The purpose of this study was to describe the prevalence of developmental defects of enamel (DDE) and their relationship with early childhood caries (ECC) among preschool children in Trinidad.
A cross-sectional oral health survey of 251 three- to five-year-old preschool children was undertaken in central Trinidad. The decayed, missing, and filled primary teeth (dmft) index and the DDE index were used to measure visible caries experience and enamel developmental defects, respectively.
Sixty-three children (25.1 percent) had some type of DDE. The most common defects were diffuse opacities and demarcated opacities. A greater severity of visible caries experience was associated with enamel opacities and hypoplasia (P<0.05).
DDEs are prevalent among this group of preschool children in Trinidad and are risk factors for ECC, which emphasizes the importance of preventive oral health care in early childhood for these high-risk children.
本研究旨在描述特立尼达学龄前儿童中釉质发育缺陷（DDE）的患病率及其与幼儿龋齿（ECC）的关系。
在特立尼达中部对251名3至5岁的学龄前儿童进行了横断面口腔健康调查。分别使用乳牙龋失补牙面（dmft）指数和DDE指数来测量可见的龋齿经历和釉质发育缺陷。
63名儿童（25.1%）存在某种类型的DDE。最常见的缺陷是弥漫性混浊和界限性混浊。可见龋齿经历的严重程度增加与釉质混浊和发育不全有关（P<0.05）。
DDE在特立尼达的这群学龄前儿童中很普遍，并且是ECC的危险因素，这强调了对这些高危儿童进行幼儿期预防性口腔保健的重要性。
