Although dental caries has been declining in permanent teeth for many children since the 1960s, previous findings showed caries in primary teeth for preschool children increasing from 24% to 28% between 1988 and 2004. Disparities in caries continue to persist for some race and ethnic groups in the United States. Prevalence of dental sealants--applied to the tooth chewing surfaces to help prevent caries--has also varied among sociodemographic groups. This report describes U.S. youth dental caries and sealant prevalence by race and Hispanic origin for 2011-2012.
自20世纪60年代以来，许多儿童恒牙的龋齿患病率一直在下降，但此前的研究结果显示，1988年至2004年间，学龄前儿童乳牙的龋齿患病率从24%上升至28%。在美国，一些种族和族裔群体的龋齿差异仍然存在。用于牙齿咀嚼面以帮助预防龋齿的牙釉质封闭剂的普及率在社会人口群体中也存在差异。本报告描述了2011年至2012年美国青少年按种族和西班牙裔血统划分的龋齿和牙釉质封闭剂普及率情况。
