Abstract:

Purpose: The aim of this study was to evaluate and compare the effects of piezoelectric surgery and rotary instruments on the inflammatory response in the impacted lower third molar surgery. Patients and Methods: Twenty-six healthy patients with symmetrically impacted mandibular third molars were included. In the first operation, buccal osteotomy was performed with a round burr (Rotary group). In the second operation, piezoelectric surgery was used for bone removal (Piezo group). Duration of surgery, pain, trismus and cheek swelling were evaluated. Results: The average duration of surgery was significantly longer in the piezo group (p=0.003). On the second postoperative day, the average VAS pain scores during rest (p=0.005) and chewing (p<0. 001) and on the seventh postoperative day during chewing (p<0.001) were significantly higher in the rotary group. On the seventh postoperative day, the number of analgesic tablets taken in the piezo group was significantly lower than the rotary group (p=0.013). The average facial swelling in the rotary group was significantly higher than the piezo group on the second postoperative day (p<0.001) and on the seventh postoperative day (p=0.003). On the second (p<0.001) and seventh postoperative days (p<0.001) trismus was significantly higher in the rotary group. Conclusion: According to the findings of the present study, piezoelectric bone surgery is an alternative method to reduce morbidity and to improve recovery after impacted third molar surgery.
