title: The relationship between hip fracture and water fluoridation: an analysis of national data.
abstract: Data from the 1973-1977 National Health Interview Surveys were used to determine whether water fluoridation prevents hip fractures related to osteoporosis. No protective effect was found for fluoride levels of 0.7 ppm, the level recommended for the prevention of dental caries. There are some indications that higher concentrations of fluoride might have a protective effect for groups with a high incidence of osteoporosis. However, no determination of the actual levels needed or the possible adverse effects of high water fluoride levels could be made.
