The Effect Of Root Canal Irrigants On The Push –out Bond Strength Of Biodentine

Root perforation connect root canal spaces with periodontal tissues. The connection may occur as result of iatrogenic causes during root canal treatment (at the level of floor of the coronal cavity or at different levels of the root) or during prosthetic treatment of post canal trioxide aggregate(MTA), composite resin, glass ionomer cement and calcium hydroxide, most of these penetration. (1) An ideal perforation repair material should provide a tight seal between the materials show significant short comings in one or more of the following areas: solubility, leakage, biocompatibility, handling properties, and moisture incompatibility. (4,5) Despite the numerous favorable properties of MTA that support its clinical use when compared with the traditional materials, there are several critical drawbacks such
