[Prevalence of dental fluorosis in Chile: a pilot study].

The prevalence of enamel fluorosis and its severity was studied in 118 young men of 2 socio-economic levels. The subjects were born and resided for at least 6 years in Chilean communities with different natural levels of fluoride in drinking water. There was a high prevalence of enamel defect overall (54%) most of it of mild degree (36%). This was not related to the level of fluoride in drinking water, however further studies are needed since Chilean children are receiving fluoride from other sources. A national program to supplement drinking water with fluoride should take this information into account.
