Evaluation Of Sealing Ability Of Biodentine, MTA Angelus And Zirconia-Reinforced Glass Ionomer Cement For Repairing Furcation Perforations : An In Vitro Study . National Journal of Integrated Research in Medicine. 2022 Jun; 13(4): 18-220975-98402230 - 9969http://imsear.searo.who.int/handle/123456789/219882Background:Background and objective: One of the unfavourable outcomes of endodontic treatment is furcal perforation. Materials such as MTA-Angelus, Biodentine and Zirconomer have been recommended for the repair of furcal perforations.In this study we compared the sealing ability of MTA-Angelus, Biodentine and Zirconia-reinforced GIC in furcal perforations using dye penetration method. Material And Methods:Access cavities were prepared in extracted mandibular molars (n= 40) using round bur in a high speed hand pieceunder water coolant. Perforations were made in the centre of furcation region using 2mm round bur.The teeth were randomly divided into 4 groups based on the material used to seal the perforation: Group I(n= 12) = MTA –Angelus , Group II (n=12)= Biodentine, Group III(n=12) = Zirconomer , Group IV (n= 4) = left unsealed (negative control group).Leakage at the repaired site was then evaluated using methylene blue dye penetration technique under stereomicroscope and data was statistically analyzed.Result:Minimum dye penetration was observed in biodentine followed by MTA, Zirconomer and control group. The results was not statistically significant (p= .08). Conclusion:According to this study, biodentine showed best of the three materials used for furcation repair.BiodentineFurcal PerforationsMTA –AngelusScanning Electron MicroscopeZirconomerJournal ArticleIndiaSenior Lecturer,Department Of Conserva tive Dentistry & Endodontics, Rungta College Of Dental Sciences & Research, Kohka,Kurud,Bhilai, C.GProfessor,Department Of Conservative Dentistry & Endodontics, Maitri College Of Dentistry & Research Centre, Anjora , Durg,C.GProfessor & Hod,Department Of Conserva tive Dentistry & Endodontics, Shri Yashwantrao Chava n Memorial Medical & Rural Development Foundation’s Dental College& Hospital, AhmednagarPriva te PractisionerSenior Lecturer,Department Of Conserva tive Dentistry & Endodontics, Mansarovar Dental College,Bhopal
