The effects of trace metal salts on the production of dental caries in rats were investigated. Five day old albino-rats received parenteral injections of a high or low dose of sodium-fluoride (7681494), boric-acid (10043353), iodine (7553562), aluminum-acetate (139128), or vanadium-chloride (7632511). Injections were given daily until the rats were 17 days old. A high sucrose diet was given before mating and was continued for the offspring. Methods of caries evaluation were not reported. Boron exposure reduced susceptibility to molar caries. Fluoride and vanadium were effective caries inhibitors after molar grinding. Before grinding, the combinations of fluoride and boron, and of aluminum and vanadium reduced the incidence of caries. Iodide was not significantly effective. The author concludes that boron is the most effective element of those tested for inhibiting caries production.
