PURPOSE The purpose of this in vitro research project was to evaluate and compare the wear behavior of human tooth enamel opposing monolithic zirconia and other different ceramic restorative materials and also to observe the tetragonal to monoclinic phase transformation in zirconia-based ceramics that may occur while simulating wear occurring at room temperature in a wet environment. MATERIAL...
Abstract Background & aim: There are so many studies about effect of colored drinks and mouthwashes on discoloration of different dental ceramics. However, little is known regarding the effect of colored drinks on discoloration of monolithic zirconia .The purpose of this invitro study was to evaluate the effect of different surface treament methods on color stability of monolithic zirconia....
STATEMENT OF PROBLEM Streptococcus mutans can adhere at restored tooth margins to cause recurrent caries. Limited information about surface quality and bacterial adherence is available for lithium disilicate ceramic materials. PURPOSE The purpose of this in vitro study was to investigate how bacterial adherence is influenced by commercially available preparations of lithium disilicate ceramic...
The color of 7 composite resins, an unfilled restorative resin, and 3 glaze coatings was determined by reflection spectrophotometry and visually with Munsell color tabs. Statistically significant correlations existed between comparable parameters of the spectrophotometric and Munsell data. There was observable color variations among the 11 resins studied, but only 3 materials were within the ra...
The Linfen kiln complex, one of the most representative Shanxi kilns, is famous for its oil spotted glazed ware production. In this work, micro-Raman spectroscopy was applied to analyze nature rusty spot pattern a bowl fragment from kilns. Crystals polygonal shape found in spots at glaze surface and around bubbles cross-section were identified as hematite. Their distribution suggests that nucle...
