TL;DR
This study compares how well different retrograde filling materials and preparation techniques prevent leakage in dental treatments.
Contribution
The study evaluates microleakage in retrograde filling materials using conventional and ultrasonic cavity preparation techniques.
Findings
MTA showed the least microleakage compared to Biodentine and One-Fil PT.
Ultrasonic preparation provided better sealing benefits than conventional techniques.
One-Fil PT exhibited significantly higher leakage than the other materials.
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.
