ABSTRACT

Context: Root canal sealers are principally used to fill the irregularities of the root canal system or to attach the gutta-percha to the root canal walls. Endodontic sealers are used in the obturation of root canal systems to achieve a fluid-tight seal throughout the canal including the apical foramen and canal irregularities and minor discrepancies between the dentinal wall of the root canal and the core filling material. Aim: To evaluate the sealing ability of four different root canal sealers using a stereomicroscope using lateral condensation obturation technique. Methodology: 40 single rooted teeth with mature apices were used for this study. Samples were randomly divided into 4 groups. The samples were prepared and obturated using gutta percha and sealer with lateral condensation technique. Group 1 samples were obturated using AH Plus sealer, group 2 with Bio C sealer, group 3 with MTA fillapex and group 4 with Sealapex. The samples were sectioned longitudinally and were studied under a stereomicroscope of 5X magnification. Statistical Analysis: One way ANOVA test followed by Tukeys post hoc analysis was used to compare the Mean Dye Penetration depth (in mm) between four groups. Results: Significant difference was seen between the sealing ability of AH Plus, Bio C sealer, MTA Fillapex and Sealapex. AH Plus sealer showed better results compared to the other sealers.
