Effect of a Calcium Prerinse on Salivary Fluoride after a 228-ppm Fluoride Rinse was written by Vogel, G. L.;Chow, L. C.;Carey, C. M.;Schumacher, G. E.;Takagi, S..

The objective of this study was to determine if a concentrated calcium prerinse given before a fluoride rinse would cause an increase in the post rinse salivary fluoride (F). A panel of 5 subjects used a 30, 150 or 300 mmol/l calcium lactate prerinse followed by a 1-min NaF rinse. All calcium prerinses significantly increased the 1-h saliva F relative to the NaF control without a prerinse. The maximum increase was produced by the 150 mmol/l calcium lactate prerinse and was about ninefold higher than the NaF control. In the experiment, the researchers used many compounds, for example, Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5Safety of Calcium 2-hydroxypropanoate pentahydrate).
Calcium 2-hydroxypropanoate pentahydrate (cas: 5743-47-5) belongs to alcohols. Under appropriate conditions, inorganic acids also react with alcohols to form esters. To form these esters, a wide variety of specialized reagents and conditions can be used. Secondary alcohols are easily oxidized without breaking carbon-carbon bonds only as far as the ketone stage. No further oxidation is seen except under very stringent conditions.Safety of Calcium 2-hydroxypropanoate pentahydrate
