BACKGROUND Obturation voids have a potential to allow leakage through the sealer mass. Single cone obturation technique is more prone to have voids, as the volume of sealer used is larger as compared to other techniques. Aim-To compare the area of voids in Endoseal MTA, pulpdent and AH Plus sealers when employed with SC obturation technique. MATERIALS AND METHODS This is a randomised controlled study. Forty-five teeth were cleaned, shaped and divided into three groups for SC obturation using

... oseal MTA, AH Plus and pulpdent sealers, respectively. Teeth were sectioned at apical, middle and coronal third. Stereomicroscope, digital image and image software were used to assess the area of sealer voids. SPSS software and Kruskal-Wallis and Mann-Whitney tests were used to analyse the results. RESULTS The three tested sealers showed voids in all the sections except Endoseal, which was void free in apical and middle sections. There were significant differences between these sealers regarding their section wise area of voids (P < 0.05). Similarly, Endoseal MTA showed the least overall area of voids followed by AH Plus and there were significant differences in their overall mean area of voids (P < 0.05). CONCLUSION SC obturation with Endoseal MTA, which showed void free apical and middle-third sections had significantly least area of voids in the sealer followed by the one with AH Plus sealer, whereas pulpdent sealers showed maximum area of voids.
