Effects of bleaching agents on surface roughness of filling materials

Effects of bleaching agents on surface roughness of filling materials

The aim of this study was to use a non-tactile optical measurement system to assess the effects of three bleaching agents’ concentrations on the surface roughness of dental restoration materials. Two composites (Grandio, Venus) and one glass ionomer cement (Ketac Fil Plus) were used in this in vitro...

Zusammenfassung:The aim of this study was to use a non-tactile optical measurement system to assess the effects of three bleaching agents’ concentrations on the surface roughness of dental restoration materials. Two composites (Grandio, Venus) and one glass ionomer cement (Ketac Fil Plus) were used in this in vitro study. Specimens were treated with three different bleaching agents (16% and 22% carbamide peroxide (Polanight) and 38% hydrogen peroxide (Opalescence Boost)). Surface roughness was measured with an optical profilometer (Infinite Focus G3) before and after the bleaching treatment. Surface roughness increased in all tested specimens after bleaching treatment (p
