Comparison of the Sealing Ability of MTA-Angelus, Biodentine and CEM Cement in the Repair of Large Furcal Perforations-A Bacterial Leakage Study

摘要

Materials such as MTA-Angelus, Biodentine, and CEM Cement have been recommended for the repair of large furcal perforations. Due to larger surface area of such perforations, evaluating the sealing ability of the aforementioned repair materials is important for their clinical selection.Aim: To compare the sealing ability of MTA-Angelus, Biodentine, and CEM cement when used as repair materials for large furcal perforations.Materials and Methods: Sixty-five extracted human molar teeth were used for the study. Samples were randomly divided into groups 1, 2, and 3 with 20 samples in each (n=20). Five samples were used as controls. Furcal perforations of standardised diameter (2 mm) were prepared in samples of groups 1, 2, and 3 and repaired with MTA-Angelus, Biodentine and CEM Cement, respectively. A bacterial leakage model was used for each sample to study the sealing ability of these repair materials over an experimental period of 50 days. A culture of Enterococcus faecalis and sterile Brain Heart Infusion (BHI) broth were placed into the upper and lower chambers of the model, respectively. Any turbidity of the BHI broth indicated bacterial leakage through the repaired perforations. The day wise number of samples with bacterial leakage and the percentage of these samples during every five-day interval of the experimental period were noted and the results were statistically analysed using Chi-Square and Log Rank (Mantel-Cox) tests. The level of significance was set at p-value less than 0.05.Results: There was no significant difference in the bacterial leakage among the three groups at any 5-day interval of the experimental period (p>0.05).Conclusion: Biodentine and CEM cement with better handling properties could be used as alternatives to MTA-Angelus while repairing furcal perforations.
