Summary Successful root canal therapy is dependent upon obturating the root canal system. A critical component of the filling procedure is sealer placement. This in vitro study investigated the efficacy of six methods of sealer placement using clear plastic blocks with simulated curved canals instrumented to the apex using a stepback technique. After sealer placement and setting, the blocks were cross‐sectioned at 2 mm intervals from midcanal to apex. The sections were evaluated with a stereo operating microscope at × 6 magnification for placement of an evently distibuted layer of sealer around the prepared canal walls. The lentulo spiral and the Max‐i‐Probe Delivery System were the most effective means of sealer placement, followed by ultrasonic and sonic files. The least effective methods were the paper point and the K file.
