Abstract

The use of the dental adhesive resin cement Panavia 21 (Kuraray, Japan), which showed strong adhesion to a dentin surface pretreated with H3PO4 and NaClO, was previously reported. This dentin bonding system is considered to be effective not only for restoration but also for rebuilding an abutment tooth. The purpose of this study was to evaluate the microleakage in three different core systems using this dentin bonding system. The three core systems were:(1) cast core, (2) resin core with a manufactured post, and (3) resin core without a post. Stress loading and thermal cycling were performed on the specimens, and microleakage was evaluated by the dye penetration test.<BR>The results were as follows:<BR>1. A resin core without a post showed a higher dye penetration rate than a resin core with a manufactured post.<BR>2. There was no significant difference between a resin core with a manufactured post and cast core under stress loading and thermal cycling.<BR>3. A resin core with a manufactured post using this dentin bonding system was evaluated to be as effective as a cast core.
