Aim: The purpose of this investigation was to evaluate the marginal adaptation of three root-end filling materials Glass ionomer cement, Mineral trioxide aggregate and BiodentineTM.
Methodology: Thirty human single-rooted teeth were resected 3 mm from the apex. Root-end cavities were then prepared using an ultrasonic tip and filled with one of the following materials Glass ionomer cement (GIC), Mineral trioxide aggregate (MTA) and a bioactive cement BiodentineTM. The apical portions of the roots were then sectioned to obtain three 1 mm thick transversal sections. Confocal laser scanning microscopy (CLSM) was used to determine area of gaps and adaptation of the root-end filling materials with the dentin. The Post hoc test, a multiple comparison test was used for statistical data analysis.
Results: Statistical analysis showed lowest marginal gaps (11143.42Â±967.753m2) and good marginal adaptation with BiodentineTM followed by MTA (22300.97Â±3068.883m2) and highest marginal gaps with GIC (33388.17Â±12155.903m2) which were statistically significant (p<0.0001).
Conclusion: A new root end filling material BiodentineTM showed better marginal adaptation than commonly used root end filling materials
