Abstract:The usage of fiber ت reinforced composite in dentistry, is increasing. This is basically to the restriction provided by other material, used in dentistry. One of the most important clinical property, is flextural strength. As a result, the purpose of this study was to determine the effect of pre تimpregnation on flextural strength of one type of composite, Dialog.Method & Material:- 4 groups, each containing 12 samples, a total of 48 numbers, were put in a mold made of plexi ت glass. These groups were, Non-impregnated, pre-impregnated , both mesh and bond and a control group containing no fibers. They were then kept in 37 ░ c for 48 hours in water and were put under a force of 20 N with a speed of 1 mm/ . The flextural strength of the samples were calculated. By ANOVA and Duncan their comparison was performed. Results:- According to test result, the pre-impregnated bond type had the greatest flextural strength. But no significant statistical difference was seen between this groups and the other, No fibers, and non-impregnated. on the other hand the mean flextural strength of pre-impregnated, mesh type, was the lowest of all. Discussion:: - According to the result of this study, and previous studies, Due to a very low flextural strength of pre-impregnated, mesh typc, It's suggested to use pre impregnated, bond type in bridge preparation..
