MATERIALS AND METHODS: One hundred sixty samples of five different brands of acrylic teeth were divided into four groups (untreated and treated groups each of these were cured by water bath or microwave techniques). The bond strength between acrylic tooth and denture base resin was measured in shear mode by using unconfined compression machine. The shear bond strength (SBS) in MPa was calculated, debonded surfaces were examined using visual examination and reflecting light microscope. Analysis of variance (ANOVA) and Duncan's multiple range tests were used for statistical analysis. RESULTS: there was a significant difference in bond strength of acrylic denture base to different tooth materials (P < 0.001). CONCLUSIONS: SBS of acrylic teeth treated by monomer surface treatment for 180 seconds to microwave cured resin was significantly higher than that of water-bath cured resin, and cross-linked acrylic teeth showed lowest SBS compared to other type of acrylic teeth.
