Resistance of composite and amalgam core foundations retained with and without pins and bonding agents.

To compare the resistance of different amalgam and composite core foundations retained by pins, bonding agents, or both, 100 molars were mounted in acrylic resin and their occlusal surfaces were reduced to expose dentin. Pins were inserted at the four line angles of the teeth and matrices were placed. Bonding agents were applied according to the manufacturers' instructions.

An evaluation of dentin conditioners for resin-modified glass ionomer cements.

This study sought to test the null hypothesis that there was no difference between three dentin conditioners in terms of how they affected the shear bond strength to dentin of three resin-modified glass ionomer (RMGI) cements. One hundred twenty caries-free third molars were mounted in acrylic resin and their occlusal surfaces were reduced to within 2 mm of their cemento-enamel junction (CEJ). Of the three cements tested, Rely-X Plus (22.
