COMPARISON OF PIEZOSURGERY AND CONVENTIONAL ROTARY INSTRUMENTS IN IMPACTED THIRD MOLAR SURGERY

Study Overview
=================
Brief Summary
-----------------
The purpose is to compare the effects of piezosurgery and conventional rotary instruments on postoperative pain, swelling, trismus and patients' comfort after mandibular third molar surgery.

Detailed Description
-----------------
The investigators plan a prospective and split mouth study. Thirty patients will be randomly selected. Inclusion criteria were being older than 18 of age, having asymptomatic bilateral mesioangular impacted mandibular third molar (Pell and Gregory class II, position B) fully covered with mucosa and bone, and being otherwise medically healthy. One side of the patients will be randomly selected and labeled as experimental group. In experimental group, impacted third molar will be extracted using piezosurgery. The other side will be accepted as control group. In the control group, impacted third molar will be extracted using conventional rotary instruments.There will at least one month between two surgeries. The investigators will compare postoperative pain, swelling, trismus and patients' comfort.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| All the patients will be given a form containing verbal rating scale ranging from 0 to 5, showing the degree of swelling. | The edema measurement will be done during the one week after surgery. | Up to 1 week | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Pain will be assessed using a visual analogue scale. | The level of postoperative pain will be evaluated using a 10-cm visual analogue scale , with zero representing no pain and 10 representing excruciating pain. Pain measurement will be done preoperatively, postoperative 2nd day, 7th day after the surgery. | Up to 1 week | 
| Trismus will be evaluated using a caliper at maximum mouth opening. | Trismus will be assessed by measuring the maximum interincisal opening (in millimetres) - the distance between the incisal margin of the upper and lower central incisors. Trismus measurement will be done preoperatively, postoperative 2nd day, 7th day after the surgery. | Up to 1 week |
