Effect of Accelerated Aging on the Sorption and Solubility Percentages of Silicone Facial Prostheses
| Resumo: | Objective This study aimed to evaluate the effect of accelerated aging on the sorption and solubility percentages of the MDX4-4210 and A-2186 silicones. Materials and Methods Two silicones (A-2186 and MDX4-4210) and three intrinsic pigments (bronze, black, and pink) were used in this study. Thus, six groups were created (n = 10): Group 1 = bronze MDX4-4210; Group 2 = black MDX4-4210; Group 3 = pink MDX4-4210; Group 4 = bronze A-2186; Group 5 = black A-2186; and Group 6 = pink A-2186. The dimensions of all samples were the same (45-mm diameter (o) × 1-mm thickness). The samples were aged for a total of 1,008 hours. In this period of 1,008 hours of accelerated aging, the sorption and solubility percentages of each sample were calculated at three time points (252, 504, and 1,008 hours). Statistical Analysis Three-way analysis of variance (ANOVA) and the Tukey test were performed (α = 0.05). Result Accelerated aging can significantly increase the sorption and solubility percentages of the MDX4-4210 and A-2186 silicones. |
