摘要: This study sought to evaluate the pH value, film thickness, filler particle percentage, and morphological changes of self-adhesive resin luting cements. Products tested were G-Cem, Maxcem, Smart Cem, RelyX™ Unicem. Cement was measured with test paper. Filler percentage calculated after cement samples incinerated at 750°C. To mixed cements placed between two glass plates compressed using a loading device. For changes, specimen surfaces observed by SEM treatment various media. There significant differences among values 20 seconds light curing, 90 48 hours mixing. directly proportional thickness. Degradation also detected surface polishing immersion in water, acetic acid, acetone. In conclusion, found properties materials tested, these might lead their clinical performance.
