초록

The purpose of this study was to evaluate the marginal sealing ability of 'vivadent.' Using freshly extracted human teeth and 2% aqueous methylene blue, the marginal leakage of dye in restorative materials such as vivadent with acid etching technique, Durafill with acid etching technique, silar with acid etching technique, Adaptic, and Amalgam were investigated at 37℃ and under temperature cycling in range of 4℃-60℃. The results were as follows; 1. All filling materials showed some degree of marginal penetration by 2% methylene blue dye. 2. Vivadent with acid etching technique revealed effective marginal sealing ability, but under temperature cycling it showed increased marginal leakage. 3. All resins showed greater marginal leakage than amalgam restoration. 4. Vivadent had the most effective marginal sealing ability in experimented resins.
