In a group of 66 patients treated for difficult dentition of the lower wisdom tooth, 33 were subjected to biostimulative laser therapy. In this group 20 persons were treated conservatively together with laser therapy and 13 underwent surgical treatment together with exposure to laser irradiation. During the treatment a positive influence of the laser was found, i.e. a decrease in pain, edema, and trismus.
