The aim of the study was to evaluate the effect of Piezosurgery and Trephine bur as cutting tools on post-operative sequelae including pain and swelling following guided endodontic microsurgeries.
Materials and Methods: Twenty healthy male patients aged between 18 and 45 years old were selected in the study. Mandibular first molar teeth with failed non-surgical treatment or re-treatment due to iatrogenic errors at the apical 3mm of the mesial root canal including canal ledging, zipping and transportation, root perforation, separated instrument, and canal calcification were selected. Piezosurgery assisted cavity preparation and root-end resection were performed in Groups I and II, and Trephine bur assisted cavity and root-end resection was performed in Groups III and IV. An apical curettage was performed and the over-extended objects such as separated instruments or gutta percha were removed. The PRF clots was placed inside the bone cavity in groups I and III while the bone cavity was kept for 2 min to allow the blood clots to be formed in groups II and IV. The degree of pain and swelling were recorded for five days every 24, 48, 72, 96, and 120 hours postoperatively.
