ROOT END FILLING MATERIAL WHICH IS BETTER IN MARGINAL ADAPTATION? AN INVITRO STUDY.

Abstract

Introduction: The sealing ability of the root end filling materials to the wall can be assessed by the marginal adaptations. Various materials have been used in the past. This study was conducted to assess the root-end filling materials ProRoot MTA, Biodentine, RetroMTA’s marginal adaptation.

Materials and Methods: Ninety single-rooted teeth were divided to three equal groups of ProRoot MTA, RetroMTA and Biodentine. After the BMP and obturation, the third (3mm) of the root apex were cut, and cavities made with the ultrasonic technique. The transverse and the longitudinal sections were studied using the epoxy a replica under the SEM. One-way ANOVA was employed to associate the marginal gaps between the groups and P<0.05 was considered significant.

Results: Significant difference in the longitudinal gaps was observed when the three groups were compared. Conversely, in the transverse sections no significant differences were seen in the groups.

Conclusion: Biodentine yielded the best marginal adaptability when compared to the other two only in the longitudinal sections. Greater gaps were seen in the transverse sections in all the three groups.
