Characterization of Phosphopullulan (PPL)-containing MTA sealer (a–d). Cross section observation of typical dye leakage after root canal treatment with different endodontic sealer. Phosphopullulan (PPL) -containing MTA sealer, resin-based sealer (AH Plus), MTA-containing resin-based sealer (Fillapex), and Zinc oxide non-eugenol sealer (Canals N). Dye leakage (%) of different endodontic sealers with different dentin treatments (paper-point, dry, and wet treatments denoted by a black circle, triangle, and square, respectively). Leakage test revealed that MTA cement with 10% phosphopullulan bonded to dried, paper point dried, and wet dentin surfaces completely prevented interfacial dye infiltration (p < 0.01), whereas the MTA cement without phosphopullulan could not prevent die infiltration at all. (e) Calcium release of different endodontic sealers. f. Apatite precipitation on different endodontic sealer surface in simulated body fluids. g. pH measurement of different endodontic sealers. h. Cell viability of different endodontic sealers. PPL containing MTA sealer (100%) revealed significantly higher cell viability than compared to the other three commercial sealers (p < 0.01).
