Comparative evaluation of apical microleakage of biodentine and mineral trioxide aggregates (mta) as an apical plug material in 5mm thickness in single rooted permanent teeth-an in vitro study

Introduction: To enhance the success rate of periapical surgery it is of utmost importance to have fluid Seal in apical third of root canal, this study comparative evaluation of apical microleakage of biodentine and mineral trioxide aggregates (MTA) as an apical plug material in single rooted permanent teeth with the help of a UV-VIS spectrophotometer. Material and Method: 23 human single-rooted extracted tooth were selected free from cracks and caries and similar anatomical characteristics. The teeth were decoronated using a diamond disk bar in an underwater stream aerator handpiece to create a standardised root length of 16 mm working length of canals of all teeth was adjusted to 15.5 mm. Biomechanical preparation (BMP) was done using rotary pro taper file upto # F4. Apical plug materials were placed as follows---(20 tooth out of 23 tooth) Apical barrier placed 5mm (10 teeth) with Biodentine,and 5mm (10 teeth) with MTA and 3 tooth are control group and remain canal obturation done with G.P point and AH PLUS sealer .Microleakage was tested by using 2% methylene blue dye extraction method with the help of UV-VIS spectrophotometer. Result: The apical barrier of 5mm thickness demonstrated less microleakage of Biodentine than MTA. Biodentine has better sealing ability than MTA as an apical plug material in single-rooted teeth in apical thicknesses (5 mm). Conclusion: The observation of the present study was the apical barrier of 5mm demonstrated less microleakage of Biodentine than MTA.
