Background: Whey protein supplements might be a potential risk factor for the restoration surface due to its pH and lactose content. Aim: The study aimed to evaluate the effect of whey protein beverages on the microhardness of four restorative composites with different microstructures (Filtek Z 350XT, Filtek Z 250XT, Filtek Bulk Fill (FBF), and Filtek P 60). Materials and Methodology: Forty disc-shaped samples from each material (in total 160) were prepared and wet polished. The samples of each group were randomly divided into four subgroups and subjected to four immersion media namely, whey protein Concentrate (WPC), whey protein Isolate (WPI), whey protein water (WPW), and distilled water (DW). The immersion protocol was performed twice for 10 min daily for 30 days followed by immersion in artificial saliva for another 10 min and stored in DW till the next cycle. The pre immersion and post immersion microhardness of all the samples were recorded with a Microhardness Tester FM-800. Data obtained were statistically analyzed using SPSS 25 software. Results and Conclusions: All composites exhibited decline in microhardness, except for FBF. P 60 composites which showed the highest decline in microhardness. WPC and WPI caused the greatest reduction in microhardness compared to WPW.
