[The caries inhibiting action of fluoride gels in animal experiments]

In a short-term animal test, 70 rats were classified into five groups, two fluoride gel groups with and without phosphate addition, one Elmex Gelée group and one placebo gel group. Another group served as a control group. The results found in the active substance groups were statistically significant, as compared to the placebo and control groups. The question as to why the phosphate addition used inhibited caries more successfully, could not be answered.
