INCREASED DAMAGE TO THE TEETH BY DENTAL CARIES INDUCED BY IONIZING RADIATION (in Russian)
A group of rats (60 days old) given a total x-ray dose of 300 r in fractions of 100 r showed caries in 57.6% of all molars compared to an incidence of caries of 66.6% in a group of rats given a total x-ray dose of 600 r in fractions of 200 r, and an incidence of l.3% in the control group. In another series of experiments the rats were put on a special carbohydrate diet which is used to produce dental caries in experimental animals. The animals were divided into three groups. Group A was fed 0.025 g of calcium glycerophosphate per day. Group B was given water containing 1 mg/l of sodium fluoride. Group C was given no special protection against the onset of dental caries. The three groups of rats were then given a total dose of 300 r in fractions of l00 r. Group C showed dental caries in 75% of all molars, Group B was 65.2% and Group C was 34.3%. The use of calcium glycerophosphate has a protective action on the formation of dental caries. (TTT)
