Aim:
The purpose of this in-vitro study was to compare and evaluate the best sealing ability of five different root end filling materials i.e. Silver Amalgam, RMGIC, Cermet Cement, MTA Angelus and Biodentine using ConFocal Laser Scanning Microscope.
Methods And Material:
90 extracted caries free, maxillary incisor teeth were collected and were root canal treated using standardized technique. Apical root resections followed by retrograde cavity preparation were done with ultrasonic retrotip. The teeth were divided into six groups depending upon different root end filling materials (Amalgam, RMGIC, Cermet cement, MTA, Biodentine) and one control group and apical leakage was observed under confocal laser scanning microscope.
Statistical Analysis Used:
The data was analyzed by ANOVA and Post Hoc test.
Results:
The mean dye penetration of different groups were Group I (Control Group) 0.00±(0.00) mm, Group II (Silver amalgam) 3.00±(0.00) mm, Group III (RMGIC) 1.84±(0.26) mm, Group IV (Cermet cement) 1.83 (0.25) mm, Group V (MTA) 1.25±(0.12) mm, Group VI (Biodentine) 0.26±(0.21) mm.
Conclusion:
It was concluded that Biodentine exhibits best sealing ability followed by mineral trioxide aggregate, followed by Cermet Cement and RMGIC, whereas silver amalgam exhibited least sealing ability.
