Influence of different irrigation solutions on bond strength of MTA Fillapex root canal sealer

26238

OBJECTIVE: The purpose of this in vitro study was to evaluate the effect of different irrigation solutions on bond strength of MTA Fillapex root canal sealer by using the push-out test. MATERIALS AND METHOD: Forty extracted human permanent upper canine teeth were used. The teeth randomly divided into four groups (n=10) according to final irrigation. Group 1; 5 ml 1.3% NaOCl, Group 2; 5 ml 17% EDTA, Group 3; 5 ml 17% EDTA+5 ml 2% CHX and Group 4; 5 ml MTAD. Root canals were filled by using MTA Fillapex root canal sealer and gutta percha by means of the cold lateral condensation technique. After setting of the root canal sealer, twomillimeter thick slices were obtained from the specimens and the push-out test was performed. All data were submitted to one way ANOVA and post-hoc Tukey tests. RESULTS: The group with MTAD had significantly lowerbond strength than all of the other groups (p 0.05). No statistically significant difference was found between the other groups (p 0.05). CONCLUSION: The bond strength of MTA Fillapex was adversely influenced by MTAD. Therefore, when using MTA Fillapex as a root canal sealer, MTAD should not be preferred for irrigation of root canals.
