ABSTRACT
Aim: The aim of this study was to evaluate the effect of Morinda citrifolia juice (MCJ) and Triphala on sealer penetration depth into the dentinal tubules as root canal irrigants. Materials and Methods: Forty five single rooted extracted human teeth were collected; decoronated and root canal length were standardized to16mm. Cleaning and shaping was done with protaper universal rotary instruments till F5. 30 samples were selected randomly and divided into two groups with 15 samples in each, according to the final irrigation regimen. In Group I, 5 ml of MCJ was used for 1min and in Group II; 5 ml of Triphala was used. The remaining 15 samples were irrigated with 5ml of Smear clear which acted as a positive control Group. Obturation was done with corresponding gutta-percha points and AH 26 sealer (Dentsply; DeTrey, Konstanz, Germany) labelled with fluorescent dye and left to set for 48 hrs. Then, the roots were sectioned and subjected to confocal laser microscope. Results: Statistical analysis was done by two-way analysis of variance (ANOVA) and Tukey multiple post-hoc procedures. The sealer penetration depth is higher in the MCJ group than the Triphala group at all three levels. Conclusion: MCJ showed a significant sealer penetration depth than Triphala.
