Effect of surface treatments and bonding type on elemental composition and bond strength of dentin.

The objective of this study was to explore the effect of different surface treatments and bonding types on elemental composition and bond strength of dentin. Under water cooling, 1.5 mm of tooth structure containing just dentin was cut from 39 extracted human molars.

Effects of 16% Carbamide Peroxide Bleaching on the Surface Properties of Glazed Glassy Matrix Ceramics.

Objective: To determine the influence of the home bleaching agent, Opalescence PF, on the surface roughness and microhardness of glazed glassy matrix CAD-CAM ceramics. . The 28 sintered leucite- and lithium disilicate-reinforced ceramic specimens (IPS Empress CAD and IPS e.

Evaluation of Flexural Strength of Different Denture Base Materials Reinforced with Different Nanoparticles.

Purpose: To evaluate the effect of adding Al O , SiO , and TiO nanoparticles in ratios of 1, 3, and 5 wt% to different acrylic resins on flexural strength.

Materials And Methods: A total of 210 specimens were prepared in 30 groups (n = 7/group) (Control, 1% Al O , 3% Al O , 5% Al O , 1% SiO , 3% SiO , 5% SiO , 1% TiO , 3% TiO , 5% TiO ). The specimens were polished with 200-, 400-, and 600-grit abrasive paper to provide a standard surface before testing and then suspended in distilled water for 30 days.

Effect of Home Bleaching on the Translucency of CAD/CAM Systems.

Purpose: To evaluate the effect of a home bleaching agent (Opalescence PF) on the translucency of CAD/CAM ceramic systems.

Materials And Methods: The 28 sintered ceramic specimens (IPS Empress CAD and IPS e.max CAD; 15 mm long, 10 mm wide, 1 mm thick) were divided into two subgroups as control and bleaching groups (n = 7).
