In vitro study to compare the coronal microleakage of Tempit UltraF, Tempit, IRM, and Cavit by using the fluid transport model.

An adequate coronal seal is critical for the success of root canal therapy. The purpose of this study was to assess and compare the coronal microleakage of 4 temporary filling materials used to seal the access cavity in root canal treated teeth. Standardized access cavities were prepared in 55 extracted human, single canal teeth.
