Comparison Of The Influence Of 3 Types Of Denture Cleanser On Color Change Of Acrylic Resin Of Denture Base

Color stability is an important property of denture base acrylic resin. 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. 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. The difference between 5.25% sodium Hypochloride and other cleansers in terms of color changes was statistically significant (p<0.001). The Corega tablet solution demonstrated a greater effect on color changes of coarse surfaced acrylic resins compared to smooth surfaced resins. Use of 5.25% sodium hypoclorite cleaner will lead to a higher degree of color change in acrylic resins. In addition, the cleaners demonstrate a greater effect on coarse surfaces compared to smooth ones.
