Prevalence data about tooth erosion has attracted increasing attention in the dental community; however, population-based studies that assessed the impact of demographic, socioeconomic, and dietetic predictors on tooth erosion are scarce. This investigation assessed the prevalence of this condition of a sample of 11-14-year-old schoolchildren and the etiological factors.
A cross-sectional study in a multistage random sample of 944, 11-14-year-old Brazilian schoolchildren was conducted in Santa Maria, Brazil. We recorded the prevalence and severity of tooth erosion, dental caries, and dental enamel hypoplasia. Socioeconomic and habits/dietetic data were collected by a structured questionnaire. Data were analyzed using Poisson regression model taking into account the cluster sample.
Prevalence of tooth erosion was low (7.2%). The most affected teeth were the maxillary incisors. Labial surfaces were more often affected than palatal ones. All the erosive lesions observed were confined to the enamel. Older children [prevalence ratio (PR) = 1.71; 95% confidence interval (CI): 1.06-2.76] with dental enamel hypoplasia (PR = 1.98; 95% CI: 1.21-3.22) were more likely to have tooth erosion. No significant association was observed between tooth erosion, dental caries, habits and dietary patterns, and socioeconomic factors.
The data suggest that tooth erosion was associated with age and presence of hypoplasia. It may indicate the need of strategies to diagnose in early stages and to minimize consequences.
关于牙齿侵蚀的流行数据在牙科领域引起了越来越多的关注；然而，评估人口统计学、社会经济学和饮食预测因素对牙齿侵蚀影响的基于人群的研究却很少。本研究评估了巴西圣玛丽亚市一个 11-14 岁学龄儿童样本的这种情况的患病率以及病因因素。
在巴西圣玛丽亚市进行了一项多阶段随机抽样的横断面研究，共纳入 944 名 11-14 岁的巴西学龄儿童。我们记录了牙齿侵蚀、龋齿和牙釉质发育不全的患病率和严重程度。通过结构化问卷收集社会经济和习惯/饮食数据。采用泊松回归模型分析数据，考虑到聚类样本。
牙齿侵蚀的患病率较低（7.2%）。受影响最严重的牙齿是上颌切牙。唇面比腭面更容易受到影响。所有观察到的侵蚀性病变都局限于牙釉质。年龄较大的儿童（患病率比 [PR] = 1.71；95%置信区间 [CI]：1.06-2.76）和有牙釉质发育不全的儿童（PR = 1.98；95% CI：1.21-3.22）更有可能患有牙齿侵蚀。牙齿侵蚀与龋齿、习惯和饮食模式以及社会经济因素之间无显著相关性。
数据表明，牙齿侵蚀与年龄和发育不全有关。这可能表明需要制定策略来早期诊断并尽量减少后果。
