In April 2016 Manchester eScholar was replaced by the University of Manchester’s new Research Information Management System, Pure. In the autumn the University’s research outputs will be available to search and browse via a new Research Portal. Until then the University’s full publication record can be accessed via a temporary portal and the old eScholar content is available to search and browse via this archive.

Abstract

ABSTRACT: Purpose: To compare the bond strength to human dentin for a variety of adhesive materials, including self-adhesive resin composites, self-etch and etch-and-rinse adhesive systems and glass-ionomer cement by means of micro shear bond strength (μSBS) test and SEM observations. METHODS: Seventy-two human molars were sectioned to obtain a 2 mm-thick slab of mid-coronal dentin and were subsequently randomly divided into nine groups (n = 8). Nine conical frustum-shaped build-ups were constructed on the occlusal surface of each dentin slab using bonding agents (Group 1: OptiBond FL; Group 2: OptiBond XTR) combined with a resin composite (Premise Flow), self-adhesive resin composites (Group 3: RelyX Unicem; Group 4: RelyX Unicem 2; Group 5: SmartCem2; Group 6: SpeedCEM; Group 7: Maxcem Elite; Group 8: Vertise Flow) and a glass-ionomer cement (Group 9: Ketac-Fil). Specimens were subjected to μSBS test and observed with SEM. Data were analyzed by a mixed model and chi-square test. RESULTS: The bond strengths measured in Groups 3-9 were significantly lower than those recorded in Groups 1 and 2. There were no significant differences in bond strengths between Groups 1 and 2 or between Groups 4 through 8. The bond strength measured in Group 9 was significantly lower than those recorded in Groups 4, 5, and 6 but was not significantly different than those recorded in Groups 3, 7, and 8. Failures were mainly adhesive in all groups.
