EFFECT OF WHITENING MOUTHRINSES ON SURFACE ROUGHNESS OF COMPOSITE RESIN

Objective: the aim of this in vitro study was to evaluate the effect of whitening mount rinses on superficial roughness a nanofilled resin composite. methods: sixty-three nanofilled composite resin specimens (8 mm x 2 mm) were prepared and randomly divided into seven groups, according to the mouthrinse solutions (n = 9): oral-b 3d white, crest 3d white, colgate optik beyaz, scope white, signal white now and listerine whitening vibrant. the control group used in the study was distilled water. the initial surface roughness measurements (ra) were measured with a profilometer and then the each sample was immersed in 2 ml of the mouthrinses for 14 days period. after immersion period, roughness readings were repeated and the data were analyzed with anova and scheffe test (p<.05). results: the profilometric assessment showed that exposure to mouthrinse resulted in a slightly increase in roughness values in all groups. but, the differences between mouthrinses groups and the control group were not statistically significant (p > 0.05). conclusion: we conclude that the influence of the whitening mouthrinses on the surface roughness of dental resin composite was negligible.
