[Dental caries, dental fluorosis and use of fluoride tablets. Results of survey by 8, 14, and 20 year old insurance patients].
OBJECTIVE
To assess the prevalence of fluorosis at the age of 8, 14 and 20 years; to evaluate the prevalence of caries and fluorosis at the age of 8 and 14 years in relation tot the use of fluoride tablets during the first 5 years of age.


METHODS
Retrospective study.


METHODS
The investigation was carried out in four cities in the Netherlands.


METHODS
Caries and fluorosis data were obtained in 8-, 14- and 20-year-old persons by clinical examination. For 8- and 14-year-olds results were compared with data about the use of fluoride tablets during the first 5 years of life. These data were obtained by questionnaires completed by the parents when the child was 5 years old.


RESULTS
Prevalence of fluorosis in permanent teeth of 8-, 14 and 20-year-olds was 16%, 31% and 26% respectively. Univariate analysis revealed a statistically significant relation between the frequency of the use of fluoride tablet and caries prevalence in deciduous and permanent teeth on the age of 8. Prevalence of fluorosis and fluoride tablet use did not show such a relation. These findings were confirmed by logistic regression analysis, using frequency of tooth brushing on the age of 5 as possible confounding factor.


CONCLUSIONS
In this group of children the use of fluoride tablets during the first 5 years of life does not seem to increase the prevalence of fluorosis.
