Abstract

Purpose: The aim of this study was to evaluate and compare the operative and postoperative outcomes of the mandibular impacted third molar removal using piezoelectric technique and conventional rotary bur technique.

Settings: The study was conducted in the department of oral and maxillofacial surgery between January 1, 2019, and January 1, 2020.

Materials and methods: Thirty patients, with an age of 18-40 years, with asymptomatic bilateral impacted mandibular third molars, were selected for the study and randomly surgical extraction was done either using piezoelectric or the conventional rotary bur technique on each site. The intraoperative time taken, postoperative pain, swelling, and trismus were assessed over a follow-up period of 7 days postoperatively.

Results: Study and control groups were compared using paired t-test. There was statistical significance in reduction of pain and swelling in the study group where the duration of surgery was increased in the study group.

Conclusion: Even if piezoelectric technique takes more time but can be used safely as another technique to conventional surgical method with surgical bur and handpiece for removal of impacted mandibular third molars.
