Comparative Evaluation of Conventional Rotary Technique with Piezoelectric Technique in Removal of Impacted Third Molar
Journal Title: Indian Journal of Dental Advancements - Year 2019, Vol 11, Issue 1
Abstract
Context: Surgical removal of impacted third molars is often required to prevent clinical symptoms. While rotary cutting instruments have been traditionally and are still popularly used to remove impacted third molars, they are associated with high rate of pain and post-operative swelling. Piezosurgery is a newer technique that promises greater precision of cuts and lesser post-operative sequelae. Aims and Objectives: The aim of the present study was to compare the piezosurgery with rotary techniques in terms of their intraoperative and post-operative effects. Materials and Methods: A total of 40 patients, within the age of 18–40 years, with asymptomatic impacted mandibular third molars, were selected for the study and randomized into two groups. Group A consisted of 20 patients who underwent surgical extraction with rotary instruments and Group B consisted of 20 patients who underwent surgical extraction done with piezoelectric unit. The intraoperative time taken and tissue destruction was assessed and the post-operative pain, swelling, and trismus were assessed over a follow-up period of 7 days. Results: The mean time of surgery was 27.35 ± (3.1) min in Group A, whereas it was 53.65 ± (2.4) min in Group B. The mean incidence of tissue destruction was 0.8000 ± (0.41) in Group A, whereas it was 0.2000 ± (0.41) in Group B. The mean postoperative pain on day 0 was 5.05 ± (0.69) in Group A and 3.05 ± (0.69) in Group B, on day 3 was 3.20 ± (0.7) in Group A and 1.50 ± (0.69) in Group B, and on day 5 was 2.0 ± (0.73) in Group A and 0.40 ± (0.6) in Group B. On the 3rd postoperative day, mean post-operative swelling 2.51 ± (0.3) cm in Group A and mean post-operative swelling 1.2600 ± (0.28910) cm in Group B. On the 5th post-operative day, mean post-operative swelling was 1.4 ± (0.31) in Group A and 0.5650 ± (0.21095) in Group B. The difference between both groups was found to be statistically significant for all parameters. Conclusion: Although piezosurgery takes more time and is more expensive, the advantages gained in terms of tissue preservation, and decreased pain and swelling make it a superior technique compared to using rotary instruments in impacted third molar.
