Effect of Probiotic Mouthrinses on Surface Microhardness of Esthetic Restorative Materials.

There is lack of studies that investigated the effect of probiotics mouthrinses on the surface properties of restorative materials. This study showed evidence that some of the tested probiotic mouthrinses in this study decreased the microhardness of the tested tooth-colored restorative materials after immersion for 21 and 63 minutes which is equivalent to 3 and 9 weeks of everyday use.
