Overview

NCT ID: NCT07724964
Lead Sponsor: Can Tho University of Medicine and PharmacyOTHER
Official Title: Clinical and Radiographic Characteristics and Treatment Outcomes of Guided Apicoectomy With Retrograde Mineral Trioxide Aggregate Filling for Periapical Cysts in Premolar Teeth at Ho Chi Minh City Odonto-Stomatology Hospital
Brief Summary: Patients with periapical cysts associated with premolar teeth often require apical surgery when conventional endodontic treatment cannot resolve the lesion. Guided apicoectomy using a three-dimensional surgical guide may improve surgical accuracy while minimizing bone removal and reducing the risk of damage to adjacent anatomical structures.

This prospective single-arm interventional study aims to evaluate the clinical and radiographic characteristics of premolar teeth with periapical cysts and assess the treatment outcomes of guided apicoectomy with retrograde Mineral Trioxide Aggregate (MTA) filling. Forty-two participants will be treated and followed for six months. Clinical healing and radiographic bone healing will be evaluated one week, three months, and six months after surgery.
