Abstract

Retrograde filling success largely depends on the sealing ability of the material and the quality of the cavity preparation technique. Therefore, it is of interest to compare apical microleakage among MTA, Biodentine and One-Fil PT using conventional bur and ultrasonic retrograde cavity preparation. One hundred prepared teeth were restored, dye-immersed, sectioned and evaluated under a stereomicroscope for leakage. MTA showed the least microleakage, followed by Biodentine, while One-Fil PT exhibited significantly higher leakage. Within study limitations, MTA remains the most effective retrograde filling material, with ultrasonic preparation offering additional sealing benefits.
