Effect of Certain Denture Disinfectants on Surface Topography, Microhardness and Dimensional Stability of CAD/CAM Milled Polymethyl Methacrylate and Polyether Ether Ketone Denture Base Materials
Sponsor: Menoufia University
Summary
This study aims to evaluate and compare the influence of different denture cleansing methods using 1% sodium hypochlorite solution, 0.2% chlorhexidine solution and effervescent alkaline peroxide tablet solution -according to manufacturer's instructions- on surface roughness , microhardness and dimensional stability (%) of CAD-CAM Milled both Polymethyl methacrylate and Polyether Ether Ketone denture base materials.
