Abstract

Abstract: Objective: To study the effect of iRoot SP and AH Plus on the bonding strength of root inner canal wall. Methods: Sixty single tube teeth were collected and randomly divided into iRoot SP and AH plus (n=30). Each group was randomly divided into 3 subgroups and filled by warm vertical technique, the single cone technique, and lateral condensation technique. After 1 week, all samples were cut into slices with 1 mm in thickness. The strength was calculated by universal test machine, and the fracture mode and the percentage were calculated. Results: iRoot SP and AH plus were similar and the difference was not significant (P>0.05). The highest value (8.38±3.91) MPa was in the apical region of iRoot SP (P<0.05). The proportion of fracture mode in each group was: mixed failure>cohesin failure>adhesion failure. Conclusion: iRoot SP can be similar or even better than AH plus, and the apical region has the highest bonding strength by the single cone method. The fracture mode is dominated by mixed failure.

Key words: iRoot SP, AH Plus, bond strength, filling technology
