title: Clinical effects of aspirin and acetaminophen on hemostasis after exodontics.
abstract: The effects of aspirin and acetaminophen on postextraction hemostasis were evaluated in a double-blind study in a group of 43 patients; 20 received aspirin and 23 received acetaminophen. No significant difference was found in the observed postsurgical alveolus bleeding times or the patients' reported length of postoperative bleeding. However, Ivy bleeding times taken after the ingestion of 80 grains of medication showed an elevation in 75% of the aspirin users and in 60% of the acetaminophen group; the mean change in bleeding times was 2.75 times greater in the aspirin group.
