Risk indicators and potential risk factors for caries in 5-year-olds of different ethnic groups in Amsterdam.

The aim of this study was threefold: first, to assess the oral health of Turkish, Moroccan, Surinamese, Dutch and "other" 5-yr-old children living in Amsterdam; second, to identify risk indicators for caries, in addition to ethnicity; and third, to identify potential risk factors related to differences in caries experience in these children. Results showed the mean dmfs scores of Turkish and Moroccan children to be much higher than that of the Dutch and Surinamese children; 8.1 and 8.2 versus 3.6 and 3.4, respectively. The educational level of the parents and the gender of the children were important risk indicators, in addition to ethnicity. The age of the child at which the parents had started to brush their child's teeth, the use of fluoride tablets and the regularity of the brushing behavior in the past could be identified as potential risk factors.
