There are many concerns about the erosive effect of acidic beverage. In this study,
the erosive effect of bovine enamel caused by Pepsi-ColaR(pH 2.41) and
rehardening effect by intraoral exposure were determined by microhardness test and
SEM. The bovine enamel specimen was imbedded in 100ml Pepsi-ColaR
during 5 minutes and exposed to the intraoral environment with removable resin plate.
The microhardness test was performed after 1 hr, 24 hrs, and 48 hrs. The results
obtained from this study can be summarized as follows:
1. The microhardness value was significantly (p<0.05) reduced by cola beverage, and
significantly (p<0.05) increased after 1 hr and 24 hrs respectively.
2. The difference in the microhardness between 24 hrs group and 48 hrs group was
not significant (p>0.05) and microhardness value of 48 hrs group was significantly less
than that of initial group (p<0.05).
3. The erosive effect of cola beverage and remineralization effect by intraoral exposure
were visualized by the SEM photo. But, the enamel surfaces did not return to their
original state.
