Cytokine Responses to Acute Inflammation in the Oral Surgery Model
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
This study will measure levels of an enzyme called cyclooxygenase in gum tissue following third molar (wisdom tooth) extraction. Cyclooxygenase is thought to contribute to pain that normally follows tissue injury or surgery. Healthy volunteers between 16 and 35 years of age who require removal of their third molars may be eligible for this study. Participants will receive an injection of a local anesthetic (lidocaine) in the mouth and a sedative (midazolam) through an arm vein before surgery. Before the tooth is removed, a small tissue sample (biopsy) will be collected from the gum tissue covering one of the lower third molars to be extracted. After surgery, a second biopsy will be taken at some point between just after surgery to the time when pain from the extraction starts to develop. These tissue samples will be analyzed for cyclooxygenase levels. Patients will stay in the clinic for up to 4 hours after surgery while the anesthetic wears off. During this time, they will complete pain questionnaires. If needed, patients may receive additional medicine for pain relief at any time during the surgery or the 4-hour observation period. They will also be given standard pain medication to take home at the end of the study.
