This aim was to assess the biomechanical and biocompatibility properties of novel glassfibre-reinforced com-posites (FRCs) with afluorinated urethane dimethacrylate (FUDMA) resin. Three ratios of FUDMA/TEGDMArn(30/70wt%, 50/50wt%, 70/30wt%) and two ratios of control FRCs withbis-GMA/TEGDMA (50/50wt% andrn70/30wt%) containing long silanized E-glassfibres were prepared. Despite 70wt%bis-GMA-FRC showed arnsignificantly higherflexural strength (p< 0.05), 50wt% FUDMA- andbis-GMA-FRCs were not differ from eachrnother. The greatest surface hardness and weight increase after water storage were found in 70wt% and 30wt%rnFUDMA-FRCs, respectively. No significant difference was found in water sorption and solubility among allrngroups. Average surface roughness was 1.80 ± 0.05μm, while 70wt% FUDMA-FRC exhibited the greatestrncontact angle (p> 0.05). Viabilities and ALP activities of MC3TC-E1 cells in all FUDMA-FRCs were higher thanrnbis-GMA-FRCs after 5 days. To conclude, the novel FUDMA-FRCs are potential substitutes that exhibited superiorrncytocompatibility properties but comparable biomechanical properties tobis-GMA-FRCs.
