Abstract :

Aim: The aim of the present study was to evaluate the effect of two types of mouthwashes (non–alcoholic �lacalutaktiv, chlorhexidine 0.12%: Curasept" and alcoholic �26.9%� �Listerine") on color stability and surface roughness of two types of resin–based composites (nanofiller �filtek Z350� and microhyide �Glacier�). Materials and Methods: One hundred twelve standardized cylindrical test specimens of the studied material were prepared with dimension of (10 mm diameter x 2 mm thickness) by cylindrical ass mold then the specimens were randomly assigned into two main groups according to the type of resin–based composites. Then each main group was subdivided into eight subgroups according to the types of treatment solution used, and all sample subgroups were then immersed in 15 ml of distilled water for 24 hours at 37� C and under 100%humidity in an incubator, prior to baseline assessment; The color was measured by the digital spectrophotometer and the surface roughness was measured by surface roughness tester (surface roughness gauge); After that, specimens were immersed in 15 ml of the staining solution stored in a dark container which was then put in incubator at 37�C for 12 hours, which is equivalent in time, to 1 year of 2 min. daily use of mouth wash. After immersing it in mouthwashes, the second measurement for color stability and surface roughness was done. Results: The results showed that immersion in staining solutions produce statistically significant increase in color change and surface roughness for both types of resin–based composites. Conclusions: Immersion into all the staining solutions (Listerine �26.9%� �alcoholic�, chlorhexidine and lacalute �nonalcoholic�) and distilled water are potential to stain and cause surface roughness of resin–based composites Listerine (alcoholic) mouthwash showed higher change in color and surface roughness in comparison to other groups and Glacier (microhyide) resin–based composites showed more color change and surface roughness compared to Z350 (nanofill) resin–based composites.
