Abstract :Objective: Many factors in the mouth affect the clinical lifetime of materials. Acids, enzymes, acidic properties of food and beverages formed in the plaque could change the physicochemical properties of restorative materials. The aim of the study is to examine the effect of acidic beverages on the microhardness of alkasites, and conventional glass ionomers, with changes in surface coating applications. Materials and Methods: Forty specimens in eight mm diameter and two mm thick discs were made with each Cention N and Ionofil U. Half of the specimens were covered with surface sealant. In each of the four subgroups: cola, orange juice, sparkling mineral water and distilled water, 10 discs were stored for 5 minutes, three times a day for a week. Microhardness measurements were made after they were kept in an acidic environment. Results: Acidic beverages significantly reduce the microhardness of restorative materials. The highest microhardness value was observed in the Cention N group with surface sealant. The lowest microhardness value was observed in the Ionofil restorative material group without sealant. Conclusion: The acidic agents tested (cola, orange juice, and sparkling mineral water) have an effect on the reduction of surface microhardness of restorative materials. For clinical decision-making, Cention N is the most suitable material for restorations in patients who are at high risk for erosive conditions.
