In order to gain insight into the development of caries prevalence and caries experience among Dutch youth, a meta- analysis was carried out on epidemiological caries data collected in 5 and 6 and 11 and 12 year-olds between 1980 and 2009. From the present analysis it appears that after the mid-1980’s a halt occurred in the decline of caries experience in the primary dentition among 5 and 6 year-olds. At the same time, the percentage of children with a caries-free primary dentition who were covered by public health insurance or participated in institutions for youth dental care decreased. Among 11 to 12 year-olds there is no indication that the prevalence of caries in the permanent dentition has changed. Considering the high percentage of 12 year-olds with a caries-free permanent dentition, an additional improvement in oral health for this age-group will be difficult to achieve. The average restorative index of the primary dentition in 5-6 year-old children covered by public health insurance and children in The Hague appears not to have changed dramatically in the last 15 years.
