Resumo45Ca turnover and calcium and phosphorus balances were investigated in experimental monkeys maintained on different levels of dietary protein, calcium and vitamin C; chronic fluorosis was induced. Fluoride was found to increase the accretion rate and exchangeable pool size of calcium in animals fed adequate diets. Low-calcium and low-vitamin-C diets were found to increase the accretion rate further. Animals on the low-protein diet, with or without fluoride, showed decreased exchangeable pool size and decreased accretion rate. Fluoride with adequate diet was found to increase the cumulative retention of 45Ca. Low-calcium and low-vitamin-C diets were found to increase further the cumulative retention of labeled calcium. Animals on the low-protein diet, with or without fluoride, had lower retentions. Fluoride on low-calcium diets was found to cause increased retention of dietary calcium and phosphorus.
