Aim: Aim of the present study was to evaluate the apical leakage in gutta-percha/AH plus and resilon/epiphany filled root canals using two dye penetration techniques. Materials and methods: Sixty freshly extracted human single-rooted teeth were collected. The crown portion of each tooth was sectioned from the cementoenamel junction using a diamond disk. The canals were instrumented using Step back technique up to a caliber of 40. The roots were randomly divided into four experimental groups of 15 sample units each. All the groups are obturated using lateral compaction technique. Samples were placed in India ink and stored in an incubator for 7 days after which they were thoroughly washed under tap water and dried. The roots were divided into longitudinal splitting technique with diamond disks and using clearing technique was checked for linear dye penetration using stereomicroscope. The surfaces were scanned and surfaces with greatest dye penetration were measured by using De winter Biowizard software system. Results: The mean leakage for groups I, II, III, and IV are 2.31980, 2.68140, 4.11567, and 4.21047 respectively. One-way ANOVA was applied to the mean leakage scores of different groups, found a significant difference between mean leakage scores. F value of 3.266 and it was found to be significant with a p value of 0.028. Significant differences were obtained for mean comparisons of groups I and III, groups I and IV and groups III and IV. Further, between groups I and II, groups II and III, and groups III and IV no significant differences were observed. Conclusion: In conclusion, gutta-percha/AH Plus sealed root canals showed lesser leakage than the Resilon Epiphany groups and there was no significant difference in the two different methodologies used for dye penetration. Clinical significance: Tightly adapted endodontic filling material is one of the goals in successful clinical endodontics and Improvements in the adhesive technology have fostered attempts to reduce apical and coronal leakage by bonding to the root canal walls to obtain a solid monoblock.
