To determine caries rate trends in children in South Africa and Swaziland since the first published epidemiological study in 1910.
Cochrane Collaboration methods were used to do a systematic review of reported caries rates from 1919 to 2007 in 5-6y, 11-13y and 14-17y children.
There are variations in caries rates among racial groups and between rural and urban areas but secular trends show decreasing prevalence and dmft or DMFT over time.
This systematic review shows decreasing caries rates in children in a developing region of Africa.
自 1910 年首次发表流行病学研究以来，确定南非和斯威士兰儿童的龋齿发病率趋势。
采用 Cochrane 协作组方法，对 1919 年至 2007 年期间 5-6 岁、11-13 岁和 14-17 岁儿童的报告龋齿发病率进行系统评价。
不同种族群体和城乡地区的龋齿发病率存在差异，但随着时间的推移，龋齿发病率呈下降趋势。
本系统评价显示，在非洲一个发展中地区，儿童的龋齿发病率呈下降趋势。
