| Research Abstract |
The mineralization accelerating adhesion materials that added EVA+C (RMSB) were produced experimentally, and we studied the bond strength and biocompatibility. Bond strength decreased with increase of the EVA+C addition ratio. The RMSB group showed a tendency to growth similar to Control at the early phase, and cell count was higher than an SB (Superbond) at high ratio of EVA+C group. SBP30 and 7P (SB/EVA+C=40wt%/60wt%) showed a high bond strength and a good cell proliferation. Invivo, 7P had weaker inflammation than an SB and mineralized tissue formation was good. High adhesive property and biocompatibility was oftained by RMSB-7P.
