Effectiveness of different obturation techniques in surpassing the ledge formed in simulated curved canals
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...

Introduction: The purpose of this study was to evaluate the sealing ability of 3 obturation techniques in oval-shaped canals by bacterial leakage assessment. Methods: Sixty mandibular incisors with oval canals were selected after providing buccolingual and mesiodistal radiographs. The teeth were sectioned at a 10 mm distance from the apex. After instrumentation, the teeth were divided into 3 gr...

15 صفحه اولCalcium Hydroxide Dressing Influences the Obturation of Simulated Lateral Canals.
AIM The aim of this study was to investigate the influence of calcium hydroxide dressing on the filling of simulated lateral canals by different obturation techniques. MATERIALS AND METHODS Sixty single-root-premolars were instrumented. Simulated lateral canals were drilled on each third of the roots. The teeth were divided into four groups: no dressing and obturation by lateral condensation ...
