Abstract

Objective: BioRoot, which contains pure calcium silicate, is used in cold lateral compaction. However, hydroxyl ions are still released when BioRoot is used in warm vertical compaction. This study compared the effects of cold and warm vertical compaction obturation on the push-out bond strength of BioRoot. Methods: Specimens from 16 root canals instrumented with ProTaper Next X5 50/06 were divided into two groups (n=16 specimens per group). Group 1 was obturated using cold lateral compaction, whereas Group 2 was obturated using warm vertical compaction. All samples were incubated for 48 h (37°C, 100% humidity) and embedded into an acrylic block. Starting at 7 mm from the apex, two 2-mm-thick slices of each sample were cut. Dislodgement resistance was measured using a universal testing machine, and the push-out bond strength was calculated. Results: There was a significant difference in the push-out bond strength value between cold (4.5–41.1 MPa) and warm (4.12–24.25 MPa) compaction obturation (p<0.05). Conclusion: Cold lateral compaction provides better adhesion capability than warm vertical compaction in root canal obturation.
