Comparing the Sealing Ability of Contemporary Restorative Materials

Abstract

ABSTRACT Aim The success of the root canal treatment mainly depends upon the three-dimensional obturation of the root canal system. The purpose of this study is to compare the sealing ability of biodentine, mineral trioxide aggregate (MTA), and glass ionomer cement (GIC). Materials and methods Teeth were obturated with gutta-percha using AH PLUS sealer in all groups. The intracanal sealing material used in group I was GIC, group II was MTA, and group III was biodentine. The specimens were longitudinally sectioned. Coronal microleakage was determined under a stereomicroscope using 15× magnification. Data were statistically analyzed using one-way analysis of variance followed by post hoc multiple comparisons (Bonferroni). Results Biodentine group leaked significantly less than the GIC group (p < 0.05). The sealing ability of biodentine was better than that of MTA, but the difference was not statistically significant. Conclusion Biodentine or MTA may be preferred over GIC as an intracanal barrier. Clinical significance Biodentine or MTA can be used in areas where an impervious seal has to be obtained. They can also be used to seal the perforations in the coronal middle and apical thirds of the root canal. These materials have an ability to form a barrier during apexification procedures.
