Abstract:Objective: To investigate the biological effect of a new method to camouflage the cobalt-chromium (CoCr) metal structure of an RPD, onto which an electrostatic paint was applied. Methods: In vitro cytotoxicity of epoxy Politherm NOBAC30C (Weg Industries SA, Santa Catarina, Brazil) in combination with polished CoCr was tested by placing it in contact with cultured human fibroblasts and comparing it with polystyrene (control surface). The cells were cultured in the presence of the test surfaces for 24, 48, 72… Show more
