Comparative evaluation of the apical seal of Resilon tm with sealer, Guttapercha with resin sealer and Guttapercha with Zinc oxide eugenol sealer in permanent single rooted teeth– an in vitro study

Objective: The era of endodontics has taken a new dimension with the advent of a synthetic, thermoplastic resin filling material, named Resilon. Our in vitro study tested the efficacy of this new obturating system, versus the ageold material Guttapercha. Materials & Methods: Forty five central incisor teeth, extracted due to periodontal reasons, were assigned to two experimental (Resilon and AH 26) and one control group. They were obturated by lateral condensation method, immersed in 2% methylene blue solution, sectioned longitudinally and examined under stereomicroscope. Dye penetration was recorded as an indicator of microleakage. Analysis of variance (One Way ANOVA) and post hoc multiple comparisons were used for statistical analyses. Results: Analysis of variance (One Way ANOVA) showed highly significant (P<0.001) Health Sciences 2014;1(3):JS001F 1 An Open Access Peer Reviewed E-Journal Original ResearchComparative evaluation of the apical seal of Resilon tm with sealer, Guttapercha with resin sealer and Guttapercha with Zinc oxide eugenol sealer in permanent single rooted teeth– an in vitro study difference among the groups tested. Post hoc multiple comparisons revealed the difference between groups, of which dye penetration in Resilon and AH 26 was significantly different from control and between themselves. Conclusion : Resilon has better sealing ability when compared to the other two filling materials .
