This study examined risk factors for children having new cavitated caries between 5 and 9 years old.
Subjects were Iowa Fluoride Study cohort children (mostly Caucasian and of relatively high socioeconomic status) with both primary and mixed dentition caries exams and at least 2 diet diaries recorded between 5 and 8 years old (N=198). Using surface-specific transitions, combined counts of new cavitated caries (d(2-3)f and/or D(2-3)F) were determined from 4 primary second molars, 8 permanent incisors, and 4 permanent molars. Food and beverage intake frequencies were abstracted. Other factors were assessed using periodic questionnaires. Logistic regression identified predictors of new cavitated caries.
Thirty-seven percent had new cavitated caries. The mean new cavitated caries count for all children was 1.17 surfaces (±2.28 SD). In multivariable logistic regression, the following were significantly associated (P<.10) with having new cavitated caries: noncavitated caries experience at 5 years old (odds ratio [OR]=2.67, P=.03); cavitated caries experience at 5 years old (OR=3.39, P=.004); greater processed starch at snack frequency (OR=3.87, P=.07); being older (OR=1.68, P=.04); and less frequent tooth-brushing (P=.001).
Results suggested that increased tooth-brushing frequency and reduced consumption of processed starches as snacks may reduce caries incidence in younger school-aged children.
本研究调查了5至9岁儿童新发龋洞性龋齿的危险因素。
研究对象为参加爱荷华氟化物研究队列的儿童（大多为白种人，社会经济地位相对较高），这些儿童在5至8岁期间接受了乳牙和混合牙列龋齿检查，并记录了至少2份饮食日记（N = 198）。利用特定表面的转变情况，从4颗乳牙第二磨牙、8颗恒牙切牙和4颗恒牙磨牙中确定新发龋洞性龋齿（d(2 - 3)f和/或D(2 - 3)F）的合并计数。提取食物和饮料的摄入频率。通过定期问卷调查评估其他因素。采用逻辑回归分析确定新发龋洞性龋齿的预测因素。
37%的儿童有新发龋洞性龋齿。所有儿童新发龋洞性龋齿的平均计数为1.17个表面（±2.28标准差）。在多变量逻辑回归分析中，以下因素与新发龋洞性龋齿显著相关（P <.10）：5岁时的非龋洞性龋齿经历（优势比[OR] = 2.67，P =.03）；5岁时的龋洞性龋齿经历（OR = 3.39，P =.004）；零食中加工淀粉摄入量增加（OR = 3.87，P =.07）；年龄较大（OR = 1.68，P =.04）；以及刷牙频率较低（P =.001）。
结果表明，增加刷牙频率和减少零食中加工淀粉的摄入量可能会降低小学低年级儿童的龋齿发病率。
