To estimate the prevalence of erosive tooth wear in children aged 12-17 years in the southwest region of San Antonio, Texas, within Bexar County.
A convenience sample of 307 children aged 12-17 years was selected from two junior high schools. The population consisted predominantly of Hispanic Mexican Americans. The true prevalence of erosive tooth wear within the US is known from only one study, and then only for limited sectors of the population. The Tooth Wear Index, Screening for Oral Health using the Association of State and Territorial Dental Directors (ASTDD) criteria and oral health and dietary assessment questionnaires were used as survey parameters. The questionnaire included data on detailed dietary habits relating primarily to the consumption of acidic beverages and foods.
The overall prevalence of erosion within our convenience sample was 5.5 percent. All affected children showed erosive tooth wear low in severity and confined to the enamel with no exposed dentin. A chi-square test was performed to test for associations between the presence of erosion and consumption level of certain acidic foods at a significance level of 5 percent. Few significant and consistent associations were found between erosive tooth wear and consumption frequency categories of groups of acidic foods and beverages using a non-validated food intake questionnaire on purported risk foods. Soda drinks were associated. Mexican acidic foods were not.
This study indicated a low prevalence and low severity of dental erosion in a convenience sample of children aged 12-17 years in southwest San Antonio, Texas. Issues of sampling and response bias preclude these findings being generalized to other populations and regions.The results should be viewed with caution. Because the local consumption of some purported risk foods appears to be increasing, this study provides a base-line for future assessments of erosive tooth wear in this population.
评估德克萨斯州圣安东尼奥市西南部贝克斯县12至17岁儿童中侵蚀性牙齿磨损的患病率。
从两所初中选取了307名12至17岁儿童作为便利样本。人群主要为西班牙裔墨西哥裔美国人。美国侵蚀性牙齿磨损的真实患病率仅在一项研究中可知，且仅针对有限的人群。使用牙齿磨损指数、依据州和地区牙科主任协会（ASTDD）标准进行口腔健康筛查以及口腔健康和饮食评估问卷作为调查参数。问卷包括主要与酸性饮料和食物消费相关的详细饮食习惯数据。
在我们的便利样本中，侵蚀的总体患病率为5.5%。所有受影响的儿童牙齿侵蚀程度低，仅限于牙釉质，无牙本质暴露。进行了卡方检验，以5%的显著性水平测试侵蚀的存在与某些酸性食物消费水平之间的关联。使用一份关于所谓风险食物的未经验证的食物摄入量问卷，在侵蚀性牙齿磨损与酸性食物和饮料组的消费频率类别之间几乎未发现显著且一致的关联。苏打饮料与之相关。墨西哥酸性食物则不然。
本研究表明，在德克萨斯州圣安东尼奥市西南部12至17岁儿童的便利样本中，牙齿侵蚀的患病率和严重程度较低。抽样和应答偏差问题使这些结果无法推广到其他人群和地区。应谨慎看待这些结果。由于当地一些所谓风险食物的消费量似乎在增加，本研究为该人群未来侵蚀性牙齿磨损的评估提供了基线。
