Abstract

Objective: The aim of this study was to evaluate coronal and apical microleakage and dentin adaptation of three different types of mineral trioxide aggregate (MTA) and Biodentine using scanning electron microscope (SEM) in single visit apexification procedures carried out in vitro.
Materials and Methods: A single visit apexification treatment was applied to the 200 single-rooted permanent teeth with the use of Angelus MTA, Ortho MTA, Retro MTA and Biodentine as 20 samples in each group. Coronal and apical leakage was assessed for each group; positive and negative control groups. For the microleakage test, samples were incubated in methylene blue, and then measured under a stereomicroscope. Sixteen specimens were prepared for evaluating the dentin adaptation. SEM examinations were performed by measuring micrometric measurements of the material and dentin spaces on the images of the apical and coronal regions. The obtained data were analysed statistically.
Results: According to the microleakage evaluation, apical and coronal measurements indicated significantly more leakage than Biodentine Angelus MTA and Retro MTA, but no significant difference was found to be between MTA groups (p<0.05). While there was no significant difference in the apical region between the groups dentin adaptation; in the coronal region, Biodentine was found to have more gap dimensions at the significant level than the other groups (p<0.05).
Conclusion: Biodentine was not as successful as the other groups in the microleakage and marginal adaptation.
