The influence of acid concentration in soft drink on mineral tooth dissolving

Abstract

Demineralization or mineral tooth dissolving can occour if the tooth are under 5.5 pH environtment. Currently, some soft drink under 5.5 pH have been consumpted in general society. The low pH contributes in demineralization because it increases the concentration of hydrogen and this ion will damage hydroxyapatite. The objective of this study was to evaluate the influence of acid concentration in soft drink on mineral tooth dissolving. Design of this study was quasee experiment, included 15 samples of tooth fragment that have been divided into 3 groups. Every sample has been measured for its weight before being immersed in soft drink, and be noted as pre test. Subsequently, Group I, was being immersed in soft drink that contains carbonate acid; Group II, in phosphate acid, and Group III, in the water (control). The measurement of sample weight was done after 24, 48, and 72 hours after immersing, and be noted as post-test. The results of the study shown that the samples that had been immersed in carbonate acid beverages lead to a greater mineral dissolving than phosphate acid and the water.
