AIM: To evaluate the push-out bond strength of MTA Fillapex (Angelus) and compare it with ProRoot MTA (Dentsply) and AH Plus (Dentsply). DESIGN: Thirty extracted single-rooted teeth were selected and prepared using a rotary system. The samples were divided randomly into three groups (n = 10) and obturated, respectively, with: (1) AH Plus + gutta-percha (DiaDent); (2) MTA Fillapex + gutta-percha; (3) ProRoot MTA. Each root was sectioned into 1-mm-thick slices and 30 samples for each group were obtained. The samples were subjected to push-out test. Failure modes were examined under 30× magnification. The results were analysed statistically by one-way ANOVA and Tukey's test. RESULTS: Mean push-out bond strength values were ranked as follows: ProRoot MTA > AH Plus > MTA Fillapex. Statistically significant differences were found among all groups (p < 0.05). CONCLUSION: ProRoot MTA had the highest bond strength, whilst MTA Fillapex displayed the lowest values among the groups.
