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

A PROSPECTIVE SPLIT MOUTH CLINICAL STUDY: OF PIEZOSURGERY AND CONVENTIONAL ROTARY INSTRUMENTS IN IMPACTED THIRD MOLAR SURGERY

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.

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.

Inclusion Criteria:
