Aim and objective: This study aimed to evaluate the sealing ability of EndoSequence root repair material (ERRM), mineral trioxide aggregate (MTA), and glass ionomer cement (GIC) in the repair of furcal perforation.
Materials and methods: Thirty extracted mandibular molars were selected. After access cavity preparation of each molar, artificial perforation was made directly in the center of the pulp chamber floor. The teeth were randomly divided into three groups (N = 10) according to the used root repair material (RRM). The perforation sites were repaired with MTA (G1), ERRM (G2), and GIC (G3). The access opening of the teeth in all groups was filled with composite. Then, all teeth were immersed in 2% methylene blue for 24 hours and sectioned longitudinally to evaluate the maximum apical extent of dye leakage. Data were collected and analyzed statistically using ANOVA, Bonferroni, Kruskal–Wallis, and Mann–Whitney tests (p = 0.05).
Results: The less mean value of dye penetration was observed with MTA followed by ERRM and GIC. There was a significant difference among RRMs in relation to dye penetration. Both MTA and ERRM were significantly better than GIC in sealing the perforation site.
Conclusion: Mineral trioxide aggregate and ERRM showed a similar dye microleakage and had a better sealing ability when compared to GIC in this in vitro study.
Clinical significance: This current study showed the sealing ability of MTA, ERRM, and GIC while using to seal the furcal perforation during root canal treatment.
