Use of diode laser after surgical removal of impacted lower third molars

Objective: The purpose of this study was to evaluate the possibility of the aPDT and LLLT on wound healing, pain intensity, swelling, halitosis and postoperative usage of analgesics after surgical removal of the lower third molars. Background data: aPDT and LLLT reduces postoperative discomforts and the use of analgesics after surgical removal of third molars. Methods: The model group consisted of 150 healthy patients with the absolute indications for removal of lower third molars. Patients were randomly divided into three groups, 50 per each group. The first group received aPDT, second group LLLT and the third was indicated as a control group. The radiation power in aPDT group was 50 mW and the wavelength was 660 nm, while the power in LLLT group was 90 mW and the wavelength was 660 nm. Postoperative visits were scheduled on the third and seventh day when the patients from laser groups, were treated following the same protocol on the day of the surgery. Statistical analysis was performed using χ2 square, the independent Student’s t-test and one-way analysis of variance. Results: The results of the evaluation of the wound healing showed that there was a statistically significant difference in the all postoperative discomforts and taking analgesics between three patients groups (p<0.001). The patients that were subject to aPDT had the least expressed postoperative problems considering all three groups. Conclusion: Both used modalities of laser therapy statistically significant reduce postoperative problems after the surgical removal of third lower molars
