Abstract

Introduction In aesthetic dentistry, resin composites are one of the most popular materials due to their excellent aesthetic properties, their ability to be bonded to dentin or enamel and their adequate strength. They are polymeric materials which are highly cross linked and reinforced by crystalline or resin filler particles, dispersion of glass, or short fibres bound to the matrix by silane coupling agents

Materials And Methods Ten pellets of self-cure (dpi) were prepared with unified shape, diameter and thickness (10 x 10 x 4 mm). The heat-cured acrylic resin material was packed into silicone molds invested with dental stone inside denture flasks.. then, cured according to the manufacturer’s instructions in the curing unit. Then, one surface of each specimen was finished using metal burs and stone wheel finishing burs mounted on a slow speed handpiece. Later, it was polished using poly buff brushes and polishing paste followed by a wet rag wheel with a slurry of pumice.

Results The mean value of flexural strength before thermocycling(group 1)was found to be 82.2 mm while after thermocycling was found to be 97.61mm and the mean value of flexural strength before thermocycling(group2)was found to be 127.5mm while after thermocycling was found to be 158.4mm.

Conclusion The results from this study, depicts  that the self-cure resin after thermocycling showed enhanced flexural strength rather than the before thermocycling. Hence, the resin after thermocycling is more promising than the resin before thermocycling.
