Title

AN INVESTIGATION ON THE ADHESION OF TWO ENDODONTIC SEALERS (AH 26, DORIFILL) TO DENTIN

Pages

  53-60

Abstract

 Background and aim: TENSILE BOND STRENGTH of ENDODONTIC SEALERs to DENTIN is an indicative of sealer's adhesion to DENTIN. Due to the fact that Gutta-percha is not bonded to DENTIN walls, the adhesion of a root canal sealer to DENTIN is an important issue in endodontics. The goal of this study was to compare the TENSILE BOND STRENGTH of two sealers, AH26 and Dorifill, with DENTIN.Materials and Methods: In this experimental study, 30 extracted human first and second molars, with no occlusal carries, were stored in 0.9% Nacl. The enamel was removed 1mm below the central occlusal groove. The roots were cut at 2mm below the CEJ. Wire hooks, made of orthodontic wire (0.5mm), were fixed to DENTIN surfaces and sealers.Aluminum cylinders were used to place sealer on the DENTIN surface and stabalized with two drops of wax. Two groups of sealers (AH26, Dorifill) were placed within the cylinders (n=15). The lower end of the wire hook was lowered into the soft unset sealer. After 24 hours, wax drops were removed and each specimen was tested by zwick tester at the speed of 2mm/min. Data were subjected to Independenl samples t-test.Results: The mean TENSILE BOND STRENGTH values were 1.855±0.383Mpa for AH26and 0.135±0.04 Mpa for Dorifill attributing higher TENSILE BOND STRENGTH to AH26 than Dorifill.Conclusion: Applying AH26 in root canal therapy would be more successful than dorifill.
