Abstract
Aim: The present study aimed to assess the sealing ability of various repair materials in furcation perforations using dye penetration.
Background: Treatment options for furcal region perforations include conservative measures and surgery. The nonsurgical intermediate repair with a suitable restorative material appears to have the best prognosis since it will prevent the pulp chamber from communicating with the gingival sulcus, reducing infection and inflammation in the area.
Methods: A total of 75 human first molars (mandibular and maxillary) with unbroken enamel surfaces, which were extracted completely for periodontal reasons, were chosen. All extracted teeth were kept in a sterile solution up until further use. Endo-access bur was used to prepare endodontic access cavity, and a high-speed long shank round bur was used to create a planned perforation on the floor of pulp. All the specimens were randomly grouped (15 teeth in each group). A stereomicroscope (10×) was used to visualize the highest dye penetration.
Results: The least penetration was seen in teeth repaired by Biodentine group and Bio-C repair, next by Pro-Root MTA group and resin-modified glass ionomer cement group. A statistically significant difference was seen among different perforation repair materials by analysis of variance. A statistically significant difference (p value < 0.05) was found between each group.
Conclusion: This study concluded that, reduced dye penetration in perforation repair along the furcation and improved sealing ability are shown by Biodentine group and Bio-C repair group in comparison to Pro-Root MTA and Resin-modified glass-ionomer cement group. Further in vivo studies are required to prove its effectiveness.
