Effect of Targeted Endodontic Microsurgery on Quality of Life and Healing on Mandibular Molars

Targeted endodontic microsurgery represents precise and advanced approach to resolving persisting chronic periapical periodontitis after non- surgical root canal treatment. This specialised procedure involves accessing the root tip of the tooth under high magnification using dental operating microscopes and employing microsurgical instruments to remove infected or inflamed tissue, as well as any pathological lesions present in the periapical region. Targeted Endodontic Microsurgery is useful for osteotomy and root- end resection when exacting control of depth, diameter, and angulation of osteotomy and root end resection is necessary. Using a CBCT(cone beam computed tomography) designed 3D - printed surgical guideis a more accurate method for access to the apical portion of the root during surgical endodontics compared with a "freehand" CBCT - approximated conventional method. These guided have the potential to increase accuracy and precision and to reduce intraoperative time as well as postoperative complications. Additionally, it provides a viable treatment option for patients who may not be candidates for traditional root canal therapy or retreatment due to anatomical complexities or previous treatment failures.

Clinical and Radiographic Characteristics and Outcomes of Guided Apicoectomy With Retrograde Mineral Trioxide Aggregate Filling for Periapical Cysts

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.
