Sealing ability of three different root repair materials for furcation perforation repair: An in vitro study

Aim: The present study aimed to evaluate and compare the sealing ability of mineral trioxide aggregate (MTA)-Angelus, Biodentine™, and EndoSequence cement in furcation perforations using protein leakage assessment.

Materials and methods: The present study was conducted using seventy extracted human maxillary and mandibular molars with intact furcation. The samples were randomly allocated into three groups (n = 20) based on repair material used: Group 1 - MTA-Angelus, Group 2 - Biodentine™, and Group 3 - EndoSequence. Two additional groups served as positive and negative controls (n = 5). Using the leakage assessment apparatus, the presence of protein was detected with a reagent (Coomassive Brilliant Blue) every day for 60 days. One-way ANOVA and post hoc Tukey's test were used for statistical analysis using SPSS software.

Results: All the groups exhibited protein leakage from day 1. Biodentine showed minimum (0.1201 mg/ml), MTA showed maximum (0.3738 mg/ml), and EndoSequence had intermediate (0.2465 mg/ml) leakage. None in the negative control and all of the positive control specimens leaked during the experimental period of 60 days.

Conclusion: The newer biomaterials, Biodentine and Endosequence with better handling properties, could be used as alternatives to MTA-Angelus while repairing furcation perforations.
