Abstract

Third molar extractions in general anesthesia have become a standard procedure in dentistry. There is an effort to shorten healing time and decrease the number of complications as well as increase comfort after the treatment. Low-level lasers are known for their analgesic, anti-inflammatory, and stimulatory effect. The aim of the study is to evaluate the effect of low-level laser after surgery in general anesthesia reducing the patient's discomfort, i.e. mainly pain, and also, to monitor the biostimulation process. Our study included 79 patients treated at the Department of Maxilofacial Surgery, diagnosed with third molar retention. Diode low-level laser radiation (wavelength 830 nm, output power 270 mW, probe aperture of 6.4 mm²) with dose ~ 3 mJ was applied. The control group was treated by using placebo - red light. The exposure time was 11 seconds immediately after the suture; the treatment was repeated every day for the following 3 days. To evaluate the effect of laser biostimulation, the objective markers for immunological determination of healing - sIgA and lysozyme in non-stimulated saliva of patients - were used. The sIgA decreases after laser application from 546.91 mg/l to 304. 91mg/l and in the control group from 602.25mg/l to 425.62 mg/l. The results were statistically significant. The level of lysozyme decreases from 54.27 mg/l to 2.45mg/l after laser biostimulation, from 304.371mg/l to 11.08mg/l after placebo effect. The study has confirmed a low-level laser healing effect not directly related to pain.
