ABSTRACT:
A method for restoring a tooth by endodontically preparing the tooth to accept a dental post. Polyacrylic acid solution is supplied to the prepared area afterwhich it is rinsed out and the area dried. A drying agent has been applied to the prepared area and, likewise, the area is dried out. The dental post is then secured in place through the use of a cement. Preferably, the cement is a filled resin cement with the filler material being approximately 15%-30% of the cement. The drying agent is preferably an ethyl-methyl ketone. The invention also includes a kit containing the materials for implementing the method.
