The study of bone healing after endodontic microsurgery using cone beam computed tomography: A retrospective cohort study.

The CBCT data evidenced a significant volume reduction of 79.1%, with a monthly volume reduction rate of 6.2 mm3. The success rate obtained was 93%. Patient age and sex, dental arch and cortical bone influenced preoperative volume, tooth type had an impact upon the volumetric changes, and the preoperative symptoms influenced healing outcome. Cone beam computed tomography, endodontic microsurgery, healing, lesion volume, prognostic factors.
