Root canal aberrations created during preparation were determined by the use of double exposure radiographic technique. The prepared canals were filled with lateral condensation of gutta\u2010percha and one or other of two root canal sealers (Pulp Canal Sealer and Sealapex). Leakage along the apical 10\u2003mm of roots was measured with a fluid transport model at 1, 3, 6, 9 and 12\u2010month intervals.<\/jats:p><jats:p><jats:bold>Results\u2002<\/jats:bold>There were no statistically significant differences between straight and curved root canals (<jats:italic>P<\/jats:italic>\u2003&gt;\u20030.05) for prevalence of root canal transportation. The prevalence of apical transportation was 80% in the straight and 85% in the curved root canals. A complete seal was more frequently observed in straight canals compared with curved canals.
