摘要: Objective The present study systematically compared the sealing ability of oval-shaped canals filled using System B heat source with either gutta-percha/sealer or Resilon/Epiphany. Study design Eighty mandibular incisors were selected after buccolingual and mesiodistal radiographs divided into 3 experimental groups (n = 20). teeth obturated as follows: G1: gutta-percha/Pulp Canal Sealer EWT cold lateral condensation; G2: source; G3: Resilon tips Epiphany sealer source. roots mounted in a bacterial leakage model system was checked daily during following 9 weeks. log rank test used to analyze data at intervals 3, 6, level significance set P Results Seven samples G1 (35%) 5 (20%) each G2 G3 fully contaminated Data showed no significant difference between traditional Resilon/Epiphany ( > .05). However, both materials condensation when Conclusions results demonstrated that combination do not improve resistance fillings.
