Abstract
In newborn rats, NaF in optimal doses promotes bone calcification both by decreasing bone resorption and stimulating calcium deposition. Sodium fluoride also has a preventive action on heparine-induced, cortisone-induced and fracture-induced osteoporosis in 6- to 8-week-old rats, especially if given both before and after experimental fracture and combined after fracture with Na2HPO4 and KH2PO2. Both the above results were observed by the semi-quantitative evaluation of tetracycline labeling vs. microchemical calcium assays.
