The Effect Of Staining And Bleaching On The Microhardness, Surface Roughness And Color Of Different Composite Resins

Özcan KARATAŞ

Background: There are studies that examined the effect of staining on the surface properties of composite resins, using different solutions and bleaching applications. However, the effect of both staining and bleaching on the same composite specimens is an issue that needs to be investigated. Objectives: The aim of this study was to investigate the surface microhardness, roughness and color changes (ΔE) of 2 different composite resins after staining and bleaching. Material and methods: A microhybrid and a nanohybrid composite were used in the study. One hundred and fifty specimens were prepare ...Daha fazlası
