Stereomicroscopic Evaluation of Sealing Ability of Three Different Furcal Perforation Repair Materials: An In vitro Study

Abstract

Background: The choice of sealing material is a crucial factor that influences the outcome of endodontic treatment. Aim: The purpose of this study was to compare the sealing ability of mineral trioxide aggregate (MTA) Angelus, Endocem MTA, and NeoPutty MTA when used as furcal perforation repair materials. Materials and Methods: A total of 45 mandibular molars were used. Root canal treatment was carried out following which standardized furcal perforations were made. The specimens were randomly divided into three groups of 15 teeth each. Group A‑Furcal perforation repair by means of MTA Angelus, Group B‑Furcal perforation repair using Endocem MTA, and Group C‑Furcal perforation repair by NeoPutty MTA. Following the repair procedure, the pulp chambers and access openings were filled with temporary restorative material and immersed in 1% basic fuchsin dye for 24 h. The teeth were sectioned longitudinally and the linear dye penetration was measured using a stereo‑microscope. Results: The one‑way analysis of variance (ANOVA) revealed a statistically significant difference among the groups (F = 16.15, P < 0.001). On calculating the depth of leakage to the total length of the perforation, it was observed that the mean leakage was 32.83% in Group I, 52.92% in Group II and the lowest, 16.35% in Group III. The ANOVA test reveals a statistically significant difference among the groups (F = 15.92, P < 0.001). Comparing the depth of dye penetration of dye, 33.3% of the Group I samples showed ≥50%, 49%–25%, and <25% dye penetration. Although 56.7% of Group II samples showed ≥50% dye penetration, whereas 63.3% of Group III showed <25% dye penetration. Conclusion: The present study indicated that NeoPutty MTA had the least dye penetration followed by MTA Angelus and Endocem MTA.
