Purpose: Iatrogenic perforation has been known as one of the most important factors in endodontic failure. Nowadays, the immediate restorative material is considered as the key of long term success. The purpose of this study was to compare the sealing ability of Amalgam, MTA, Geristore which place in furcation perforation.

Methods & Materials: In this experimental study, Fifty-five extracted human molar teeth were allocated randomly to three groups (n=15). Furcal perforations were made in teeth using an ISO 012 round bur in a slow – speed handpiece. Three different dental materials including Amalgam (group 1), MTA (group 2), Geristore (group 3) were used to repair the perforation areas. The microleakage at the repaired sites was then tested by dye penetration and cleaning method and evaluated under stereomicroscope at x20 magnification. The all data were statistically analyzed with ANOVA & Mann – Whiteny tests.

Results: The findings have shown that the perforation repaired with MTA and Geristore leaked significantly less to the tracer dye than those repaired with Amalgam (P=0.000), however, there was no statistical difference between MTA and Geristore (P=1.000).

Conclusion: The results of this study support usage of Geristore and MTA with high seal ability for perforation repair.
