Optical properties, surface roughness, and bacterial adhesion of feldspathic CAD/CAM ceramic material after immersion in staining media with different pH (opens in new tab)

This study aimed to evaluate the effects of acidic and alkaline staining solutions on the optical-mechanical properties of feldspathic (Vitablocs Mark II) Computer-aided design/computer-aided manufacturing (CAD/CAM) ceramic materials after 4 weeks of immersion in media. Specifically, this investigation focused on assessing mean colour change (ΔE*), the translucency parameter (TP00), the opalescence parameter (OPBW), surface roughness, and bacterial adhesion by colony-forming unit (CFU) count....
