“…Although there was no adhesion between the Tefion-base material and tooth strueture, the material virtually prevented any dye from entering the eanal. The microleakage observed in the eontrol teeth was eonsistent with other research using methylene blue dye (19). The size of the Poly R molecule was reported to be larger than methylene blue molecule but smaller than bacteria (20).…”

Root canals in extracted maxillary anterior teeth were filled with an experimental Teflon®‐base material and then stored in a dye solution. Penetration of the dye into the canal space was measured and compared with the penetration of dye in control teeth that were filled with laterally condensed gutta‐percha and a sealer. The sealing ability of the experimental material was found to be statistically significantly better than that of the control.

“…Up to date doctrine of endodontic treatment is based on biomechanical canal instrumentation and irrigation [1]. The idea about optimal apical hermetic sealing with biologic properties forced many investigators to find ideal obturation material that could also prevent overfilling [2,3]. This material needed to be biocompatible, adhesive and physico-chemically stable to perform obturation [4,5].…”

Summary Introduction Prognosis of endodontically treated tooth is directly correlated to the quality of apical obturation. Modern concept of endodontics in particular way points out the quality of apical filling. The aim of this study was to assess the quality of root canal obturation with MTA apical plug using the method of gas (argon) penetration. Material and Methods Sixty-six freshly extracted single rooted (single canal) teeth were divided into the two experimental (30 teeth) and one control group (6). All canals were instrumented using hand and rotary files in step-back technique and copious irrigation of 1%NaOCl. In the first experimental group teeth were obturated using different sealers: Gutta Flow (Roeko), AH Plus (DeTrey), Acroseal (Septodont) and mono gutta-percha cone (10 canals each). In the second experimental group obturation involved 3 mm of MTA-Angelus apical plug while the remaining canal space was filled with the same three sealers as in the first group. The rate of gas permeability by Leak detector-Edwards LD 416 was measured in all teeth. Results The best seal was found in teeth obturated with Gutta Flow and MTA plug with average diffusion rate of 264.4 sec while the worst quality of obturation was found with Acroseal (178.5 sec-the highest gas permeability). All samples with MTA plug exhibited significantly lower leakage than the samples filled without MTA apical plug. Conclusion Root canals filled with MTA apical plug exhibited statistically significant lower gas permeability in comparison to the ones filled with sealer and guttapercha cones only.
