Color changes indicate aging or damaged dental materials. The purpose of this study was to determine the influence of 3 different types of denture cleansers on the color stability of acrylic resin.     Materials and Methods: This experimental study was performed on 40 samples fo 10×55 mm acrylic resins including 10 samples in the control group (BAYER) and 30 samples in the case group. Each group was then divided into 2 categories of smooth and coarse samples. Three cleanser solutions were then prepared as follows: 1. A 200 ml plate of 5.25% sodium hypochloride, 2. A 200 ml plate of varda + vinegar and 3. A 200 ml plate of water with a cleaner tablet named Corega. A spectrophotometer was used to record the initial and final color of each sample before and after placement in the cleaner solutions. Statistical data analysis was done using non parametric Kruskal- Wasliss AND Mann-Whitney Test.     Results: The difference between 5.25% sodium Hypochloride and other cleansers in terms of color changes was statistically significant ( p CP - IRAN IN - LG - eng PB - Res-Dent-Sci PG - 15 PT - original article YR - 2012
