ResumoNinety extracted human teeth with a single canal and a large patent foramen were obturated by one of three methods after placement of a master gutta-percha cone and sealer. The apical seals were evaluated by ink penetration. Statistical analysis of the results indicated that the group obturated with the high-temperature injected thermoplasticized technique (Obtura) had an apical seal comparable to the group obturated by lateral condensation. The group obturated with the low-temperature injected thermoplasticized technique (Ultrafil) produced an apical seal significantly better than the other two techniques.
