An in vitro comparison between the apical sealing abilities of resilon with Epiphany sealer and gutta-percha with AH plus sealer.

Context: The study assesses the apical sealing ability of two obturating materials (resilon and gutta-percha) with their sealants by means of the dye penetration method using India ink.

Aims: To compare the resistance to apical dye penetration between resilon (with Epiphany sealer; Epiphany, Pentron clinical technologies, USA) and gutta-percha (with AH Plus sealer; Dentsply, Maillefer, Germany). It was hypothesized that there would be no difference between the two groups with regard to apical dye penetration.
