Aim: The purpose of this research was to compare the microleakage of different root-end filling materials. Materials and methods: Thirty human single-rooted teeth were decoronated at the cementoenamel junction, shaped with protaper rotary files, and obturated. About 3 mm apical resection of the roots was carried out and 3-mm deep rootend cavities were prepared using an ultrasonic retro-tip. The root-end cavities were then retrofilled with mineral trioxide aggregate (MTA Angelus) and biodentine, respectively, and submerged in 2% methylene blue dye for 24 hours. The depth of dye penetration and microleakage in each sample were recorded using a stereomicroscope. Results: Higher mean microleakage (mm) was recorded in MTA (2.40 ± 0.63) when compared to biodentine (1.60 ± 0.63) and the difference between them was statistically significant. Conclusion: Both the tested materials showed microbial leakage. Root-end fillings with biodentine had the lowest microleakage and better marginal adaptation as compared to MTA. Clinical significance: Biodentine showed better marginal adaptation and sealing ability when compared to MTA and can be considered as an alternative to MTA as a root-end filling material.
