AIM: The study was intended to evaluate the effectiveness of piezosurgery in enucleation of radicular odontogenic cysts in comparison to the conventional technique from both the clinical and radiographic perspectives.
METHODS: Fourteen (8 females and 6 males) patients with age range of 30-55 years who had radicular cysts associated with non-vital teeth, were operated at the Oral and Maxillofacial Surgery Department, Faculty of Dentistry, Alexandria University. The patients were randomly divided into 2 groups;1) the study group (7 patients) in which cyst enucleation using piezosurgery was employed, 2) control group in which the cysts were removed using the conventional technique. The following parameters were assessed; postoperative pain, time of operation, hemorrhage control and field visibility, ease of operation, neurosensory evaluation and radiographic percentage of change in bone defect volume between preoperative and 3-months postoperative values.

Piezosurgery: SATLEC ACTEON peizotome 2 (A company of ACTEON Group, France) was used. Conventional surgery with rotary instruments
Faculty of dentistry-Alexandria University
Alexandria, Egypt
Time of operation in minutes
Time from start of the incision to the last suture.
Time frame: Intraoperative
Hemorrhage control and ease of operation using a visual analogue scale
To assess the visibility of the field and ease of operation, a visual analogue scale was used. Each parameter constituted a horizontal 100 mm continuous line in which value of zero indicates minimum level of the assessed parameter and 100 indicates the maximum level. Each surgeon marked on the line then the score is determined by measuring in mms from the left end of the line to that marked point. (higher scores mean a better outcome)
Time frame: Intraoperative
Objective assessment of neurosensory function using a probe (to detect nerve injury after the surgeries)
A probe was used to prick the patient's skin relevant to the area of operation to assess the neurosensory function in comparison to the contralateral side.If the patient states a difference in sensation between the side of operation and the normal side, it was assigned as "Y" and if there was no difference in sensation between the two sides, it was assigned as "N".
Time frame: 1 month
Radiographic percentage of change in bone defect volume using cone beam computed tomography
The change between preoperative and 3-months postoperative values of both groups were compared
Time frame: 3 months
