NCT07184151•Suez Canal University

View on ClinicalTrials.gov

Summary

The aim of this study was to evaluate the effect of guided endodontic microsurgical root end resection on bone healing compared to nonguided microsurgery using two different retrograde filling material (Well root putty, MTA) by cone-beam computed tomography.
