Abstract

Abstract: Objective: To compare the apical sealing ability of iRoot SP bioceramic root-filling sealers with that of iRoot BP Plus root-end filling materials. Methods: A total of 102 mandibular premolar teeth were extracted and assigned to five groups: Group A: AH Plus using the warm gutta-percha vertical condensation (WGPVC) technique; Group B: iRoot SP sealer-only; Group C: iRoot SP sealer using the single-cone obturation technique (SCO); Group D: iRoot SP using SCO plus iRoot BP Plus as the root-end filling material; and Group E: iRoot SP+ SCO+ mineral trioxide aggregate (MTA) as the root-end filling material. Dye penetration experiments were performed using the ink, and the longest length of microleakage was detected with stereoscopic microscope and scanning electron microscope. Results: The mean values of microleakage in Groups A, B, C, D, and E were (0.65 ±0.73) mm , (0.33±0.35) mm, (0.32±0.20) mm, (0.24±0.32) mm, and (0.23±0.31) mm, respectively. In the iRoot SP sealer-only group, microleakage occurred mainly in the fissures or bubbles within the sealer, and in the iRoot BP Plus and MTA root-end filling groups, microleakage occurred mainly in the area between the canal wall and material. Conclusion: The apical sealing ability of iRoot SP was similar to that of iRoot BP Plus.

Key words: iRoot BP Plus, iRoot SP, retrograde obturation, apical microleakage, apical seal
