Resumo
A quantidade de cálcio, fósforo, magnésio e flúor foi avaliada na mandíbula de ratos com 30 e 60 dias de idade, que receberam, via bucal, doses diárias de 0,25 mg F, contidos em produto comercial tipo comprimido (Fluornatrium), a partir do nascimento. Os resultados obtidos evidenciaram que nos animais tratados o conteúdo de flúor foi maior aos 30 que aos 60 dias, ocorrendo o inverso com relação ao cálcio, não sendo observada nenhuma alteração nos teores de fósforo e magnésio.

Abstract
The dosage of calcium, phosphorus, magnesium and fluoride was analysed in rat mandibles that received 0,25 mg F contained into a commercial product, during 30 and 60 day period, beginning at birth. The results showed that the fluoride content was greater in 30 day old rats. The calcium concentration was greater in the 60 day old rats and no alteration was observed in the phosphorus and magnesium content.
Keywords
