To assess the prevalence of dental pain in preschool children through the Brazilian Dental Discomfort Questionnaire (DDQ-B) and its association with dental caries, its severity, and socioeconomic factors. The study included 485 three- to four-year-olds who attended the National Day of Children's Vaccination in São Paulo, Brazil. Parents answered the DDQ-B and questions of socioeconomic conditions. Calibrated dentists assessed dental caries using the decayed, missing, and filled primary teeth (dmft) index and its severity using the pulpal involvement, ulceration of mucosa due to root fragments, fistula, and abscess (PUFA) index. Poisson regression with robust variance was used with a level of significance of five percent. The prevalence of dental pain was 11.8 percent. Dental pain was associated with a prevalence of dental caries (prevalence ratio [PR] equals 2.47; 95 percent confidence interval [95% CI] equals 1.33 to 4.58; P=0.004) and severe caries (PR equals 2.98; 95% CI equals 1.39 to 6.39; P=0.005). Socioeconomic factors were not associated with dental pain. The prevalence of dental pain in preschool children is relevant when assessed through the Brazilian Dental Discomfort Questionnaire. Dental pain is associated with dental caries prevalence and its severity. Socioeconomic factors were not associated with dental pain.
通过巴西牙科不适问卷（DDQ-B）评估学龄前儿童牙齿疼痛的患病率及其与龋齿、龋齿严重程度和社会经济因素的关联。该研究纳入了485名3至4岁在巴西圣保罗参加全国儿童疫苗接种日活动的儿童。家长回答了DDQ-B问卷以及社会经济状况相关问题。经过校准的牙医使用乳牙龋失补牙面（dmft）指数评估龋齿情况，并使用牙髓受累、牙根碎片导致的黏膜溃疡、瘘管和脓肿（PUFA）指数评估龋齿严重程度。采用稳健方差的泊松回归分析，显著性水平为5%。牙齿疼痛的患病率为11.8%。牙齿疼痛与龋齿患病率（患病率比[PR]等于2.47；95%置信区间[95%CI]等于1.33至4.58；P = 0.004）以及重度龋齿（PR等于2.98；95%CI等于1.39至6.39；P = 0.005）相关。社会经济因素与牙齿疼痛无关。通过巴西牙科不适问卷评估时，学龄前儿童牙齿疼痛的患病率值得关注。牙齿疼痛与龋齿患病率及其严重程度相关。社会经济因素与牙齿疼痛无关。
