Fluorose em ratos induzida pela ingestão contínua de fosfatos brutos de rocha: morfologia do dente e osso alveolar

Abstract

The effects of fluoride toxicity due to Brazilian roch phosphates intake in rats (Ratus ratus) were evaluated by the microscopic examination of tooth and alveolar bone. The rats received a basic diet added Araxá, Patos de Minas and Tapira rock phosphate at two levels of disponíble phosphorus (0.15 and 0.25%). The control rats were fed the sarne basie diet non-supplemented with any phosphate source. Regardless the rock phosphate sources, ali the animals showed dental and bone fluorosis. The contrai rats did not show any lesions.
