The objective of the study was to assess the prevalence of dental injuries and the influence of determining factors in preschool children from Belo Horizonte, Brazil. A cross-sectional survey was carried out through clinical examinations and the application of a questionnaire to the parents of 419 children aged 0 to 5 years attending preschool. The sample was stratified by region, type of institution and age. The eighteen preschools visited were chosen randomly. The prevalence of traumatic injury to primary teeth was 39.1%. Enamel fractures were the most common traumatic injury (49.7%). Boys were 1.62 times more likely to have dental injuries than girls. Children with inadequate lip coverage were 3.75 times more likely to have a traumatic dental injury than those with adequate lip coverage. Children attending state preschools had nearly two times greater chances of having dental trauma than children attending private preschools. It was concluded that the prevalence of dental injuries in preschool children is high in Belo Horizonte, Brazil and constitutes a public health problem.
该研究的目的是评估巴西贝洛奥里藏特市学龄前儿童牙齿损伤的患病率以及相关决定因素的影响。通过临床检查和向419名0至5岁学龄前儿童的家长发放问卷进行了一项横断面调查。样本按地区、机构类型和年龄进行分层。随机选择了18所访问的幼儿园。乳牙创伤性损伤的患病率为39.1%。牙釉质骨折是最常见的创伤性损伤（49.7%）。男孩发生牙齿损伤的可能性是女孩的1.62倍。唇部覆盖不足的儿童发生牙齿创伤性损伤的可能性是唇部覆盖充足儿童的3.75倍。就读于公立幼儿园的儿童发生牙齿创伤的几率几乎是就读于私立幼儿园儿童的两倍。研究得出结论，在巴西贝洛奥里藏特市，学龄前儿童牙齿损伤的患病率很高，构成了一个公共卫生问题。
