Clinical and Radiographic Characteristics and Outcomes of Guided Apicoectomy With Retrograde Mineral Trioxide Aggregate Filling for Periapical Cysts
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
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.
연구 개요
상세 설명
Periapical cysts are common inflammatory lesions caused by pulpal infection and necrosis. Although conventional root canal treatment is effective in most cases, surgical intervention becomes necessary when persistent periapical lesions remain or true cysts develop.
Apicoectomy combined with retrograde filling using Mineral Trioxide Aggregate (MTA) has demonstrated high clinical success because of excellent sealing ability, biocompatibility, and stimulation of periapical tissue regeneration. Recently, computer-guided surgery integrating cone-beam computed tomography (CBCT), intraoral scanning, digital planning, and three-dimensional printing has improved surgical precision while minimizing unnecessary bone removal.
This prospective, single-center, single-arm interventional study will enroll 42 patients diagnosed with periapical cysts involving premolar teeth. Eligible participants will undergo guided apicoectomy, cyst enucleation, root-end cavity preparation, and retrograde filling with Mineral Trioxide Aggregate (MTA).
Clinical outcomes will be assessed one week, three months, and six months after surgery. Radiographic healing will be evaluated using cone-beam computed tomography (CBCT) at six months. The study aims to determine the effectiveness and safety of guided apicoectomy with MTA in treating premolar periapical cysts.

실험적: Guided Apicoectomy With Retrograde Mineral Trioxide Aggregate Filling
|
Patients undergo cone-beam computed tomography (CBCT) and intraoral scanning for digital treatment planning.
A three-dimensional surgical guide is fabricated to accurately locate the root apex.
Guided apicoectomy is performed with cyst enucleation, root-end resection, ultrasonic root-end cavity preparation, and retrograde filling using Mineral Trioxide Aggregate (MTA).
Standard postoperative medications and follow-up examinations are provided.
