Mineral Trioxide Aggregate Versus Biodentine as Retrograde Filling Material- A Clinical Review

Abstract

BACKGROUNDThe ultimate goal of root canal treatment is to seal the root canal both apically and coronally through obturation and restoration in order to prevent recontamination of the disinfected canals. Even after root canal treatment, there can be problems due to failure. The major causes of root canal failure are persistence of microbes or entry of microbes through coronal or apical leakage. If the reinfection occurs, in most of the cases surgical intervention is required followed by retrograde filling to achieve hermetic apical seal. Various retrograde filling materials have been advocated but MTA was found to be more appropriate as the literature suggested. However, Biodentine has also been used since last few years. The aim of the retrograde filling is to seal the canal in order to prevent passage of bacteria or their toxins from the canal space into peri-radicular tissues and vice versa. MTA and Biodentine has been shown to have a biocompatible nature and have excellent potential in endodontic use.The aim of this article is to comparatively review the properties such as biocompatibility, sealing ability, antibacterial effect and tissue response in both MTA and Biodentine as root-end filling material.
