To Compare and Determine the Presence of Voids in Calcium Hydroxide, Epoxy Resin, and Tricalcium Silicate when Used as a Sealer in Single Cone Obturation Technique- An in Vitro Study

Aim: The purpose of this study was to evaluate and compare the area of voids in calcium hydroxide, epoxyresin and tricalcium silicate-based sealers when employed with single cone obturation technique.

Materials and Method: Fifteen extracted single-ischolar_mained mandibular premolar teeth were cleaned and shaped and divided into three groups according to the three different sealers used. Single cone obturation was done using gutta-percha and three sealers: Sealapex, AH Plus, and Bioischolar_main RCS sealers, respectively. These teeth were decoronated at the cementoenamel junction and the ischolar_mains were sectioned at apical, middle, and coronal third, and a stereomicroscope was used to assess the area of sealer voids and digital images were taken and was analyzed by image J software. The results were statistically analyzed using SPSS software and Kruskal– Wallis and Mann–Whitney tests.

Results: All three groups showed voids in all the sections. Significant differences were found between these sealers regarding their section wise area of voids (P < 0.05). Similarly, there were significant differences in their overall area of voids (P < 0.05) with AH Plus showing significantly least area of voids followed by Sealapex.

Conclusion: Single cone obturation with AH Plus showed least mean area of voids, whereas Single cone obturation with BioRooot RCS had significantly the most mean area of voids.
