Effects of the method of mechanical root canal treatment on emergence of pain after endodontic management

摘要

For assessment of tooth canal mechanical preparation method influence upon frequency of pain emergence after endodontic treatment, laboratory and clinical evaluation of sound tools of the Sonic system, ultrasound tools of the Satelec Suprasson system, full-wind tools of Pro Taper and System GT as well as handy K-files was performed. It was found that the least risk of pain emergence after endodontic treatment occurs with tooth canal widening by CrownDown technique because in this case the minimal amount of canal preparation products are educted into periodontal tissues.
