ObjectiveThe purpose of this study was to evaluate the potential benefit of an ultrasonic device in apical surgery on the outcome of treatment.Study designA randomized prospective design was used in a standardized treatment protocol. Patients were allocated to treatment with an ultrasonic device (P-Max Newtron) or treatment with a bur in an otherwise similar protocol. One year after treatment the results were evaluated by 2 oral and maxillofacial surgeons who were blinded for the therapy.ResultsOut of a total group of 399 patients who were included in the study, adequate follow-up could be obtained in 290 patients. The overall success rate in the ultrasonic group was 80.5% and in the group treated with a bur 70.9% (P = .056). In molars, the difference in success rate was significant (P = .02).ConclusionThe use of an ultrasonic device in apical surgery improved the outcome of treatment. In molars this effect was significant.
