Abstract

<p>Abstract : The purpose of this study was to evaluate a new root-dentin adhesion method for vertical root fractures in endodontically treated teeth. The new root-dentin adhesion method consists of the elimination of infected dentin, followed by root-adhesion by 4-methacryloxyethyl trimellitate anhydride, methyl methacrylate and tri-n-butyl borane (4-META/MMA-TBB) and fiberposts. The elimination of infected dentin is expected to inhibit root perforation when using an apex locator for measuring the distance to the tooth root surface during grooving for enlarging the tooth cracks. Ninety-two teeth with vertical root fractures were treated by this method under a dental operating microscope. Clinical symptoms and radiographic appearance of bony lesions were followed up from 12 to 46 months. The success rate of treatment was 96.0%.</p><p> The results showed that the new root-adhesion method using the apex locator is an effective therapy for teeth with vertical root fractures without extracting the tooth.</p>
