Outcome of Bone Window Approach in Endodontic Microsurgery Using Novel Piezoelectric Device Versus Conventional Rotary Burs in the Treatment of Periapical Lesions - a Randomized Controlled Trial

What this Trial Is About

Researchers are evaluating the bone window approach in endodontic microsurgery to treat patients with large periapical lesions and an intact buccal cortical plate. This study compares the outcomes of using a novel piezoelectric device versus conventional rotary burs to create the bone window. The goal is to preserve more bone structure and improve healing, as traditional methods may cause slower or incomplete cortical bone regeneration. This trial is a randomized controlled study aimed at finding the better surgical technique for these dental conditions. The study involves two groups: one where the bone window osteotomy is created using a piezoelectric device, and the other using conventional rotary burs in a slow-speed handpiece. Both procedures are performed during endodontic microsurgery on patients with symptomatic apical periodontitis and periapical lesions. The piezoelectric device cuts hard tissue selectively while preserving soft tissues, potentially offering advantages over traditional burs. The trial lasts at least one year to assess healing outcomes. Participants will undergo clinical and radiographic evaluations one year after surgery, including cone-beam computed tomography (CBCT) to measure bone healing and lesion status. The study assesses clinical signs, symptoms, and radiographic evidence of healing in the surgical area. Researchers will monitor and compare the effectiveness of both surgical techniques in preserving bone and improving patient recovery. Total participation duration includes pre-surgical imaging, surgery, and follow-up assessments over one year.
