Effects of chemical composition on the corrosion of dental alloys
(Fundação Odontológica de Ribeirão Preto, 2012)
The aim of this study was to determine the effect of the oral environment on the corrosion of dental alloys with different compositions, using electrochemical methods. The corrosion rates were obtained from the current-potential ...
Microstructural study of the resistance to corrosion of laser welded AuPd alloy joints for prosthesis supported by implants
(Editora Unesp, 2002-01-01)
In this work, welded Au alloy joints, used for prosthesis supported by implants, have been studied before and after to laser welding processes. A refined dendritic microstructure was observed in the welding area. The base ...
Streptococcus mutans adhesion and releasing of metallic ions in dental alloys
(Faculdade de Odontologia de Piracicaba - UNICAMP, 2015-03-01)
AIM: To evaluate the adherence of Streptococcus mutans to the surface of the amalgam and copper/aluminum alloy samples and also evaluate the release of metallic ions. METHODS: The prepared medium was changed every 72 h and ...
Inhibition of demineralization in vitro around amalgam restorations
(1998-06-01)
Objective: The purpose of this in vitro study was to evaluate some forms of preventing or avoiding demineralization within enamel cavity walls adjacent to amalgam restorations. Method and materials: Third molar teeth were ...
