Abstract

The purpose of the study was to compare piezo surgery and low speed rotary hand piece technique with regard to surgery time, pain, swelling, and trismus after removal of impacted lower third molars .Twenty patients selected from the Outpatient Clinic, Department of Oral and Maxillofacial Surgery, Faculty of Dental Medicine, Al Azhar University, Cairo, Boys. Their ages ranged from 19 to 30 years old. All patients complained of mesio-angular impacted lower third molar. Patients were divided randomly into two groups (10 patients each). All the patients were subjected to osteotomy around the impacted mandibular third molar using either piezo tome (test group) or the conventional technique (control group). The patients were evaluated after surgery at first, third, fifth, seventh and fifteenth day to evaluate pain, trismus and edema. Results: It was revealed that the difference between the two groups in pain and trismus was statistically significant in all days where test group recorded lower value than in control group except fifteenth day in evaluation of trismus. The difference between two groups in evaluation of edema was significant in clinical evaluation but not statistically significant in all days. Conclusion: Piezo surgery is an excellent tool for reducing the risk of complications and improving of the patient’s wound in whole postoperative period.
