RESILON - “ENDOBONDICS”

To evaluate and compare the new Resilon obturation material with Gutta percha for Fracture Resistance,Marginal gap and Solubility. Fracture resistance: Forty extracted human teeth were sectioned at the cementoenamel junction, biomechanical preparation carried out and they were obturated as follows: G1 = Lateral condensation of Gutta-percha with AH plus sealer. G2 = Vertical condensation of Guttapercha with AH plus sealer. G3 = Lateral condensation of Resilon with epiphany sealer. G4 = Verticalcondensation of Resilon with epiphany sealer.After obturation, the teeth were tested under the universal testing machine. Teeth obturated with Gutta percha and Resilon were sectioned and evaluated under Scanning Electron Microscope (SEM) to study gap formation. Solubility of Resilon with various solvents was evaluated compared to Gutta percha. Better fracture resistance and absence of gap between tooth wall and resilon material was found in contrast to gutta percha. It was also found that resilon was soluble in organic solvents like chloroform and xylol only
