Effect of Chewing a Calcium Supplement Before Fluoride Rinse on Salivary Fluoride

NCT04620252

Phase 0 Completed 18 enrolled University of Michigan
RandomizedCrossoverSingle-blindPrevention

Summary

The anticaries effect of fluoride is through the increase in fluoride presence and retention in the oral fluids, reducing dental demineralization and enhancing remineralization. Previous studies showed that a preapplication of calcium (in a rinse) prior to administration of fluoride greatly enhances fluoride concentration in the mouth and the anticaries effect of fluoride. The hypothesis of this study is that the same can be achieved by chewing a calcium supplement prior to a fluoride rinse. The first goal is to determine if chewing these calcium supplements will increase calcium concentration in the oral fluids above baseline levels. Secondly, the calcium supplement with the highest calcium release will be tested before a fluoride rinse to assess the increased retention of fluoride in the oral fluids when compared with the fluoride rinse alone. In both parts, healthy volunteers will participate and saliva will be collected to assess calcium and fluoride concentration.
