Influence of Investment, Disinfection, and Storage on the Microhardness of Ocular Resins
(Wiley-Blackwell, 2009-01-01)
Purpose: The longevity of an ocular prosthesis is directly related to the resistance to erosion of its material. The purpose of this study was to evaluate the effects of chemical disinfection and the method of investment ...
Microhardness change of enamel due to bleaching with in-office bleaching gels of different acidity
(Informa Healthcare, 2012-03-01)
Objective. The aim of this study was to assess the enamel microhardness treated with three in-office bleaching agents, containing 35% hydrogen peroxide with different acidity. Materials and methods. Bovine incisors were ...
Disinfection of Bovine Enamel by Microwave Irradiation: Effect on the Surface Microhardness and Demineralization/Remineralization Processes
(Karger, 2010-01-01)
Enamel specimens need to be disinfected before being used in intraoral appliances and the disinfection method must not affect the integrity of the tooth. This study evaluated the effectiveness of microwave bovine enamel ...
