Background: New types of artificial teeth are commercially available. However, evidence - based information with respect to their physicomechanical properties is lacking. Objective: The purpose of this study was to qualify and quantify relative micro hardness characteristics of three commercially available types of artificial teeth. Materials and Methods: Three brands of three types of artificial teeth were examined. Vickers hardness was determined for each of the polished cross-sectioned teeth. Results: Vicker hardness values ranged from 22.3 to 26.7 for microfilled composites,20.0 to 25.3 for dual cross linked acrylic __ampersandsignamp; 15.9 to 19.6 for nano- composite teeth. Conclusion: Within the limitations of this study, microfilled composite denture teeth exhibited superiority in terms of microhardness among all the specimens evaluated.
