coronal microleakage of three different dental biomaterials as intra-orifi ce barrier during nonvital bleaching
background: this study was designed to assess the microleakage of glass-ionomer (gi), mineral trioxide aggregate (mta), and calcium-enriched mixture (cem) cement as coronal orifi ce barrier during walking bleaching. materials and methods: in this experimental study, endodontic treatment was done for 70 extracted human incisors without canal calcifi cation, caries, restoration, resorption, or cr...
متن کاملMicroleakage comparison of resin modified glass ionomer and OrthoMTA used as a coronal barrier in nonvital teeth bleaching
Background and Aim: Common causes of dental discoloration include trauma, drugs, genetic defects, decay, and age. In order to correct discoloration of pulpless teeth, internal bleaching is recommended. The aim of this study was to compare microleakage of resin modified glass ionomer and OrthoMTA used as an intraorifice barrier in non-vital bleaching. Materials and Methods: In this experimental ...
متن کاملA Comparative Investigation of the Microleakage of Biodentine and Mineral Trioxide Aggregate as Coronal Barrier in Nonvital Bleaching
Background and purpose: Internal bleaching is recommended to correct the discoloration of pulpless teeth. This study aimed to compare the microleakage of biodentine and mineral trioxide aggregate (MTA) used as an intracanal barrier in non-vital bleaching. Materials and methods: An experimental study was performed in which 36 extracted mandibular premolars were randomly divided into two experim...
متن کاملComparison of coronal microleakage of resin modified glass ionomer and composite resin as intra-orifice barriers in internal bleaching
Introduction: Internal bleaching is a treatment option for wightening endodontically treated discolored teeth. Cervical resorption is one of the side effects of this method.The aim of this study was to compare the sealing ability of resin composite and light-cured resin modified glass ionomer (RMGI) as intra-orifice barriers in internal bleaching. Materials &Methods: In this study, 34 single...
متن کاملMicroleakage comparison of glass-ionomer and white mineral trioxide aggregate used as a coronal barrier in nonvital bleaching.
OBJECTIVES There is some evidence that the pH at the root surface is reduced by intracoronal placement of bleaching pastes, which is known to enhance osteoclastic activity. Therefore, it is recommended that a protective barrier be used over the canal filling to prevent leakage of bleaching agents. Glass-ionomer (GI) is commonly used as a coronal barrier before nonvital bleaching. Because minera...
