Abstract

Purpose: Evaluation of the sealing ability of MTA (ENDOCEM Zr) and BiodentineTM in repairing the primary molar furcation perforation by using push-out bond strength test and leakage test with dye material.
Materials and Methods: Furcation perforations were made in 60 primary molars. Molars were divided randomly on the basis of the repair material used. Thirty molars were repaired by MTA (ENDOCEM Zr) and the other thirty molars were repaired by BiodentineTM. Push out bond strength test was measured and analyzed for fifteen molars of each material by using universal testing machine (Model LRX- plus, Lloyd instruments Ltd., fareham, UK). Leakage test with dye penetration was performed for fifteen molars for each material by using USB digital microscope. The images were captured and transferred to a computer equipped with the image analysis software programed. The data were statistically analyzed using Student t- test.
Results: Although MTA (ENDOCEM Zr) recorded higher push- out bond strength mean value (4.759± 1.84 MPa) than BiodentineTM (3.449± 1.30 MPa) but it was statistically non- significant (t= 0.89, P= 0.4096≥ 0.05). while BiodentineTM recorded, slight higher leakage mean value (0.951433± 0.38mm) than MTA (ENDOCEM Zr) (0.946229± 0.29mm) it was also statistically non- significant (t= 0.02, P= 0.9835≤0.05).
Conclusion: MTA (ENDOCEM Zr) and BiodentineTM showed comparable seal for furcation perforation of primary molars.
