ObjectiveThe purpose of this prospective clinical study was to monitor the outcome of ultrasonic root-end preparation, in relation to tooth type and location, presence of post restoration and type of retrotip.Study designTeeth treated surgically showed a periradicular lesion of strictly endodontic origin. Fifty teeth were included in the study, according to specific selection criteria. Cases were followed for a period of 1 year and then classified in 3 groups (success, uncertain healing, and failure) according to radiographic and clinical criteria.ResultsOf the 46 teeth evaluated at 1-year follow-up, 42 teeth (91.3%) successfully healed, 1 tooth had uncertain healing, and 3 failed. We found no statistically significant differences in treatment results related to the type of tooth, tooth location, post restoration, and type of retrotip.ConclusionAdherence to a strict endodontic surgical protocol and the use of contemporary techniques and materials can lead to a predictable outcome.
