To assess whether the prevalence of dental caries (DC) was associated with the body mass index (BMI), socioeconomic status (SES), and diet of grade six learners in Pretoria, South Africa (SA).
A cross-sectional study was carried out. Learners underwent an oral and anthropometric examination, while the information on dietary intake and SES were collected using a standardized questionnaire.
Of a possible 529 learners, 440 (83%) participated of whom 53% were boys. The mean age was 11.8 years, and 50% fell into the "medium" SES category. The prevalence of DC was 43%. The mean decayed, missing and filled teeth (DMFT) score was 1.19 (SD = ±1.79), of which the decayed (D) component was the largest 1.07 (SD = ±1.59). Two-thirds (62%) of learners had a normal BMI, and 26% were underweight. Less than half (47%) reported brushing their teeth twice a day; 71% claimed to drink up to one and a half glasses of sugar-sweetened beverages (SSBs), and 67% reported eating one to three sweets a day. The prevalence of DC was not significantly associated with BMI, diet, or SES, although having no caries was associated with eating less than three sweets a day.
The mean DMFT score was relatively low with much of the decayed teeth being untreated. Most learners were classified having a normal BMI, despite having bad eating habits. Oral health in this group of learners may be more influenced by healthcare-seeking behavior and access to healthcare services than by diet alone.
The decayed component was fairly high, which means that there is a huge need for dental treatment, and although prevention and oral health promotion is important, learners with decayed teeth should have access to curative services.

评估南非比勒陀利亚六年级学生的龋齿患病率是否与体重指数（BMI）、社会经济地位（SES）和饮食有关。
开展一项横断面研究。学生们接受了口腔和人体测量检查，同时使用标准化问卷收集饮食摄入和社会经济地位方面的信息。
在可能参与的529名学生中，440名（83%）参与了研究，其中53%为男生。平均年龄为11.8岁，50%属于“中等”社会经济地位类别。龋齿患病率为43%。龋失补牙（DMFT）平均得分是1.19（标准差=±1.79），其中龋损（D）部分最大，为1.07（标准差=±1.59）。三分之二（62%）的学生BMI正常，26%体重过轻。不到一半（47%）的学生报告每天刷牙两次；71%的学生称每天饮用多达一杯半的含糖饮料（SSB），67%的学生报告每天吃一到三颗糖果。龋齿患病率与BMI、饮食或社会经济地位无显著关联，不过无龋齿与每天吃少于三颗糖果有关。
DMFT平均得分相对较低，且大部分龋损牙齿未得到治疗。尽管饮食习惯不良，但大多数学生的BMI分类正常。与单纯饮食相比，这群学生的口腔健康可能更多地受到就医行为和获得医疗服务机会的影响。
龋损部分相当高，这意味着对牙科治疗有巨大需求，虽然预防和口腔健康促进很重要，但有龋损牙齿的学生应能获得治疗服务。如何引用本文：恩坎布勒NR，马迪巴TK，巴亚特A。南非豪登省比勒陀利亚部分小学学生的龋齿、体重指数和饮食。《当代牙科实践杂志》2019；20（11）：1241 - 1248。
