Data availability-BIOCOMPATIBILITY.xlsx

Two ratios of HDDMA/TEGDMA resin were researched: exp-1 (70/30 wt%) and exp-2 (50/50 wt%) with two bis-GMA resin control groups (bis-GMA/MMA and bis-GMA/TEGDMA resins, both 70/30 wt%). E-glass fibers were embedded into the resins to prepare FRCs specimens. Biocompatibility was assessed for cytotoviability and biofilm formation with Streptococcus mutans, Streptococcus sanguinis, Enterococcus faecalis, and Candida albicans. Biomechanical properties were evaluated for flexural strength and hardness (24 h, water storage 1 and 28 days), water sorption (1, 7, 14, and 28 days), contact angle, and surface roughness.
