AIM To compare the average sealer cement film thickness and the extent and pattern of sealer penetration into dentinal tubules in association with four obturation techniques in curved root canals. METHODOLOGY Mesial canals of 44 extracted mandibular molars were randomly divided among the SimpliFill, continuous wave, Thermafil and 0.04 matched taper (master cones) lateral compaction obturation...

Aim: To compare the effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved root canals. Methods: Eighty acrylic-resin blocks with curved canals were instrumented with Gates-Glidden drills to simulate a ledge formation. Then, a K-File #10 was used for trying to surpass the deviation, and the blocks that permitted surpassing were rejected. The remainin...

OBJECTIVES The aim of this study was to assess the apical sealing ability of different core materials used with Epiphany(TM) sealer and to evaluate the effect of Resilon/Epiphany(TM) system on creating an apical mono-block seal. METHODS Fifty-five extracted human teeth were used. Forty-five were selected and randomly divided into three groups and ten teeth were used as positive and negative c...

OBJECTIVE Aim of the present study was to evaluate the cytotoxicity of Real Seal 1 compared to other commercially available endodontic filling materials: Real Seal (SybronEndo, Orange, CA, USA) and Thermafil (Tulsa Dental, Tulsa, OK, USA). MATERIAL AND METHODS Periodontal ligament cells from healthy patients were cultured. The eluate of Real Seal 1(TM) (RS1), Real Seal (RS) and Thermafil (TF)...
