ABSTRACT

Aim To evaluate the radiopacity and properties of self cure acrylic resin in combination with different proportions of calcium carbonate. Materials and methods A total of 27 samples of self cure acrylic resin (pink colour DPI- RR) was fabricated of the size 4 X 3 X 3 mm. Three samples were present to each group. Calcium carbonate was added in various proportions to the three groups. Independent variables were the powder to liquid ratios. Dependent variables were the dough forming time, setting time, compressive strength and radio-opacity. Results Maximum radio-opacity was seen in 3:1 P/L with maximum calcium carbonate in all the different powder liquid ratios. Compressive strength increased after addition of calcium carbonate. Conclusion The results of the present study conclude that calcium carbonate provides evident radiopacity to the self cure acrylic resin. Furthermore, the concentration of calcium carbonate also affects the intensity of radiopacity. It was found that higher concentrations produce a higher degree of radiopacity. Keywords: Self-cure acrylic resin (pink), calcium carbonate, radiopacity, compressive strength, dough forming time
