A double blind clinical trial to assess the value of aprotinin in third molar surgery.
The bovine derived polypeptide, aprotinin, inhibits the activation of certain chemical mediators of acute inflammation. These mediators are responsible for causing pain and swelling in traumatised tissue. The properties of aprotinin were assessed in patients requiring surgical removal of third molars, a procedure which often results in considerable postoperative pain and swelling. A double blind clinical trial compared the effects of local infiltration of 1 ml of saline on one side of the mouth and aprotinin (10,000 international units) on the other, in patients requiring extraction of both mandibular third molars. Pain scores were assessed with a visual analogue scale, and swelling was subjectively assessed. The results, when analysed statistically, showed that aprotinin significantly reduced postoperative pain and swelling on the side of the mouth on which it was used, as compared to the control side (0.01% significance).
