The aim of this study was to assess the prevalence of early childhood caries (ECC) in children and investigate the influence of sociodemographic variables, quality of oral hygiene and child-related aspects. A cross-sectional study was carried out with 593 children aged three to five years. Data were collected through clinical examinations and interviews with parents. Interviews with parents of the children were conducted to acquire information on sociodemographic aspects, breastfeeding, bottle feeding and harmful oral habits. Statistical analysis involved the chi-square test and the Poisson regression. The prevalence of ECC was 53.6%. The occurrence of ECC was greater among children with unsatisfactory oral hygiene (PR: 2.95; 95% CI: 2.42-3.60) and those from a family with a lower monthly household income (PR: 1.62; 95% CI: 1.24-2.10). In conclusion, unsatisfactory oral hygiene and monthly income exerted an influence on the occurrence of ECC among preschoolers.
本研究旨在评估儿童早期龋（ECC）的患病率，并探讨社会人口学变量、口腔卫生质量和儿童相关因素的影响。采用横断面研究方法，对 593 名 3 至 5 岁儿童进行研究。通过临床检查和家长访谈收集数据。对儿童家长进行访谈，以获取社会人口学方面、母乳喂养、奶瓶喂养和不良口腔习惯等方面的信息。统计分析采用卡方检验和泊松回归。ECC 的患病率为 53.6%。口腔卫生状况不佳的儿童（PR：2.95；95%CI：2.42-3.60）和家庭月收入较低的儿童（PR：1.62；95%CI：1.24-2.10）发生 ECC 的风险更高。结论：学龄前儿童口腔卫生状况不佳和月收入对 ECC 的发生有影响。
