The aim of the present study was to investigate caries prevalence and socioeconomic factors in children with sickle cell anemia. This study was conducted in 160 children with sickle cell anemia aged 3 to 12 years attending the Center for Hematology in Recife, Brazil. Data collection included interviews with guardians concerning social factors and oral examinations to determine the caries prevalence. Statistical analyses were performed using the Kruskal-Wallis and Pearson's chi-square tests at a 5% significance level. The caries prevalence was 55.0%. The dmft index was 2.12, and the DMFT index was 1.50. Income significantly influenced dmft; the mean dmft was 4.57 in children whose family income was less than the Brazilian minimum wage (BMW), whereas in children with a family income three times the BMW or higher, the mean dmft was 2.27. No statistically positive association was found between the educational level of parents and guardians and the caries indices. A statistically significant association was found between dental caries prevalence and family income.
本研究旨在探讨镰状细胞贫血儿童的龋齿患病率和社会经济因素。这项研究在巴西累西腓的血液中心招募了 160 名 3 至 12 岁的镰状细胞贫血儿童进行。数据收集包括对监护人进行有关社会因素的访谈和口腔检查以确定龋齿患病率。采用 Kruskal-Wallis 和 Pearson 卡方检验进行统计分析，显著性水平为 5%。龋齿患病率为 55.0%。dmft 指数为 2.12，DMFT 指数为 1.50。收入显著影响 dmft；家庭收入低于巴西最低工资（BMW）的儿童的平均 dmft 为 4.57，而家庭收入是 BMW 的三倍或更高的儿童的平均 dmft 为 2.27。父母和监护人的教育水平与龋齿指数之间没有统计学上的正相关关系。在龋齿患病率和家庭收入之间发现了统计学上的显著关联。
