| Abstract | ||
| Aims: To evaluate the effect of adding different types and concentrations of polymers on the water solubility of heat cured acrylic resin. Materials and Methods: Heat cured acrylic resin specimens were prepared and divided into: Control group (without additives) and experimental group (with additives). Three kinds of additives (Styrene Butadiene Rubber (SBR), Poly ethylene glycol (PEG) and Poly urethane (PU)) were incorporated with acrylic resin in three concentration s 1%, 3% and 5% by weight. The water solubility was tested, calculated and the data were statistically analyzed by SPSS Version 19 by mean of Descriptive statistics, analysis of Variance (ANOVA), and Duncan multiple range tests at p ≤ 0.05. Results: The results showed that the water solubility of experimental group was less than that of the control group and its values decreased as the additives concentration increased. The lowest mean value of water solubility was achieved by the incorporation of SBR polymer at 5% concentration (0.018 μg/mm3). Conclusions: The type and concentration of additives directly affected the water solubility of heat cured acrylic resin. The control group has higher mean value of water solubility than that the experimental group. The additives were significantly decreased the amount of water solubility of heat cured denture base resin. | ||
