چکیده مقاله:

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 shade,  2m2, in different thicknesses (0.5, 1, 2 and3 mm) using FTIR. The light curing unit used was Optilux 501, with an intensity of 600 mW/cm2 and exposure duration of 40 seconds. Three specimens of each cement group were examined in each condition. The obtained data was submitted to Kolmogorov-Smirnov and also checked for absence of skewness and kurtosis for normal distribution. After that, ANOVA test was used for comparison between experimental groups (Tukey HSD). Results: In all the three used cements, DC decreased as ceramic thickness increased. This reduction was not significant when using 0.5 and 1 mm ceramic discs, however, it was significant between 1, 2, and 3mm discs(p

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...

A critical analysis of the degree of conversion of resin-based luting cements

OBJECTIVE This study analyzed the degree of conversion (DC%) of four resin-based cements (All Ceram, Enforce, Rely X ARC and Variolink II) activated by two modes (chemical and dual), and evaluated the decrease of DC% in the dual mode promoted by the interposition of a 2.0-mm-thick IPS Empress 2 disc. MATERIAL AND METHODS In the chemical activation, the resin-based cements were prepared by mix...
