We investigated the influence of post cure heating on the flexure strength of the prosthetic composite resins GRADIA, SOLIDEX, Epricord, ARTGLASS, Sculpture, Targis and ESTENIA. Specimens were fabricated either with light curing only or with light curing and post cure heating. Four specimens were fabricated with each of the materials. Three-point bending tests were performed at a crosshead speed of 0.5mm/min and a span length of 20mm. The data were analyzed using two-way analysis of variance (ANOVA). Incorporation of post cure heating resulted in a statistically significantly higher flexure strength compared with light curing only for all of the products. There was no interaction between curing condition and product. ESTENIA had the greatest flexure strength, followed by Targis, ARTGLASS, Sculpture, GRADIA, Epricord and SOLIDEX in that order. Flexure strength of all of the products was improved by post cure heating after light curing.
