Ultrasonic preparation improves outcome in apical surgery.
June 29th, 2008 | by admin |Ultrasonic preparation improves outcome in apical surgery.
DesignThis was a randomised controlled trial (RCT).InterventionRoot-end resection and preparation with a round dental bur was compared with the use of ultrasonic diamond coated retro-tips.Outcome measureTreatment was considered a success when the radiological and clinical criteria listed (Table 1) were met.ResultsOut of a total group of 399 patients who were included in the study, adequate followup 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 was 70.9% (P 0.056). In molars, the difference in success rate was significant (P 0.02).ConclusionsThe use of an ultrasonic device in apical surgery showed a clear benefit over the traditional treatment. Especially in molars, the results were significant.Evidence-Based Dentistry (2008) 9, 53. doi:10.1038/sj.ebd.6400585.
