Pain development and consumption of analgesics after oral surgery in relation to personality characteristics.

In the present study a survey has been performed of the pain development and analgesic intake in 100 patients following elective oral surgery of impacted third molars in relation to preoperative assessment of personality characteristics. Our results show that no sex differences existed preoperatively concerning personality characteristics, concerning postoperative pain development or analgesic consumption. Fourteen patients reported no pain at all and 40 patients did not use any analgesics in the postoperative period. We also found a good correlation between total sum of pain scores and analgesic intake. Patients undergoing surgery in the morning reported a lower total sum of pain scores, reported pain at fewer occasions and tended to require less analgesics than patients being subjected to surgery in the afternoon. The patients who reported a total sum of pain scores in the upper percentile during the postoperative period rated their general health worse, as rated on the General Health (GH) questionnaire, and used more analgesics than did patients in the lower percentile. Also, patients not using any analgesics reported less symptoms of distress according to the GH scale as compared to patients using analgesics. In general, however, less than 10% of the variance in postoperative pain and consumption of analgesics could be explained by the preoperative factors studied.
