Abstract

Background and Aims: A suitable restorative material must have acceptable mechanical properties. The aim of this study was to evaluate the effect of conventional acidic drinks on the Micro-hardness of two dental resins. Materials and Methods: 48 samples of each of P60 and G-aenial composites were prepared and randomly divided into six groups: Coca-Cola, Fanta, yoghurt drinks, soft beer, Sprites and control groups. The study was in 3 steps: after one day in distilled water and after one day and one week of immersion in beverages per day (6 hours). The Vickers Micro-hardness was then evaluated. Finally, data were analyzed by, t-tests, ANOVA and Tukey tests. Resultes: Comparing the results between the two groups, a significant difference between the two composite was found. After one day in the water, the average Micro-hardness for P60 was of 27. 12 (kgf/mm2) and 16. 51 (kgf/mm2) for G-aenial amount and these differences were found statistically significant (P=0. 0001). For the 6-hour maintenance interval, the average Micro-hardness between P60 and G-aenial was statistically significant (P=0. 0001). For 42 hours, the average Micro-hardness ranged between P60 and G-aenial that were statistically significant (P=0. 0004). The stiffness of the P60 composite after 42 hours’ storage in soft beer significantly decreased compared with the control group (P=0. 03). G-aenial composite hardness after 42 hours of soaking in the Coca-Cola was reduced significantly compared to yogurt drinks (P=0. 02). Conclusion: As a result, the hardness of P60 composite was higher than that of G-aenial. The hardness of both composites reduced in acidic drinks after one week.
