[Effects of the combination of magnesium fluosilicate and manganese on experimental carries in white rats].

The pattern of experimental caries was examined in rats treated with magnesium fluosilicate associated with manganese and a cariogenic diet. A 33.34% fall in the incidence of caries was observed with respect to a control series, whereas Mg fluosilicate and manganese administered alone caused 30% and 20% reductions respectively. It was also noted that a slight toxic action, expressed as a 3 g fall in body weight, was found with the Mg fluosilicate dose employed; this effect was attenuated by simultaneous administration of manganese.
