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.
