Abstract
ABSTRACT. This research studied the adaptation and integrity between the cement, the fiber post and the root dentin in bovine teeth by analyzing the presence of bubbles in the interfaces involved in the luting of posts, different self-etch dependent resin type luting agents, self-adhesive resin luting agents and resin modified glass ionomer luting cement. Protocols were modified by way of cementing proposal for the better adaptation of luting agent to dentin substrate and fiber post. This study has shown that factors such as conditioning of the root canal dentin and the insertion technique of the fiber post with the luting agent significantly affect the results. Smeared post technique and the use of phosphoric acid as root dentin conditioner was questioned; on the other hand, an injection technique and the use of EDTA for dependent adhesive systems luting agents are proposed as well as the use of polyacrylic acid as a conditioner prior the use of resin modified glass ionomer cement.
