The aim of this paper was to evaluate a possible correlation between obturation limits and leakage. Thirty-six extracted human mandibular incisors were used, characterized by straight and single canals, non-anatomical complexities, absence of previous endodontic treatment, complete root formation and patent foramen. For standardization of the specimens for the leakage analysis, foraminal instru...

The purpose of this study was to assess the efficacy of the thermoplastic filling techniques, Touch'n Heat®, TC® System and Tagger's Hybrid Technique, in oval-shaped canals at the apical third.Thirty-three human uniradicular lower pre-molar teeth were treated by the reciprocating movement technique and were subsequently split into 3 groups, according to the filling technique performed:Touch'n H...
