Abstract

The aim of this study was to evaluate the effects of three esthetic treatments (bleaching, polishing and brushing) on the microhardness and surface roughness of the teeth treated with (Icon) at different storage times (one day, one week and one month). White spot lesion was created on the labial surfaces of 120 anterior teeth were prepared, treated with Icon resin, divided into 4groups according to the treatment where, three subgroups were treated with polishing, bleaching and brushing at different storage times. Microhardness and surface roughness were measured. Results: There was a decrease in the microhardness and an increase in the surface roughness comparing with the control group specially in the polishing subgroup and after one month of storage. Conclusion: esthetic treatment affects the microhardness and surface roughness of Icon treated teeth. Polishing has highest effect while, brushing has the lowest. This effect increases with storage.
