Abstract

BackgroundReduction in postoperative complications is of vital considerations in impacted third molar teeth surgery. The aim of this study was to compare postoperative complications of impacted third molar surgeries for bone removal using laser, piezoelectric equipment, and conventional rotary instruments.MethodsTo address the research purpose, the investigator designed the prospective double-blind clinical trial study. The sample size was determined 20 (40 teeth) by sampling formula in any kind of operation. The data of patients were obtained in the different periods in terms of pain, trismus, swelling, ecchymosis, and patient’s satisfaction and then analyzed using SPSS 20 software via paired t test and Wilcoxon and McNemar’s tests.ResultsThe pain immediately after surgery and 2 days and 7 days after surgery was higher in the laser group. The swelling immediately after surgery was more in the laser group but not significant. The amount of mouth opening immediately after surgery and 2 days and 7 days after surgery was significantly lower in the laser group than in the piezosurgery group. The total duration of surgery and duration of osteotomy were significantly longer in the laser group. The patient’s satisfaction from surgery with piezosurgery was more than that with laser, but this difference was not significant.ConclusionDue to the rising demand for impacted wisdom tooth surgery, the present study suggests that hard tissue laser surgery and piezosurgery can clear the future of impacted molar surgery, and these approaches are more efficient in reducing postoperative complications compared to the conventional surgeries.

Highlights

Reduction in postoperative complications is of vital considerations in impacted third molar teeth surgery
Our results demonstrated that the pain immediately after surgery and 2 days and 7 days after surgery is higher in the laser group insignificantly (Table 1)
The swelling immediately after surgery is slightly higher in the laser group but not significant

Summary

Introduction

Reduction in postoperative complications is of vital considerations in impacted third molar teeth surgery. The aim of this study was to compare postoperative complications of impacted third molar surgeries for bone removal using laser, piezoelectric equipment, and conventional rotary instruments. The impacted third molar teeth surgery is one of the most common operations in dentistry [1]. Studies conducted in the USA represent the exorbitant cost of removal of impacted third molars [2]. This sort of surgery can be performed in some patients using forceps and elevator; on the other hand, surgical intervention appears to be necessary in other patient groups, such as lifting the flap and removing the bone tissue [3]. The major concern in this type of surgery is the risk of damage to nerve [10], especially to the inferior alveolar nerve and lingual nerve during impacted mandibular third molar surgery, which
