It is an "in vitro" study to evaluate the sealing ability of 3 root canal sealers using a dye leakage/clearing method. 40 lower incisors were instrumented by the step-back technique and divided into 4 groups. The teeth were filled with lateral condensation of guta-percha varying the root canal sealer. Fill Canal, Sealer 26, N-Rickert were tested and compared to the control group in which guttapercha cones with no seater were used. Linear dye penetration was measured after demineralizatÎon and clearing. Statistical analysÏs showed significant differences among the groups. The lowest leakage values were found in the Fill Canal group followed by the N-Rickert and the Sealer 26 groups.
