Abstract 

Aim

The objective of this in vitro was to assess the sealing ability of MTA, Geristore®, and amalgam with and without Bioglass as a matrix used to repair furcation perforations in mandibular molars by using dye penetration.

Materials and methods

One hundred mandibular molars were randomly divided into six experimental groups. Five teeth with perforation were used as positive control while five teeth without perforation were used as negative control group. Furcal perforations were made in the teeth. Perforations were repaired with amalgam in group 1, amalgam and Bioglass in group 2, MTA in group 3, MTA and Bioglass in group 4, Geristore® in group 5, and Geristore® and Bioglass in group 6. All repairing materials were allowed to set for 72h. Leakage at the repaired sites was then evaluated using dye penetration and clearing technique under stereomicroscope.

Results

The perforations repaired with MTA and Geristore® leaked significantly less than amalgam (p=0.000). Bioglass reduced sealing ability of MTA and Geristore® significantly (p=0.000, p=0.019), while reduced the sealing ability of amalgam insignificantly (p=0.78).

Conclusion

MTA and Geristore® have shown acceptable sealing ability in furcal perforation in comparison to amalgam while Bioglass as a matrix beneath them has reduced their sealing ability.
