title: [Infrared spectroscopy of the enamel in dental fluorosis].
abstract: Structural relationships in orthophosphate (PO4)3-, carbonate (CO3)2-, and hydroxyl (OH)- groups were studied in 2 teeth with grave fluorosis manifestations, removed for orthodontic indications, by infrared spectroscopy. Two intact teeth were examined for control. The findings evidence ar elevated protein level in fluorosis-involved dental enamel and impaired enamel microstructure; this may be explained by specific features of fluorosis clinical manifestation and by increased enamel permeability in grave fluorosis.
