Comparative Evaluation of Sealing Ability and Marginal Adaptation of Furcation Repair Materials: ...

The aim of this study was to see how well the furcation repair materials GC Fuji VII, MTA Plus, and Biodentine sealed. A combination of symptomatic findings in clinical observations is needed to diagnose iatrogenic perforation. Mechanical or abnormal communications between the root canal system and the external tooth surface are referred to as perforations. The research was carried out at the Himachal Dental College's Department of Conservative Dentistry and Endodontics in Sundernagar, Himachal Pradesh, India. The research used fifty-five sound mandibular molars with non-fused and well-developed roots. The specimens were analysed using a scanning electron microscope (SEM) with a vacuum of approximately 15Kv and 10-6 Torr. Secondary electrons were used to image the specimens, which were detected using a secondary electron detector. MTA plus has the smallest marginal distance at 2.17 micrometres, followed by Biodentine at 5.55 micrometres and GC FUJI VII at 8.00 micrometres, according to SEM images. The location of the perforation, the time elapsed between the occurrence of the perforation and repair, the ability of the material to seal the perforation, and the biocompatibility of the repair material are the most critical factors determining the effectiveness of a perforation repair operation. In comparison to GC FUJI VII and Biodentine, MTA Plus had the least amount of leakage in our sample. The MTA Plus group had the lowest microleakage, which could be due to its superior marginal sealing capacity, which is a function of its hydrophilic properties and the formation of an inter facial layer. When used as a furcation repair material, Biodentine offers a strong seal that is almost identical to MTA Plus. Biodentine and MTA Plus demonstrated substantially more leakage and gap formation than GC Fuji VII.
