In vitro comparison of coronal microleakage between Resilon alone and gutta-percha with a glass-ionomer intraorifice barrier using a fluid filtration model.

The prevention and control of coronal microleakage is critical for successful endodontic outcomes. The purpose of this study was to compare coronal microleakage between Resilon alone and gutta-percha with a glass ionomer intraorifice barrier using a fluid filtration model. Thirty-four extracted human teeth were decoronated, prepared to a standardized length of 16 mm, and instrumented to a .
