Conclusion
MTA and 4-META/MMA-TBB resin had a higher pro-angiogenic effect while Super EBA had a less pro-angiogenic effect. CS-BG-multi had low toxicity on tube formation of HUVEC.
Methods
Mineral trioxide aggregate (MTA), 4-methacryloxyethyl trimellitate anhydride/methyl methacrylate-tri-n-butyl borane (4-META/MMA-TBB) resin, Super EBA, and CS-BG-multi, bioactive glass-related materials, were used. After curing, each material was soaked in a medium for 1 or 7 days, and then cultured for 1-7 days to investigate the effects on human umbilical vein endothelial cell (HUVEC) proliferation, angiogenesis, and vascular endothelial growth factor receptors (VEGFRs) mRNA expression.
Purpose
Regarding root-end filling materials in apical surgery, sealing ability and biocompatibility are useful for treatment. Angiogenesis, which occurs in the process of periapical wound healing, is closely related to bone formation. In this study, we investigated the effects of root-end filling materials on vascular endothelial cell proliferation and angiogenesis. Materials and
Results
In the 1-day soaked sample, there was significantly less proliferation in MTA and Super EBA on day 7 of culture. In the 7-day soaked sample, there was significantly less proliferation in Super EBA and CS-BG-multi on day 7 of culture. Tube formation was significantly high in MTA in both the 1-day and 7-day soaked samples, significantly high in SB in the 1-day soaked sample, and significantly low in Super EBA in both the 1-day and 7-day soaked samples. CS-BG-multi was comparable to the control. VEGFR-1 and VEGFR-2 mRNA expressions showed an upward trend in MTA, and a trend similar to the control in SB.
