ABSTRACT

Several studies have reported the erosive power of soft drinks on different direct filling materials, as well as in the tooth enamel. The purpose of this study was to determine if there were changes in the superficial hardness of different commercial resins (microhybrid and nanocomposite) after the action of a carbonated drink (Cola Drink). Ten samples of every brand of composite (Tetric Evo Ceram; Filtek Z250, Filtek Z350, Filtek P60, Filtek Supreme XT, and Premisa) were tested. The microhardness of the resins was measured with a Hardness Tester. The samples were submitted to alternate immersion in the carbonated drink for 7 days. At the end of the test, the final microhardness was measured. One Way Analysis of Variance with Tukey’s Post Hoc Test and Student’s t-Test were used to compare if there were variations in the microhardness among the samples. A significant decrease in the superficial microhardness was found in all the resins except in Tetric Evo Ceram.
