Summary
The hardness of acrylic teeth and their wear re- teeth with adequate hardness is highly sistance can significantly affect the longevity and important.[2]The type of artificial teeth, diet, clinical service of dentures. The effect of nonalcoholic Listerine and CHX after thermocycling on the microhardness of acrylic denture teeth has not been evaluated. Materials and Methods: This in-vitro experimental study evaluated 26 size #11 mandibular central incisor Major Plus artificial acrylic teeth (Major Dental, Italy) that were randomly divided into three groups of 8 for immersion in 0.2% CHX (V-One, Tehran, Iran), alcohol-free Listerine (Johnson & Johnson, Sao Paulo, Brazil), and distilled water. The samples were immersed in the solutions for 120 minutes corresponding to 4 months of clinical service They were removed from the solutions twice daily, each time for 30 seconds, rinsed with distilled water, and placed again in the solutions.
