Abstract

There are many concerns about the erosive effects of acidic beverages. In this study, the effects of Pepsi-Cola (pH 2.41) on bovine enamel and the rehardening effect resulting from intraoral exposure of the teeth were determined by microhardness testing (Vicker's Hardness Number). Bovine enamel specimens (VHN 380.00 ± 12.74) were immersed in 100 ml of Pepsi-Cola for five minutes and subsequently exposed to human intraoral environment through the use of a removable resin plate. Microhardness testing was performed on specimens after one hour, twenty-four hours and forty-eight hours of exposure to an intraoral environment. The microhardness value was significantly (p<0.05) reduced by the cola beverage (VHN 262.13 ± 20.34), and significantly (p<0.05) increased after intraoral exposure for one hour (VHN 299.75 ± 26.86) and twenty-four hours (VHN 328.00 ± 18.70). The difference in the microhardness between the twenty-four-hour group and the forty-eight-hour group (VHN 333.50 ± 15.13) was not significant (p>0.05). The microhardness value of the forty-eight-hour group was significantly less than the values recorded during the initial pre-study measurements p<0.05).
