Comparative evalutation of effect of different mouthwashes on color stability of different composites- an vitro study.

Abstract- Background- Color is the important property for the restorative materials to have long-term durability in the oral cavity. Color is important in aesthetics, characterizing and personalizing a smile. Aim- The aim of this study was to evaluate the effects of five commercially available mouthrinses (Listerine, Colgate plax, Clohex Plus, Orahex Plus and Senquel-AD) on color stability of three different resin-based composite restorative materials. Material and Methods - A custom made stainless steel split mold was used for fabrication of  forty-eight samples of each composite resin material (Durafill VS, Z100, Filtek Z350 XT). The samples were immersed in distilled water after curing for 24 hours. Baseline measurements for Color stability were taken. After that, each group was immersed in 20 ml of assigned mouthrinse solutions and incubated at 37° C for 24 hours. The samples were resubjected to Color stability tests. The change in color difference was calculated. Statistical analysis- Result- The results revealed that all mouthrinses tested changed the color of the composite resins. Conclusions- It may be concluded that the effect was both mouthrinse and material dependent.
