Comparison of Sealing Ability of MTA and Biodentine for Repairing of Furcal Perforation in Primary Molars

* Preservation of the primary teeth is a mandatory issue for maintaining the integrity of the normal dentition and functioning till the eruption of the successors. * furcal perforations may occur due to iatrogenic and non-iatrogenic causes. * Despite the high successful outcomes in perforation repair with MTA, there are some issues which prevent the clinicians from using it for many cases such as its very long setting time and its difficult manipulation. * Biodentin could be used as an alternative to MTA in reparative treatment procedures due to its ability to provide a hermetic seal and durable restoration and thus an optimal sealing is expected. * The importance of the trial lies in testing the sealing ability of Biodentine using scanning electron microscope. Biodentine has short setting time and is easier in manipulation than MTA which are major needs when dealing with pediatric patients to be able to give best results in short time.
