After Surgical removal of mandibular third molars, unavoidable side effects will happen which are mainly related to inflammation and can usually be managed with oral analgesics and NSAIDS. Lasers having analgesic, anti-inflammatory, bio stimulatory properties, and reduced side effects compared to drugs could be useful in this matter. The aim of this study was to evaluate the effect of Diode laser 810 nm on reducing pain after surgical removal of mandibular third molars.
Methods: This study was designed as random double blind controlled clinical trial and was performed on 20 patients having 2 similar and symmetrical impacted mandibular wisdom teeth. Two teeth in each patient were removed surgically within a 2-week interval and randomly one side was selected as experimental group which was irradiated by Diode laser total dose of 8J after surgery and on the other side as control group it was pretended to irradiate the socket but with no actual irradiation. Patients in both groups were allowed to use Gelofen in case of inadequate pain tolerance and they were asked to record the time and number of capsules taken. Level of pain during first three days after surgery was assessed. The results of this study were analyzed by Paired sample T-test and Wilcoxon rank test.
Results:
The results of this study showed that the mean of pain intensity at the day of surgery and during 48 hours after surgery and also number of Gelofens taken at the 1st, 2nd and 3rd day after surgery was significantly less than the placebo group.(P-value=0/0001).
Conclusions:
Since pain and amount of capsules taken were less in laser group, it can be concluded that the laser with the applied parameters in this study was better than control group in reducing post surgical side effects.
