Background: This study was conducted to compare the color stability of heat cure acrylic resin after immersion in distilled water and denture cleansers such as fittydent, dentipur denture cleanser. Materials and Methods: It consisted of fourty rectangular shaped specimens; divided in four groups. Group I contained10 specimens which were measured at baseline (control group) of the study (0 day), group II consisted of 1o specimens which were immersed in distilled water. Group III consisted of 10 specimen immersed in Fittydent denture cleanser tablets for 10 minutes and group IV contained 10 specimen immersed in Dentipur denture cleanser tablets for 10 minutes. Specimens were polished and stored in distilled water for 24 hours prior to experiment. After 60 days of immersion, the specimens were tested for color changes with spectrophotometer. Results: There was statistically significant difference in the color change (∆E) among all groups (p < 0.001) after 60 days of immersion. At baseline (0 day), trace amount of color change was observed whereas when specimens were immersed in Fittydent denture cleansers tablets for 60 days noticeable change in color was observed. Very slight change in color was observed when specimens were immersed in distilled water and dentipur denture cleanser solution. Conclusion: Author concluded that the color stability of denture base acrylic resin was influenced by the type of denture cleansers used.
