Radiographic morphometric study of 37 periapical lesions in 30 patients: validation of success criteria.

Purpose: The purpose of this study was to establish the midterm prognosis of periapical surgery by use of the ultrasound technique, comparing a scale obtained by image analysis with the success rates according to other prognostic scales.
