Abstract:

A stock solution of stannous fluoride was aged over a period of 8 weeks and tested at intervals as a base solution for the preparation of 10 stannous fluoride topical solution and, when added to silex, as a component of a prophylaxis paste. The compatibility of this solution was tested with four pumice and with silex in fully prepared prophylaxis pastes. The pumice contained approximately 7.0 stannous fluoride the silex paste, about 3.7. Performance of the test preparations was based upon the amounts of phosphorous withdrawn from enamel surfaces by 0.025 M lactic acid both before and after the test treatment. Protection afforded by the 10 stannous fluoride topical application ranged from 68.3 to 78.8. Silex prophylaxis paste prepared from aging stock solution provided protection of from 68.2 to 79.1. The flour pumice paste, aged as mixed, was 71.6 to 82.8 effective, while a comparable silex paste reduced enamel solubility by 67.9 to 76.9. There was no apparent deleterious effect of age on any of the preparations tested. Author
