ABSTRACT
Resin cements are used extensively in fixing prostheses because they have good mechanical properties. This study reviewed clinical application of three types of resin cements, resin cement with total etch adhesive system, resin cement with self etching system and self adhesive resin cement.Keywords: resin cement
ABSTRACT
The purpose of this study was to evaluate the mean shear bond strength between 3 systems of resin cements (total etch, self etch, self adhesive) and coronal dentin. The crowns of 40 extracted premolars were split longitudinally in buccolingual direction, and then split in mesiodistal direction (from DEJ 1 mm). The crowns were mounted in aluminum ring with self cure acrylic resin. Specimens were wet abraded with 600-grit SiC paper and randomly divided into 4 groups (n=20). Eighty cylinders were made with Z350 composite resin (Æ 2 mm., 3 mm. in thickness). Composite resin specimens were bonded with dentin specimens by using either resin cement Variolink® II (Group1), PanaviaTM F2.0 (Group2), RelyXTM U100 (Group3), and Multilink® sprint (Group4) strictly following manufacturer’s instructions. The specimens were stored in water at 37 ± 20C for 24 hours. The specimens were tested to failure by a Instron® universal testing machine at a crosshead speed of 0.5 mm./min. Shear bond strength data (MPa) were analyzed with one-way ANOVA and Tukey’s multiple comparison test (p0.05) but higher mean shear bond strengths(p
