“Evaluation of quality of apical seal in Resilon/Epiphany SE, gutta-percha/AH Plus and gutta-percha / tubli-seal EWT - filled by dye leakage approach - An in vitro study”

Abstract

The purpose of this study is to evaluate the apical sealing ability of resilon and epiphany SE root canal sealer when compared with gutta-percha/AH Plus sealer and gutta-percha/tubli-seal EWT sealer using cold lateral condensation obturation technique using dye leakage approach. Sixty four human maxillary permanent central incisors were used with uniform root segment of 16mm. Samples were randomly divided into three experimental groups of 20 teeth each obturated by different combination of obturating materials and four teeth were prepared as controls. Teeth were obturated in group I-with resilon/epiphany SE sealer; in group II-with gutta-percha/AH plus sealer and in group III-with gutta-percha/tubli-seal EWT sealer. Stereomicroscopic evaluation showed mean value dye penetration for group I-2.350 ± 1.148mm, for group II-2.850 ± 0.961mm, and for group III- 4.150 ± 1.226mm. Resilon/Epiphany SE group had the least penetrtion followed by gutta-percha/AH Plus and maximum in guttapercha/ tubli-seal EWT
