Abstract
Objective: The objective was to compare the sealing ability of two root canal sealers viz.: Hybrid Root SEAL (Sun Medical, Tokyo, Japan) and iRoot SP (Innovative BioCeramix Inc., Vancouver, Canada). Materials and Methods: A sample of 60 permanent single rooted, human maxillary central incisors of similar sizes was selected for the study. The teeth were decoronated and randomly divided into two groups viz.: Group A and Group B, comprising of thirty teeth each. In Group A, Hybrid Root SEAL and Group B, iRoot SP were used as root canal sealers along with Gutta-percha cones using lateral condensation technique to obturate the canals. After obturation roots were covered with nail paint except 2.0 mm of root and stored in 0.5% methylene blue dye for 1 week. The teeth were immersed in 10 ml of 65% nitric acid for complete dissolution and subsequently subjected to UV spectrophotometer to quantify the concentration of the dye in each sample. The data were analyzed using the unpaired t-test. Results: The mean dye leakage value in Group B (0.368) was less as compared to Group A (0.408). However, statistically the difference was nonsignificant (P = 0.053). Conclusion: There was no statistically significant difference among the two groups.
