Objectives: To asses the biocompatibility and biomechanical properties of an experimental bis-phenol-A and bis-GMA free E-glass fiber-reinforced composites (FRCs) with hexanediol dimethacrylate (HDDMA)-based resin. Methods: 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. The data were analyzed statistically by ANOVA (p<0>0.05). The exp-1 showed comparable contact angle with the control groups. Conclusion: The experimental HDDMA/TEGDMA FRCs might be potential alternatives for bis-GMA-based FRCs, with their superior cytocompatibility and comparable biomechanical properties. Clinical Significance: The excellent biocompatibility of HDDMA/TEGDMA resin can be employed in a novel FRC which has acceptable biocompatibility and comparable mechanical properties for dentistry. Moreover, the novel FRC lacks the shortcomings related to bis-GMA based resins. |
