The determination of risk factors for early childhood caries (ECC) is important to the implementation of preventive and restorative measures. However, few studies have addressed the association between ECC and developmental defects of enamel (DDE).
To investigate the association between DDE and ECC, controlling for socioeconomic factors and the presence of dental plaque.
A cross-sectional study was carried out with 387 children aged two to 5 years during the National Immunisation Day held in 2010 in Diamantina, Brazil. Data were collected through clinical examinations and interviews with parents/guardians addressing socioeconomic indicators. Statistical analysis involved the chi-squared test and Poisson regression.
The prevalence of DDE and ECC was 33.9% and 43.3%, respectively. Children with DDE had a greater prevalence rate of ECC (PR: 1.325; 95% CI: 1.093-1.607). Early childhood caries was more prevalent among children with unsatisfactory oral hygiene (PR: 2.933; 95% CI: 2.22-3.86), those who resided in rural areas (PR: 1.267; 95% CI: 1.03-1.55) and those from families with a lower monthly household income (PR: 1.501; 95% CI: 1.06-2.12).
The presence of ECC was associated with the occurrence of DDE in the primary dentition. Place of residence and monthly household income (socioeconomic indicators) and oral hygiene (behavioural factor) exerted an influence on the occurrence of ECC.
确定幼儿龋齿（ECC）的风险因素对于实施预防和修复措施很重要。然而，很少有研究探讨ECC与釉质发育缺陷（DDE）之间的关联。
在控制社会经济因素和牙菌斑存在的情况下，调查DDE与ECC之间的关联。
于2010年在巴西迪亚曼蒂纳举行的全国免疫日期间，对387名2至5岁的儿童进行了一项横断面研究。通过临床检查和与父母/监护人就社会经济指标进行访谈收集数据。统计分析包括卡方检验和泊松回归。
DDE和ECC的患病率分别为33.9%和43.3%。患有DDE的儿童ECC患病率更高（PR：1.325；95%CI：1.093 - 1.607）。幼儿龋齿在口腔卫生不佳的儿童中更为普遍（PR：2.933；95%CI：2.22 - 3.86），居住在农村地区的儿童（PR：1.267；95%CI：1.03 - 1.55）以及家庭月收入较低的儿童（PR：1.501；95%CI：1.06 - 2.12）中更为普遍。
ECC的存在与乳牙列中DDE的发生有关。居住地、家庭月收入（社会经济指标）和口腔卫生（行为因素）对ECC的发生有影响。
