Effects of immersion in various beverages, polishing and bleaching systems on surface roughness and microhardness of CAD/CAM restorative materials.

ABSTRACT:

Background

The aim of this study was to investigate the effect of an immune-boosting beverage with Sambucus nigra (SAM), an energy beverage (ENE), an in-office bleaching agent with a novel composition, and a fine-grain professional dental prophylaxis (PDP) paste on the surface roughness (Ra) and microhardness (MH) of CAD/CAM restorative materials over time.

Methods

Feldspathic ceramic (FC) and polymer infiltrated ceramic network (PICN) specimens were prepared (N = 126). Glazing, polishing, bleaching and immersion in beverages groups were formed. Bleaching gel containing 25% Hydrogen Peroxide Superior was applied to the specimens with a bleaching pen. Ra and MH were measured at five time points of baseline, days 1, 14, 28 and after PDP.
