ABSTRACT
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. Settings anddesign:
Hundred mandibular first premolars from individuals aged between 20 to 25 years were selected after their lengths were standardized. Materials andMethods:
Instrumentation was performed with NiTi hand protaper files (Dentsply, Maillefer) using EDTA paste and copious irrigation with 2.5% sodium hypochlorite. Experimental group 1 consisted of roots that were treated with Epiphany primer and obturated with resilon (with Epiphany sealer). Experimental group 2 consisted of those obturated with gutta-percha using AH Plus sealer. The samples were immersed in blue India Ink and cleared using 5% nitric acid. Dye penetration was assessed under a stereomicroscope. Statisticalanalysis:
Mann-Whitney U test.Results:
Roots obturated with resilon core material and Epiphany sealer exhibited lesser mean apical dye penetration (1.281 mm; SD 0.742) in comparison to those obturated with gutta-percha and AH plus sealer (2.154 mm; SD 0.814). The difference was found to be highly significant (P<0.0025).Conclusion:
Resilon (with Epiphany sealer) provided better radicular apical sealing in comparison to gutta percha (with AH Plus sealer).
