Abstract

Introduction: Surgical removal of an impacted third molar often involves postoperative complication such as swelling, edema, pain and trismus. Low-level laser the therapy is the application of laser irradiation to begin a photo chemical, non-thermal process without visible changes in tissue. The aim of this study was to evaluate the effect of low level laser on trismus and tissue healing after third molar surgery.

Material and method: Twenty patients with two similar and symmetrical impacted mandibular wisdom teeth were selected. 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 after surgery. In the experimental group, diode laser irradiated with 810 nm wavelength and 3J intrasocket and 5J buccally and on the other side as control group pretended to irradiate the socket but with no actual irradiation. Trismus and surgical site healing in the 7th day were evaluated. The results of this study were analyzed by Paired sample T-test and Wilcoxon rank test.

Results: Post surgical trismus were significantly less in laser group(P-value=0/0001) and also surgical site healing was significantly better in laser group. (P-value=0/008)

Conclusion: It can be concluded that the laser with the applied parameters in this study was successful in reducing post surgical side effects.
