Dental caries and inequalities in dental health are major public health concerns.
To report variation in dental caries experience across deprivation quintiles and the magnitude of inequalities between countries.
Secondary analyses of cross-sectional data from the 2013 Child Dental Health Survey (CDHS) in England, Wales, and Northern Ireland.
Distribution of dental caries across deprivation quintiles were estimated using as proportions and means. The magnitude of inequalities was calculated using the Relative Index of Inequality (RII).
Dental caries experience as indicated by the prevalence (%dmft/DMFT>0) and severity (dmft/DMFT) of 'obvious' and 'clinical' decay experience in both primary and permanent dentitions.
Children from more deprived quintiles showed higher prevalence and severity of dental caries. RIIs for dental caries were greater in England than Wales or Northern Ireland, indicating greater relative inequalities despite lower average dental caries experience. The prevalence and severity of dental caries among the most deprived children in England were 1.7 to 3.7 times greater than those of the least deprived.
There is a deprivation gradient in child dental caries in all three countries, with England showing the greatest inequalities.
龋齿及口腔健康不平等是主要的公共卫生问题。
报告不同贫困五分位数人群的龋齿经历差异以及各国之间不平等的程度。
对2013年英格兰、威尔士和北爱尔兰儿童口腔健康调查（CDHS）的横断面数据进行二次分析。
使用比例和均值估计龋齿在不同贫困五分位数人群中的分布情况。使用不平等相对指数（RII）计算不平等程度。
以乳牙列和恒牙列中“明显”和“临床”龋齿经历的患病率（%dmft/DMFT>0）和严重程度（dmft/DMFT）来表示龋齿经历。
来自贫困程度较高五分位数人群的儿童龋齿患病率和严重程度更高。英格兰的龋齿RII高于威尔士或北爱尔兰，这表明尽管平均龋齿经历较低，但相对不平等程度更大。英格兰最贫困儿童的龋齿患病率和严重程度比最不贫困儿童高1.7至3.7倍。
这三个国家的儿童龋齿情况均存在贫困梯度，其中英格兰的不平等程度最大。
