Evaluation of Effectiveness of Mineral Trioxide Aggregate for Root Furcation Repair Using Diode Laser as Adjunct - An In Vitro Study

Abstract

Background Most of the materials used for furcation perforation repair often leads to microleakage. Therefore novel techniques to prevent this are needed. This study aimed to determine the ability of Mineral trioxide aggregate MTA and Ethoxy benzoic acid Super EBA along with laser for sealing the root furcation.Methods About 108 human-extracted mandibular molar teeth were decoronated at directly above and beneath the furcal area. After access opening the canal orifices were closed with sticky wax. A furcal defect of 1 mm width was prepared. The specimens were allocated into six groups for furcation repair n18. Group 1 MTA Group 2 Super EBA Group 3 Laser MTA Group 4 Laser Super EBA Group 5 positive control Unrepaired furcal defect and Group 6 negative control Intact furcation. In Groups 3 and 4 furcal defects were irradiated with diode 980 nm laser before placing the materials. All specimens were submerged in 2 methylene blue solution for two days were cleaned with sterile water and sectioned mesiodistally. Microleakage was assessed using stereomicroscope. Data was analysed using SPSS version 22. One-way ANOVA and Post hoc Tukey tests were used P le0.05.Results Except for the MTALaser all groups demonstrated decreased microleakage which was statistically significant. The positive control group showed highest microleakage and the negative control group showed none.Conclusion MTA as adjunct to laser activation is effective in preventing microleakage in furcation defects.nbsp
