Abstract: Continuous consumption of soft drinks is the main cause of potential oral health problems, including dental caries and erosion. The purpose of this study was to compare the effect of three different types of soft drinks on the release of calcium from the enamel surface of teeth. Forty bovine teeth were selected for the experiment. They were divided into four groups (n=10/group): Group 1 (Coke™), Group 2 (Pepsi™), Group 3 (Sprite™), and Group 4 (distilled water, the control). The pH of each beverage was measured using a pH meter. The release of calcium ions was measured using an atomic absorption spectrophotometer at baseline, 15, 30, and 60 minutes. The results were assessed by analysis of variance and then by the Tukey test (p< 0.05). Coke, with a pH of 2.39, was the most acidic among the soft drinks. Coke, Pepsi, and Sprite showed no significant mean differences in the calcium released, but there was a significant mean difference of these soft drinks with distilled water at 60 minutes. We concluded that prolonged exposure to soft drinks could lead to significant enamel loss.
