Adhesion improvement via surface functionalization of epoxy-resin base post by low temperature plasma
© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. The adhesion between dental materials could be improved by an increase of interfacial polarity. In this study, low temperature plasma was used to treat an epoxy-based post. The surface modifications after treatment were characterized by X-ray...
