This study was conducted to investigate the effect of surface treatment on bond strength of resin composite bonded to occlusal surface of abrasion-resistant plastic denture tooth. Nine different surface treatment methods for the occlusal surface were evaluated using the compressive shear bond strength test. Specimens without surface treatment have significantly lower bond strength than specimens treated with seven surface treatment methods (p<0.05), and showed interface failure after the test. Specimens treated with 5% hydrofluoric acid treatment +bonding agent treatment, sand-blasting treatment +bonding agent treatment, and sand-blasting treatment+5% hydrofluoric acid treatment+bonding agent treatment methods showed significantly higher bond strength than specimens treated by other treatment methods (p<0.05) and showed cohesive failure after the test.
