Abstract:
This in-vitro study was done to compare the sealing ability of Mineral trioxide aggregate (MTA), Biodentine, a mixture of MTA and Glass ionomer cement (GIC) in 2:1 and 1:1 ratio and MTA CEM, as furcation repair material using a dye extraction leakage model in the department of Conservative Dentistry and Endodontics from January 2020 to December 2020. Eighty five extracted molars with divergent and well formed roots were selected for study and were randomly divided according to the material used for perforation repair. Group A: MTA, Group B: Biodentine, Group C: MTA mixed with GIC in 2:1 ratio. Group D: MTA mixed with GIC in 1:1 ratio. Group E: MTA CEM and 2 control groups. All samples were subjected to orthograde and retrograde methylene blue dye challenge followed by dye extraction with 70 weight % nitric acid. Samples were then analyzed using Ultra violet (UV) Visible Spectrophotometer at 550nm wavelength. The data were subjected to statistical analysis One Way ANOVA (level of significance <0.05) and post-hoc tukey test. MTA, Biodentine, Mixture of MTA and GIC in 2:1 ratio and MTA CEM showed significant less dye absorbance than MTA and GIC in 1:1 ratio. Within the limitation of the study, the newer mixture of MTA and GIC in 2:1 ratio showed promising sealing ability and was comparable to MTA, Biodentine and MTA CEM.
