Evaluation of Sealing Ability of Calcium Silicate Materials with Diode Laser for Root Furcation Repair

Abstract

Background Inadequate furcation repair often leads to tooth loss due to accompanying endodontic and periodontal problems. An appropriate material and technique can prevent this. This study aimed to evaluate the sealing ability of Mineral Trioxide Aggregate MTA Glass Ionomer Cement GIC and Biodentine as a furcation repair material with and without laser.Methods Ninety human extracted mandibular molars were decoronated 3 mm above and below the cementoenamel junction. After access opening sticky wax was placed over the canal orifices. A defect of 1 mm diameter was made the chamber and perforation were flushed with water and dried. Further the specimens were divided into six groups based on the furcation repair materials used n 15. Group 1 MTA with laser Group 2 MTA Group 3 GIC with laser Group 4 GIC Group 5 Biodentine with laser and Group 6 Biodentine. In groups 1 3 and 5 diode 810 laser irradiation was done for furcal defect before placing the materials. Specimens were subjected to 2 methylene blue for 48 hr washed sectioned mesiodistally and depth of dye penetration was examined under stereomicroscope. Statistical software SPSS version 22 was used for analysis. One way analysis of variance followed by Post hoc Tukey multiple comparison test was done p le0.05.Results Among the experimental materials less microleakage was observed with laser activation than without using laser. Biodentine with laser Group 5 showed less microleakage which was statistically significant compared to all the other groups except group 6 i.e Biodentine without laser.Conclusion Biodentine with laser activation was effective in furcation repair and in prevention of microleakage.nbsp
