In this study the “in vitro” effect of a carbonated beverage on the superficial microhardness of three restorative esthetic material for direct restorations, a microhybrid composite, a fluid composite and a restorations glass ionomer was analyzed. Eight 4mm diameter and 2mm high cylindrical blocks were elaborated of each material in study. Four of them were stored in an isotonic solution and taken as a control group. The four ones left were submitted to the effect of a carbonated beverage 10 minutes for 7 days at environmental temperature, and while the experiment wasn’t made they were stored in an isotonic solution at environmental temperature. An initial and final superficial microhardness measurement were made to analyze if there was any variation. To determinate if the variations found were significant, the T- STUDENT test were applied, and to compare variations between the three materials the ANOVA test were used. This study concluded that there were significant decrease on superficial microhardness of all tested materials submitted to the carbonated beverage effect. But despite of microhybrid composite shows a greater decrease than the other two materials the difference is not significant.
