Dissolution of a mineral trioxide aggregate sealer in endodontic solvents compared to conventional sealers
Abstract The aim of this study is to evaluate the solubility of a Mineral Trioxide Aggregate sealer (MTA-Fillapex) compared with five other sealers, calcium hydroxide (Sealapex), resin (Realseal), zinc oxide-eugenol (Tubli-Seal), and two epoxy resins (AH-26 and AH-Plus), in chloroform and eucalyptoi...

In conclusion, MTA-Fillapex was not sufficiently dissolved in either solvent. Ultrasonic activation had limited effectiveness on MTA-Fillapex dissolution, whereas it significantly increased the efficiency of solvents in dissolving a number of endodontic sealers.http://www.scielo.br/scielo.php?script=sci_arttext&pid=S1806-83242016000100215&lng=en&tlng=enEndodonticsRoot Canal Filling MaterialsSolubilitySolvents |
