[Clinical investigations on influence of radiation of venous blood with ultraviolet light on wound healing and postoperative complaints].

In 28 patients we performed lower third molar surgery with one following exposition of 50 ml venous blood to ultraviolet light. In 25 other accidentally selected patients we made the same operative procedure with only feigned expodition to ultraviolet rays. After real uv-treatment patients reported significantly less postoperative trouble (pain, swelling, analgetics) than in the control group. Therefore we discuss complex effects of ultraviolet light on wound healing.
