Brief Summary

This study is a prospective, randomized clinical trial comparing recovery after the surgical removal of impacted lower wisdom teeth. The aim is to evaluate swelling, pain, mouth opening, and quality of life after surgery.

The study was approved by the Ethics Committee of Harran University, and all patients gave written informed consent. It was conducted at the Faculty of Dentistry, Kahramanmaraş Sütçü İmam University. A total of 50 patients participated. They were randomly assigned to two groups: one treated with a piezoelectric device (study group) and the other with a conventional rotary handpiece (control group). All surgeries were performed by the same surgeon under local anesthesia.

In both groups, the tooth was removed, the bone edges were smoothed, the area was cleaned with sterile solution, and the gum flap was closed with stitches. In the piezoelectric group, the bone was removed using an ultrasonic piezoelectric system. In the conventional group, bone removal was performed with a surgical drill under irrigation.

After surgery, patients were followed for pain, swelling, mouth opening, and quality of life. Pain was measured daily for 7 days using a 10-point visual scale (0 = no pain, 10 = worst pain). Mouth opening was measured before surgery, on the 2nd day, and on the 7th day after surgery. Swelling was measured using 3-dimensional facial scans taken before surgery, and on the 2nd and 7th days after surgery. Quality of life was assessed with a short questionnaire (OHIP-14), completed before surgery and on days 2, and 7 after surgery. Higher scores meant a worse impact on daily life.

Conditions

Third Molar Extraction; Piezoelectric Technique

Study Design

• Allocation Method: RANDOMIZED
• Intervention Model: PARALLEL
• Primary Study Purpose: PREVENTION
• Blinding Strategy: SINGLE

Study Groups

Piezoelectric Surgery group

The group in which osteotomy during third molar extraction was performed using a piezoelectric device.

Group Type: EXPERIMENTAL

Third molar surgery with piezoelectric system

Intervention Type: PROCEDURE

For the surgical removal of the third molar with a mucoperiosteal flap, osteotomy was performed using a piezoelectric system under continuous irrigation. The mucoperiosteal flap was then repositioned and closed primarily with sutures.

Conventional Rotary Systems

The group in which osteotomy during third molar extraction was performed using a conventional rotary system.

Group Type: ACTIVE_COMPARATOR

Third molar surgery with Conventional Rotary System

Intervention Type: PROCEDURE

For the surgical removal of the third molar with a mucoperiosteal flap, osteotomy was performed using a conventional rotary system under continuous irrigation. The mucoperiosteal flap was then repositioned and closed primarily with sutures.
