摘要

Background

This study aims to investigate the effects of using EDTA, phytic acid (IP6), chitosan, and proanthocyanidin (PAs) as final irrigation solutions on the push-out bond strength (PBS) of root canal filling.

Materials methods

In the present study, 56 extracted human incisors were utilized. All teeth were decoronated at the cementoenamel junction. Following the root canal chemomechanical preparation, the teeth were randomly divided into 7 groups according to the final irrigation procedures: Group 1: Control, Group 2: EDTA, Group 3: IP6, Group 4: Chitosan, Group 5: EDTA + PAs, Group 6: IP6 + PAs, Group 7: Chitosan + PAs. The root canals were filled using the cold lateral condensation technique with gutta-percha and resin-based root canal sealer. Samples were obtained horizontally cut from the apical third of the teeth and subjected to push-out bond strength (PBS) using a universal testing machine. Data was statistically analyzed using one-way ANOVA and post hoc Tukey HSD test (α = 0.05).

Results

The highest value was obtained in Group 6 (12.14 ± 0.47 MPa), and the lowest value in Group 1 (5.80 ± 0,44 MPa) (P < 0.05). Group 6 has shown a higher PBS value than Group 5 (11.72 ± 0.14 MPa) and Group 7 (11.94 ± 0.42 MPa) (P > 0.05). There were statistically significant differences between all other groups, except Groups 3 and 4 (P < 0.05). The failure type was mostly adhesive, and no cohesive failures were observed.

Conclusion

The use of EDTA, IP6, and chitosan for final irrigation has enhanced the bond strength values of resin-based root canal sealer to dentin. Furthermore, the use of PAs after EDTA, IP6, and chitosan increased the bond strength values more than when these solutions were used alone.
