Background. Research on the effects of low-level laser (LLL) radiation on living organisms has been conducted for nearly 40 years now, and the effectiveness of LLL has been examined in many diseases. The aim of the present study was to examine the impact of laser biostimulation on the restoration of the sense of touch after injury to the mandibular and maxillary regions, using a double-blind experiment. Material and methods. Our research involved 61 patients with fractures of the upper or lower jaw. The subjects were divided into two groups: Group I (31 persons) received laser therapy, while Group II (30 persons) received a placebo treatment. Touch sensation was tested by a JVP Domes esthesiometer, and the surface areas of disturbed sensation were measured.Results. After the observation period, the surface area of diminished sensation was reduced by an average of 9.52 cm2 in the laser group, and 5.03 cm2 in the placebo group. The difference is statistically significant. A comparison of touch sensitivity in the two groups showed less sensitivity in the placebo group. The results of a questionnaire suggest that laser biostimulation has a positive impact on the regeneration of the sense of touch in the face.Conclusions. Low-level laser radiation accelerates regeneration of the trigeminal nerve.
