The purpose of this study is to investigate clinical effects of "GP-solvent" as a new solvent to remove root canal filling materials. The results were summarized as follows : 1. With clinical use of GP-solvent in the 43 cases which required endodontic retreatment, the average number of visits for total endodontic treatment was 3.5 in 4 acute periapical periodontitis cases, 2.8 in 39 chronic periapical periodontitis cases. 2. The average time was 4.3 minutes per 1 root canal for K-files to arrive presumably at the root canal filling materials, and it was 8.4 minutes per 1 root canal before the root canal filling materials were thought to have thoroughly been removed. 3. According to the radiographic judgement on the degree of removal of root canal filling materials, 29 teeth (67.4%) were good, 14 teeth (32.6%) were fair and no tooth was poor. 4. As to the reactions to the smell of GP-solvent, 14 (48.3%) of a total of 29 patients were good, 15 (51.7%) were fair and no discomfort was complained. The above results and biological safety in preliminary studies show that GP-solvent is an effective root canal material solvent for clinical application.
