The root canal filling is one of the most important factors for a successful endodontic treatment. The aim of this study was to evaluate the root canal sealer role in the clinic and radiographic success of teeth who received endodontic treatment.  Fifty-five root canals were evaluated after endodontic treatment in the Endodontic Clinic of School Dentistry of Araraquara. There were 2 groups, according to the root canal sealer: zinc oxide and eugenol root canal sealer (Endofill) and calcium hydroxide root canal sealer (Sealapex). The results showed that 32 of 34 teeth treated with Sealapex showed clinic and radiographic success. When the sealer used was Endofill, 3 of 19 evaluated failed; a worst result than that observed in the cases filled with Sealapex. We could conclude that respecting the differences in the sample, the sealer Sealapex allows a high level of clinic and radiographic success.
