Abstract: The effects of tooth brushing could affect the long-term esthetic outcome of composite restorations. This study evaluated the effect of two different emission spectrum light-curing units on the surface roughness. roughness profile. topography and microhardness of bulk-fill composites after in vitro toothbrushing. https://www.ealisboa.com/flash-grab-Hellfire-Sloe-Gin-special-find/
