Objective: This study evaluated the clinical effectiveness of two exposure times of microwave irradiation on the disinfection of complete dentures.Methods: Biofilm samples were collected from dentures of 30 patients, who ...
Synthesis of wurtzite ZnS nanoparticles using the microwave assisted solvothermal method
(2013-04-15)
In this article, we report the development of an efficient and rapid microwave assisted solvothermal (MAS) method to prepare wurtzite ZnS nanoparticles at 413 K using different precursors. The materials obtained were ...
Influence of microwave energy on structural and photoluminescent behavior of CaTiO3 powders
(Elsevier B.V., 2008-08-01)
Calcium titanate, CaTiO3 powders were prepared by the polymeric precursor method and annealed at different temperatures for 2 h in a conventional furnace and for 30 min on an adapted microwave oven. The effect of microwave ...
SnO 2 ceramics with low electrical resistivity obtained by microwave sintering
(2011-08-01)
The main aim of this study was to develop dense and conducting SnO 2 ceramics without precipitated phases on the grain boundaries, which was verified using field emission scanning microscopy (FE-SEM) coupled with an ...
Investigation of microwave dielectric relaxation solid state process in the antiferroelectric phase of NaNbO3 ceramics
(Elsevier B.V., 2004-08-01)
This letter reports microwave dielectric measurements performed in the antiferroelectric phase of NaNbO3 ceramics from 100 to 450 K. Remarkable dielectric relaxation was found within the antiferroelectric phase and in the ...
Decalcification dynamic of dog mineralized tissue by microwaves
(2007-06-01)
The aim of this article is to present the decalcification process dynamic of mineralized tissue in dogs, teeth and jaw, comparing the traditional decalcification method, immersion, and microwave, immersion followed by ...
Growth of Candida species on complete dentures: effect of microwave disinfection
(Wiley-Blackwell Publishing, Inc, 2009-03-01)
Microwave disinfection of complete dentures has been recommended to treat denture stomatitis in non-immune compromised patients. Oral candidiasis is a frequent manifestation of HIV infection. The objective of this study ...
Influence of Microwave Disinfection on the Dimensional Stability of Denture Reline Polymers
(Wiley-Blackwell, 2010-07-01)
Purpose: The purpose of this study was to evaluate the effect of microwave disinfection (3 minutes at 650 W) on the dimensional stability of hard chairside reline resins (Kooliner, Tokuyama Rebase II, Ufi Gel hard, New ...
