementary schoolchildren aged 8-15 yr were investigated by clinical examination and questionnaire technique. The highest frequency of sweet consumption was recorded for the fee-paying pupils, who also had statistically significantly higher caries prevalence than in non-fee paying schools (P less than 0.001). About 48% and 24% of the fee and non-fee paying pupils respectively had dental caries. There was no significant difference in the sex distribution of the disease (P greater than 0.05). However, there was a significant difference (P less than 0.001) between methods of cleaning the teeth in the two types of schools. The majority (95%) of the fee-paying pupils used only a toothbrush while 51% of the non-fee paying pupils used a chewing stick. Methods for restricting the use of sweet snacks in addition to oral hygiene instruction are discussed as important means to reduce the increasing caries prevalence in schoolchildren in developing countries.
通过临床检查和问卷调查技术，对180名年龄在8至15岁的尼日利亚小学生的龋齿状况、甜食摄入频率和牙齿清洁方法进行了调查。付费学生的甜食摄入频率最高，其龋齿患病率在统计学上也显著高于非付费学校的学生（P<0.001）。约48%的付费学生和24%的非付费学生患有龋齿。该疾病在性别分布上无显著差异（P>0.05）。然而，两类学校在牙齿清洁方法上存在显著差异（P<0.001）。大多数（95%）付费学生仅使用牙刷，而51%的非付费学生使用嚼棒。除了口腔卫生指导外，限制食用甜零食的方法也被讨论为降低发展中国家学童龋齿患病率上升的重要手段。
