Aim To evaluate the long‐term sealing ability of four contemporary endodontic sealers [Pulp Canal Sealer (PCS), AH‐Plus, GuttaFlow and Epiphany] using a fluid filtration technique. Methodology The palatal roots of 40 human maxillary molar teeth were selected and the root canal was prepared using a crown‐down technique (apical size 40, 6% taper). Roots were irrigated with 3% NaOCl, 17% EDTA solution and rinsed with distilled water. Canals were filled with either PCS, AH‐Plus, GuttaFlow or Epiphany using a single‐cone technique ( n = 8). Twenty‐four hours after filling, the roots were connected to an automatic flow‐recording device (Flodec ® System) filled with double‐distilled water under pressure (0.2 bar) to measure leakage. Flow rates were assessed at 6, 12 or 24‐h and after 1‐year of storage. Results None of the materials fully prevented fluid flow. Fluid flow decreased after 6 h and decreased further after 12 h. After 24 h, PCS and AH‐Plus allowed significantly more fluid flow than GuttaFlow and Epiphany. After 1 year, PCS allowed significantly more fluid flow than the other materials. No significant changes in leakage occurred between 24 h and 1 year. Conclusions GuttaFlow and Epiphany allowed less fluid movement along filled straight roots.
