The influence of chronic exposure to defined emission spectra within the natural UV global range on the skin of the NMRI-mouse was studied. It was shown that after a period of 15 months under suberythemogenic conditions neither carcinomas of skin nor elastic or collagenous tissue alterations were developed.

After 7 years of use of a Na2FPO3 paste, the reduction of DMF surfaces was reduced by 36-38%, relating to the control group. The caries inhibiting effect is statistically ensured. Separate consideration of the first molar shows a caries reduction of 40-42%.

After 7 years unsupervised use of a Na2FPO3 paste the number of new DMF-surfaces was 36 to 38% lower than in the control group. The caries-inhibiting effect is statistically significant (P less than 0.001). Separate consideration of the first molar reduced caries of the other teeth to 40--42%.
