In a placebo controlled double-blind randomized study the effect of low level laser therapy on postoperative complaints after removal of lower third molars was examined. Several parameters were investigated in two groups of patients; in one group low level laser was applied during and following third molar removal, in the other no active additional laser treatment was given. The results of this study show that therapeutic low level laser treatment could not statistically reduce the postoperative pain, swelling, trismus and function impairment after extraction of lower third molars.</p
