We present an algorithm that models stained glass in a physicallyrealistic manner. Stained glass is made by melting glass material with metal oxides that determine the color. Metal oxides are scattered in the glass, and we model it by distributing metal oxides in the volume defined by the glass. We render our stained glass model using a modified photon mapping. Our model is capable of modeling ...

Background and Aim: the study of antibacterial properties of resin cements and modified glass ionomers is of great importance. The aim of this study was to determine the antibacterial effect of resin-modified glass ionomers and resin cements on cariogenic bacteria, Streptococcus mutans, Streptococcus sabrinus and Lactobacillus acidophilus. Materials and Methods:In this experimental laboratory s...

This article is an updated review of the published literature on glass-ionomer cements and covers their structure, properties and clinical uses within dentistry, with an emphasis on findings from the last five years or so. Glass-ionomers are shown to set by an acid-base reaction within 2-3 min and to form hard, reasonably strong materials with acceptable appearance. They release fluoride and ar...

AIM The purpose of this study is to evaluate the clinical performance of three different restorative materials in primary teeth according to the FDI criteria. MATERIALS AND METHODS Resin-modified glass ionomer cement, compomer and composite resin restorations (n=93) were made in 31 patients. The restorations were clinically evaluated at baseline, 6th, 12th and 18th month with the FDI criteria...
