Aim of the Study: The aim of the present study was to compare the dislodgement resistance of Biodentine, EndoSequence Root Repair Material putty and Tech Biosealer Apex as root repair materials in the presence or absence of an acidic environment could affect a compromised bond to dentin.
Material and Methods: One hundred eighty root sections were instrumented. The specimens were randomly divided into 3 groups (n = 60) and repair materials were fitted incrementally into the canal spaces. The specimens were placed in an incubator for allowed to set and then divided randomly into 4 subgroups (n = 15). The specimens were wrapped in pieces of gauze soaked in phosphate buffer saline solution (pH = 7.4) and butyric acid buffered at pH values of 6.4, 5.4, and 4.4. Push-out bond strength values were measured using a universal testing machine. The slices was examined under the a stereomicroscope for evaluating to failure modes.
Results: The push-out bond values of pH 7.4 was higher than pH 4.4 in all the test materials. While the push-out bond strength values of Biodentine was significantly higher than Tech Biosealer in all pH values, there was no statistically significant difference between Biodentine and Endosequence Putty groups (P > 0.05). Inspection of the samples showed adhesive failure mode was the most frequently observed type in all groups.
Conclusion: Physical and chemical properties of the root repair materials, based calcium silicate, may affect in acidic pH. A low pH value facilitates leakage and dislocation of repair materials under mechanical loads.
