Assessment of Interfacial Adaptation of New Endodontic Sealers to Root Canal Dentin with and Without a Main Guttaperch Cone: An SEM Analysis
Aim of the study: The aim of this study was to evaluate the interfacial adaptation of EndoSequence BC sealer, MTA Fillapex and Vioseal sealers to root canal Dentin with and without a main gutta-percha cone.
Material and Methods: Total of 60 single-rooted human teeth with single canal were selected and the crowns were removed at the CEJ level to standardize the root length (16 mm). Samples were instrumented using Protaper next NiTi rotary system up to size X5. After irrigation and smear layer removal samples were randomly divided according to the sealer used into three groups of 20 samples each, and each group was further subdivided based on obturation technique into six subgroup three group with cone and three group without cone of 10 sample each. Samples were stored for 48 hours before testing. Horizontal sections were obtained for all samples to evaluate the adaptation of sealer using Scanning electron microscope. The data were analyzed statistically by one-way Anova and Tukay’s post-hoc test.
Result: Vioseal showed significantly least gap and better adaptation (P<0.05) followed by MTA Fillapex then EndoSequence BC when obturated with cone were as EndoSequence BC show the least gap and better adaptation followed by Vioseal then MTA Fillapex when obturated without cone. The coronal level of all group had significantly more gaps compared to middle and apical third.
Conclusion: All the three sealers showed different grades gap width along the whole length of root canal wall.
