OBJECTIVES The aim of this study was to evaluate the influence of two adhesive systems and the post space region on the degree of conversion of dual resin cement and its bond strength to root dentin. MATERIAL AND METHODS One three-step etch-and-rinse (All-bond 2, Bisco) and another one-step self-etch (Xeno III, Dentsply) adhesive systems were applied on 20 (n=10) crownless bovine incisors, at...

The experimental work herein reported tends to justify our hypothesis recently expressed, that the common failure of antibacterial serums to combat active infections when passively transferred to a normal animal, is due not so much to a lack of suitable or sufficient antibodies as to absence of cell preparation or mobilization in the recipient. In the case of experimental streptococcus empyema ...

BACKGROUND This paper discusses the treatment protocol for patients with frostbite. METHODS We performed a retrospective analysis of a series of 17 patients with second- and higher-degree frostbite who had been treated at our medical institution between 2010 and 2012. RESULTS Our clinical series of patients (n=17) included 13 men and four women, whose mean age was 42.4±11.6 years (range, 22...

A quantitative model is presented to describe the formation of volume holograms in a polymeric medium containing photopolymerizable acrylate monomers that undergo spatially modulated gelation as a result of exposure to a visible ‘‘write’’ beam. The model refines the simple diffusion model of Zhao and Mouroulis @J. Mod. Opt. 41, 1929 ~1994!#, by including cure dependence of both the photoreactio...

compare the effect of different ceramic thicknesses on degree of conversion (dc) of 3 light-cured resin cements. methods: in this experimental in-vitro study, the degree of conversion of three light-cured resin cements, variolink veneer (ivoclar, liechtenstein), relyx veneer (3m espe, usa) and choice2 (bisco, usa) were evaluated beneath feldespatic ceramic discs (vita vmk master) with a same sh...
