ABSTRACT:Sealer cements are an essential component of root-filling materials to fill any voids and gaps between the main root-filling material and root dentin. Good adhesion to tooth material within the root canal is one of the ideal properties of a sealer cement, which potentially influences both leakage and root strength. Increased adhesive properties to dentin may lead to greater strength of the restored tooth, which may provide greater resistance to tooth fracture and clinical longevity of an endodontically treated tooth. The present study was to compare the push-out bond strength of 3 different root canal sealers. Forty-five extracted human single-rooted teeth were selected and decoronated below the cement enamel junction so that all the roots were 12 mm in length. The working length was determined and the cervical portion of the canals was prepared by using #2 and #3 Gates-Glidden drills. The root canals were instrumented by means of the step-back technique to a size 40 K-Flexofile (Dentsply). There was a significant difference between all the 3 groups with AH plus sealer group (group A) showing stastically significantly higher bond strength at all the three levels when compared with MTA Fillapex and GuttaFlow 2 group. Significant difference was also observed between MTA Fillapex group (group B) and GuttaFlow 2 (group C) with higher bond strength values for MTA Fillapex when compared with GuttaFlow 2 which has least bond strength values. MTA Fillapex showed lower bond strength when compared to that of AH plus sealer, MTA Fillapex presented acceptable resistance to dislodgement, similar to that observed in samples filled with an epoxy-based root canal sealer and it is more biocompatible and can be recommended for use with further investigations of other features of this root canal sealer.
