Comparison of the microshear bond strength of feldspathic porcelain to enamel with three luting resins.

PURPOSE The purpose of this study was to compare microshear bond strength of three different luting resins using a new microshear method closely simulating clinical condition. METHODS Thirty 1-mm-thick slices of intact human first molars and thirty 0.8-mm-diameter feldspathic porcelain rods were etched by 37% phosphoric acid for enamels and 9.5% hydrofluoric acid for porcelains.

Adhesion in vitro of oral streptococci to porcelain, composite resin cement and human enamel.

We investigated the initial adhesion in vitro of oral streptococci to porcelain inlays. Four strains of streptococci, Streptococcus mitis NCTC12261, Streptococcus oralis ATCC9811, Streptococcus sanguis ATCC10556 and Streptococcus sobrinus OMZ176, were used in this study. The disc specimens were made of porcelain, composite resin cement and human enamel. These specimens, with or without a saliva...
