Vasiliadis L, Kodonas K, Economides N, Gogos C, Stavrianos C. Short‐ and long‐term sealing ability of Gutta‐flow and AH‐Plus using an ex vivo fluid transport model. International Endodontic Journal , 43 , 377–381, 2010. Abstract Aim To use the fluid transport model to evaluate the ex vivo short‐ and long‐term microleakage along root canals filled with Gutta‐flow or AH‐Plus using the cold lateral compaction technique. Methodology A total of 38 single‐rooted human teeth were used for the assessment of microleakage. The crowns of the teeth were sectioned below their cemento–enamel junctions to adjust the length of the roots to approximately 15 mm. The root canals were instrumented using the step‐back technique and filled using cold lateral condensation. The sealer employed was either Gutta‐flow (Group A) or AH‐Plus (Group B). Microleakage along the root canals was evaluated using a fluid transport model after periods of 1 week and 3 months. Results The microleakage values (μL h −1 ) for group A were 0.36 ± 0.33 at 1 week and 0.41 ± 0.36 at 3 months. Group B showed mean microleakage values 0.2 ± 0.31 at 1 week and 0.28 ± 0.38 at 3 months. Statistical analysis indicated no significant differences ( P > 0.05) between the two groups after either 1 week or 3 months. Conclusions There was no significant difference between AH‐plus and Gutta‐flow in terms of sealing ability.
