Aim: The aim of the study is to evaluate the adhesiveness of the AH Plus plug cement, plus the mineral trioxide aggregate (MTA) in different proportions, through the push-out test.
Materials and methods: The authors utilized fifty premolars with a single conduit, which were divided into five groups with 10 teeth. In group 1, the authors performed an obturation with AH Plus cement, group 2 was filled with AH Plus cement with 10% of MTA, group 3 was filled with AH Plus cement plus 20% MTA, group 4 was filled with AH Plus with 30% of MTA and group 5 filling was performed with the MTA Fillapex endodontic cement. The specimens were sectioned in 2 mm slices and submitted to the push-out test in a universal testing machine. The authors cataloged the data and follow through with statistical analysis based on T-test for independent samples, with a significance level of 5%.
Results: There was no statistical difference in group 2. Groups 3 and 4 presented better adhesion than AH Plus cement and MTA Fillapex. There was no statistical difference between the AH Plus cement and the MTA Fillapex.
Conclusion: The authors concluded that the addition of MTA in the proportion of 10% to the AH Plus does not alter its adhesive property. They also observed that when the MTA increased by 20% and 30% there was an increase in the adhesiveness of the material when submitted to the push-out test.
Clinical significance: The relevance of this study refers to the MTA inducing the deposition of mineralized tissue. However, it is necessary to compare it to the AH Plus cement considered “Gold Standard” in physical-chemical properties tests.
