The purpose of this study was to evaluate and compare the area of voids in calcium hydroxide, epoxy-resin and tricalcium silicate-based sealers when employed with single cone obturation technique.
Fifteen extracted single-rooted 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 Bioroot RCS sealers, respectively. These teeth were decoronated at the cementoenamel junction and the roots 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.
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.
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.
