Abstract
This in-vitro study was performed to evaluate the effect of different FRC posts surface treatments on its bond strength to root canal dentin. Forty extracted human maxillary central incisors with fully developed apices, similar size and shape were selected for this study. There width were measured both buccolingually and mesiodistally in millimeters, allowing a maximum deviation of 10% from the determined mean. The specimens were stored in 1%Thymol solution. The coronal portion of each tooth was sectioned 15 mm coronally from the root apex using a diamond double-faced disc, in a slow-speed handpiece, cooled with air / water spray. The roots were embedded in selfcuring acrylic resin blocks.
