To evaluate the significance of variables such as oral hygiene, dietary habits, socio-economic status and medical history of a child in assessing the level of caries risk and to generate a caries prediction model for pre-school Saudi children.
Cross-sectional study of pre-school children.
Clinics and schools in Riyadh, Saudi Arabia.
A sample of 446 Saudi pre-school children, 199 males and 247 females, with a mean age of 4.13 years, were selected at random from clinics and schools. Selection was limited to subjects who either had no caries (dmft = 0) or who had high caries experience (dmft > 8). Each child was examined for caries experience and oral hygiene status. Their mothers were interviewed through a standardized questionnaire for information about oral hygiene habits of the children, diet history, childhood illness and socio-economic status.
There was a highly significant difference between the two groups in: debris index (P < 0.0001), aged child started tooth brushing, (P < 0.0001), age breastfeeding was stopped (P < 0.005), nocturnal bottle feeding with milk formula (P < 0.001), use of sweetened milk (P < 0.0001), frequency of use of soft drinks (P < 0.0005), frequency of consumption of sweets (P < 0.0001), and age at first dental visit (P < 0.0001). A caries prediction model developed through stepwise multivariate Logistic Regression (LR) analyses showed debris index, use of sweetened milk in bottle, frequency of consumption of soft drinks, frequency of intake of sweets and child's age at the first dental visit to be significant. Predictive probability of the model was 86.31% with a sensitivity of 90.1% and a specificity of 80.6%.
Risk factors for dental caries have been identified and a caries prediction model has been developed for Saudi pre-school children. The prediction model, if verified, may provide with guidance in identifying high caries risk Saudi preschool children as targets for preventive programmes.
评估诸如口腔卫生、饮食习惯、社会经济地位和儿童病史等变量在评估龋齿风险水平中的意义，并为沙特学龄前儿童建立龋齿预测模型。
对学龄前儿童的横断面研究。
沙特阿拉伯利雅得的诊所和学校。
从诊所和学校中随机选取446名沙特学龄前儿童作为样本，其中199名男性，247名女性，平均年龄4.13岁。入选对象仅限于无龋齿（dmft = 0）或有高龋齿经历（dmft > 8）的儿童。对每个儿童进行龋齿经历和口腔卫生状况检查。通过标准化问卷对其母亲进行访谈，以获取有关儿童口腔卫生习惯、饮食史、儿童疾病和社会经济地位的信息。
两组在以下方面存在极显著差异：牙菌斑指数（P < 0.0001）、儿童开始刷牙的年龄（P < 0.0001）、停止母乳喂养的年龄（P < 0.005）、夜间用奶瓶喂配方奶（P < 0.001）、使用加糖牛奶（P < 0.0001）、软饮料使用频率（P < 0.0005）、甜食食用频率（P < 0.0001）以及首次看牙年龄（P < 0.0001）。通过逐步多元逻辑回归（LR）分析建立的龋齿预测模型显示，牙菌斑指数、奶瓶中使用加糖牛奶、软饮料食用频率、甜食摄入频率以及儿童首次看牙年龄具有显著性。该模型的预测概率为86.31%，敏感性为90.1%，特异性为80.6%。
已确定沙特学龄前儿童的龋齿危险因素，并建立了龋齿预测模型。该预测模型若得到验证，可为识别高龋齿风险的沙特学龄前儿童作为预防项目的目标提供指导。
