چکیده
The aim of this study was to compare the effectiveness of white mineral trioxide aggregate and gray mineral trioxide aggregate with different thicknesses and light curing glass ionomer cement when used as a barrier material in intracoronal bleaching procedures. In this study, 130 freshly extracted, caries free human permanent single rooted maxillary canine teeth were used. The teeth were randomly divided into six experimental groups, and positive and negative control groups. The specimens in the experimental groups 1, 2 and 3 received white mineral trioxide aggregate, gray mineral trioxide aggregate and light curing glass ionomer cement with a thickness of 2 mm, respectively. The specimens in the experimental groups 4, 5 and 6 received white mineral trioxide aggregate, gray mineral trioxide aggregate and light curing glass ionomer cement with a thickness of 5 mm, respectively. The positive control group received no barrier material and the negative control group did not undergo bleaching. There was no difference in leakage between gray mineral trioxide aggregate and white mineral trioxide aggregate (p>0.001). In conclusion, both gray and white mineral trioxide aggregate provided good coronal seal and decreased the amount of coronal leakage.

Introduction: Cervical root resorption is one of the most important complications of intra coronal bleaching. A way of preventing this type of resorption is using a coronal barrier under the bleaching materials. The aim of this study was to compare the sealing ability of glass ionomer cement and Pro Root Mineral Trioxide Aggregate (MTA) as a coronal barrier in intra coronal bleaching. Materi...
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...
