 We conducted a study to compare the shear bond strength, SBS, of two peak composites, BioHPP and BioHPP+, with three different veneering composites, Vizio.Line, SRnexco, and VitaVMLC. The surfaces of each composite were treated differently prior to testing. Untreated BioHPP and BioHPP+, had the highest roughness, while the sandblasted BioHPP+, had the lowest. The sandblasted BioHPP+, also had the highest hydrophobicity, while the untreated BioHPP had the highest hydrophilia. The highest SBS was achieved by using BioHPP and Vizio.Line with VitaVMLC, followed by BioHPP+, and Vizio.Line with SRnexco, and then BioHPP+, and Vizio.Line with MKZ Primer.
