A influência de diferentes cimentos de obturação de canal na infiltração apical

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 step-back technique and divided into 4 groups. The teeth filled with lateral condensation guta-percha varying sealer. Fill Canal, Sealer 26, N-Rickert tested compared control group in which guttapercha cones no seater used. Linear penetration was measured after demineralizatÎon clearing. Statistical analysÏs showed significant differences among lowest leakage values found Canal followed 26
