Background and Objective: One of the great challenges in dental practice is root perforation sealing. At present time, there are two therapeutic methods for perforation, filling and surgical removal of affected area. In this in vitro study, we compared the sealing ability of two implanted materials, Iranian domestic Mineral Trioxide Aggregate (Root MTA) and foreign (Pro root MTA).
Materials and Methods: In this experimental study, 58 selected maxilary and mandibular molar teeth were assigned into four experimental groups of 13 teeth and 2 groups of three teeth as control. Availability of the cavities was assessed prior to perforating of the furcal areas utilizing a No. 2 round bur. The defects were then filled using foreign MTA (Pro root) and Iranian MTA. All of the subjects were incubated for 72 hours. In the next step, nail polish was applied in two layers to the surfaces of the teeth, except for the perforation areas and coronal portions which were filled with Amalgam. Once the nail polish dried, they were placed into 2% fuchsine solution for 12 hrs. The teeth were then mesio-distally resected using 72mm disk and evaluated separately by two endodontists using a stereomicroscope with a magnificantion of × 20. Data were analysied by T-test and ANOVA.
Results: Results indicated that there was a significant difference between the two groups regarding dye leakage (p=0.025). Pro MTA showed a lower leakage compare to Iranian MTA (root MTA).
Conclusion: The quality of Root MTA as a filling material may need to be improved in order to gain enough qualification as an alternative to Pro root MTA.
Key words: Root MTA, Furcal Perforation, Pro Root (MTA), Dye Leakage, Seal Ability
