title: Evaluation of coronal microleakage after endodontic treatment.
abstract: A new method is suggested for placing a coronal seal in the orifice of the root canal right after root canal therapy. Root canal therapy was done on 94 extracted human maxillary centrals. Three mm of the coronal gutta-percha was replaced by either Cavit, TERM, or amalgam with cavity varnish. After thermocycling and 2 wk of immersion in dye, the amount of dye penetration was measured. The results showed that amalgam with two coats of cavity varnish sealed significantly better than Cavit and TERM. However, Cavit and TERM were still significantly better than a positive control group.
