Effect of Chemical Disinfectants on Tenile Strength, Shore Hardness, and Color Stability of Acrylic Denture Base Material

The capability of disinfecting dental prostheses to rapidly inactivate pathogenic microorganisms without compromising the denture base resins is essential. The objective of this inquiry was to ascertain how chemical disinfectants affected the mechanical properties of acrylic base materials (shore hardness, tensile strength, and color stability) this investigation was carried out to establish a foundation for the comparison of tensile strength, shore hardness, and color stability tests of acrylic denture bases treated with disinfectants using 2% Glutaraldehyde, 4% chlorhexidine, and 5.25% sodium hypochlorite. Specimens were prepared according to all manufacturer recommendations. Before being submerged in the chemical disinfection, the samples were polished and then kept in distilled water at 37 degrees Celsius for about 50 plus or minus two hours. For each of the following alternatives, each sample was immersed for 10 minutes: 2% glutaraldehyde, 4% chlorhexidine gluconate, or 5% sodium hypochlorite. The samples were then immersed in water for a further three minutes. The disinfection procedures were repeated four times. The data was analyzed statistically using SPSS, which stands for Statistical Package for the Social Sciences. The ANOVA test was used to find statistically significant differences between the groups that were tested. For multiple comparisons between the control and experimental groups, the Dunnett test was utilized. The findings of this investigation indicate that the immersion of samples in disinfectant solutions does not induce any discernible alteration in the characteristics of acrylic, in contrast to the immersion of samples in distilled water. It may be concluded that the disinfectant solutions used were suitable for disinfection based on the findings of testing the mechanical qualities of the acrylic materials.
