Effect of Diamond Bur and Root Canal Irrigants on Retention of Fiber Posts
… a diamond roughening instrument is used prior to cementation with self-adhesive resin cement. Forty-five (n=15) extracted human premolar teeth were sectioned at the cemento-enamel junction to obtain root length of fifteen millimeters. Endodontic instrumentation and obturation was performed. Post …

Evaluation of implant restoration retention on various custom abutment materials and surfaces
Purpose: Clinical use of cement-retained implant crowns requires selecting the appropriate abutment materials, surface characteristics, and cement type, based on finding the right balance between the desired level of retention form and the potential need for retrievability for each patient case. …

The Degradation of Resin Materials Bonded to Dentine in the Root Canal by the Activation of Matrix Metalloproteinases
Despite all the improvements resin based adhesive dental restorative materials have gone through in the last two decades, leakage in the resin-dentine interface is still a major limitation of resin based dental restorative materials. Dentine matrix metalloproteinases have been associated with this …
