title: [Study of dental fluorosis using an ionic microanalyzer].
abstract: Permanent teeth with endemic dental fluorosis, showing mild and moderate mottled enamel, according to the classfication of Dean, were examined with a SMI 300 Cameca ion micro-analyser. In the external third of enamel, abnormally large "sheaths" were disclosed as well as zones characterized by the destruction of prisms. In the dentine, the presence of peritubular dentine rich in Ca, P, FCa, PO, Mg, Na and K has been noted. Hypomineralized spots, poor in these various elements were observed in the intertubular dentine.
