Abstract

Innovations in periradicular surgery for failed treatment of orthograde root canal disease have been well-documented. We know of no prospective studies that have compared success rates of conventional methods with these presumed advances. In this prospective randomised trial we compare the use of an ultrasonic retrotip with a microhead bur in the preparation of a retrograde cavity. Outcome was estimated clinically by estimation of pain, swelling, and sinus, and radiographically by looking at infill of bone and retrograde root filling 2 weeks and 6 months postoperatively. Both methods used other surgical techniques including microinstruments to place the retrograde root filling. The success rate of the ultrasonic method was higher (all patients, n=26) than that of the microhead method (n=19 of 21). A larger study with longer follow up is required to consolidate this evidence.
