A comparative evaluation of sealing ability of restorative materials used for coronal sealing after root canal therapy.
In the past few years the importance of coronal seal following root canal therapy has been emphasised. Adhesive restorative materials have been used, considering their good bond strength and their sealing ability. In this study, the sealing ability of resin modified glass ionomer has been compared with composite resin used with fifth generation bonding agent (in vitro), using methylene blue dye penetration method. Resin modified glass ionomer showed greater leakage than composite resin, although it was not statistically significant. Further studies are needed to asses the sealing efficacy in clinical situations.
