[The effect of mineral and organic substances on the desorption of sugar from a soft dental deposit].
Effects of the principle mineral and mineralizing components of the saliva, alimentary organic acids-products of carbohydrate metabolism, and of some other substances of various pH on sugar desorption from soft dental deposit were compared in vitro. The desorbing efficacy was assessed from the concentration of sucrose, derived from a sample of lyophilized dental deposit, in a suspension of the tested reagent. The major mineral components of the saliva, calcium and phosphate, were found to promote extraction of sucrose from the deposit in neutral and weakly alkaline media. Acid medium also favors sucrose desorption. Due to the physiological nature and efficacy of sucrose desorption, solutions of alimentary organic acids may be recommended for prevention of cariogenic situations caused by intake of easily fermented carbohydrates.
