ScandonestⓇ, a short-action dental local anesthetic, is supplemented without vasoconstrictor, preservative or antioxidant. Therefore, the anesthetic could be useful for pediatric patients. However,only a few clinical studies have been reported to date in Japan.In this study, we aimed to investigate the clinical utility of ScandonestⓇin pediatric dentistry. The subjects of this study comprised 148 patients in need of local anesthesia for dental treatment at the Dental Hospital, Tokyo Medical and Dental University. We administered a questionnaire to the patients and their dentists. Each dentist chose and used one of the following five kinds of local anesthetic : ScandonestⓇ, CitanestⓇ, Citanest with OctapressinⓇ, XylocaineⓇand ORAⓇInj. Cartridge.The results indicate that the anesthetic effect and pain during dental treatment are comparable among these anesthetics. There were significant differences in discomfort level after dental treatment,and the discomfort from ScandonestⓇtended to be less compared to the other anesthetics.These results suggest that ScandonestⓇcould be used as an effective local anesthetic, performing similarly to other anesthetics. Therefore, except for invasive treatments and dental treatments lasting longer than 30 minutes, ScandonestⓇwould be useful in pediatric dentistry.
