Objectives: The purpose of this investigation was to evaluate the effect of different denture cleansers on surface roughness of heat cure acrylic dentures. Materials and Method: Denture base resin material heat cure resin was immersed for 120 days in commercially available two denture cleansers (Group 1-sodium perborate, Group 2-sodium hypochlorite and Group 3-control). Surface roughness and hardness were measured for each sample before and after immersion procedure. Results: Heat cure resin immersed in sodium hypochlorite and sodium perborate showed a change in surface roughness of (0.29um) and (0.16) respectively. Heat cure resin immersed in sodium hypochlorite and sodium perborate showed change in surface hardness of (0.10 and 0.24)respectively. It was found heat cure resin immersed in sodium hypochlorite showed maximum change in surface roughness and heat cure immersed in sodium perborate showed a maximum change in hardness. The surface roughness and hardness of heat cure acrylic dentures was increased significantly by chemical solutions of denture cleansers. Conclusion: Surface roughness change of heat cure resin was not within the clinically accepted range of surface roughness. Denture cleansers can considerably alter the surface roughness and hardness of denture base resins and should be used carefully depending on the material.
