Title

BOND STRENGTH OF COMPOSITE RESIN TO ENAMEL: ASSESSMENT OF TWO ETHANOL WET-BONDING TECHNIQUES

Pages

  150-160

Abstract

 Objective: ETHANOL WET-BONDING (EWB) technique has been stated to decrease degradation of resin-dentin bond. This study evaluated the effect of two EWB techniques on COMPOSITE RESIN-to-enamel BOND STRENGTH.Materials and Methods: Silicon carbide papers were used to produce flat ENAMEL surfaces on the buccal faces of forty-five molars. OptiBond FL (OFL) adhesive was applied on ENAMEL surfaces in three groups of 15 namely: 1. ENAMEL surface and OFL (control); 2. Protocol 1 of the EWB technique: absolute ethanol was applied to water-saturated acid-etched ENAMEL surfaces for 1 minute before the application of ethanol-solvated hydrophobic adhesive resin of OFL 3 times; 3. Protocol 2: progressive ethanol replacement; water was gradually removed from the ENAMEL matrix using ascending ethanol concentrations before OFL application.Composite build-ups were made and the specimens were stored for 24 hours at 37°C and 100% relative humidity. Shear BOND STRENGTH test was performed using a universal testing machine at 1 mm/min crosshead speed. Fracture patterns were evaluated microscopically. Data were analyzed with one-way ANOVA and Fisher’s exact test (a=0.05).Results: There were no significant differences in BOND STRENGTH between the groups (P=0.73). However, regarding failure patterns, the highest cohesive ENAMEL fractures were recorded in groups 2 and 3.Conclusion: In this study, although both methods of EWB did not influence immediate BOND STRENGTH of COMPOSITE RESIN to ENAMEL, the majority of failure patterns occurred cohesively in ENAMEL.
