Abstract

Introduction: Increase in pH value on external root surface following intracanal application of materials is a treatment approach for external root resorption. The goal of present in vitro study was to compare pH changes in external simulated root defects after intracanal biodentine and modified portland cement dressing(MPC) insertion. Materials &amp; Methods: In this in vitro study twenty-four bilaterally matched pairs of human teeth with single root were randomly assigned to two experimental groups (20 matched pairs of teeth for Biodentine and MPC) and control group (four matched pairs of teeth for calcium hydroxide and saline. The buccal root surface cavity preparation measuring 0.7mm depth and 1.4mm width were made and then root were prepared using Race rotary files system to apical size 40, 0.08 taper. The pH changes of the experimental and control groups were measured immediately before, after placement of materials at different intervals of 24 hours, 1, 2, 3, 4 and 8 weeks. A repeated measures analysis of variance was used for comparing changes in pH in version 22 SPSS software at the significant level of 0.05. Results: Significant pH changes occurred over time in the Biodentine and MPC groups (P<0.001). Overall, pH value was significantly higher in Biodentine compared with MPC groups (P<0.001). Conclusion: with respect to these results, study we can take advantage of MPC and Biodentine for treating external root resorption.
