A Comparative Study of Mandibular Cyst Enucleation Using the Piezoelectric Surgery Versus the Conventional Technique

Abstract

INTRODUCTION: piezosurgery device was originally developed for the atraumatic cutting of bone as it produces microvibrations and specific ultrasound frequency (25-29 kHz). This new ultrasonic cutting method will be an alternative to conventional methods of oral surgery. OBJECTIVES: This study compares the use of piezosurgery and conventional technique in mandibular radicular cyst enucleation and this was estimated by clinical and radiographic analysis. MATERIALS AND METHODS: This study was conducted on fourteen patients selected from the Outpatient Clinic of the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Alexandria University. Patients with radicular cyst in jaw region were diagnosed clinically and radiographically. The patients were randomly divided into two groups, seven patients were treated using piezosurgery and other seven patients were treated using conventional surgical procedures. Intraoperative and postoperative evaluation was carried out to monitor soft tissue damage, manipulation complexity, pain, infection and tissue dehiscence at 1 st , 2 nd , 7 th day and after one month postoperatively. The bone healing and bone density was determined radiographically after 3 and 6 months postoperatively using Cone Beam Computed tomography. RESULTS: no soft tissue damage or manipulation complexities were observed in both groups, less bleeding was observed intraoperatively in piezosurgery group. Healing was uneventful with no signs of dehiscence in piezosurgery group with lower pain score than in control group. There was a significant decrease in the surface area of the bone defect in the piezosurgery group compared to control group along the follow up period. The improvement in the bone density was greater in the piezosurgery group than in the control group, with percent of difference 33.42% on the 3 rd month and 63.84% on the 6 th month. CONCLUSIONS: Piezosurgery is effective in cyst enucleation as it accelerates bone healing and reduces intraoperative and postoperative complications.

Clinical and Radiographic Outcomes of Radicular Cyst Enucleation Using Piezosurgery Versus Conventional Surgery

“…Moreover, other studies comparing the piezosurgery to the conventional surgery have reported better healing, reduced bone loss and less complications associated with piezoelectric surgery. (21,22) To the best of our knowledge, this is the first study comparing the percentage of reduction in bone defect volume after cyst enucleation using piezosurgery versus conventional surgery. The CBCT software enabled the calculation of bone defect volume in the 3 dimensions which gave a more accurate picture of spatial bone healing than just measuring the 2-dimensional surface area done in previous studies.…”
