Rofecoxib to Prevent Pain After Third Molar (Wisdom Tooth) Extraction

• Status: Completed
• Trial end date: 2003-11-01
• Target enrollment: 0
• Participant gender: All

Summary

This study will evaluate the ability of a new non-steroidal anti-inflammatory drug (NSAID) called rofecoxib to prevent pain following third molar (wisdom tooth) extraction. The Food and Drug Administration approved rofecoxib in 1999 to treat the symptoms of arthritis, menstrual cramps, and pain.

Healthy normal volunteers between 16 and 35 years of age in general good health who require third molar (wisdom tooth) extraction may be eligible for this study. Candidates will be screened with a medical history and oral examination, including dental x-rays as needed to confirm the need for third molar removal.

Participants will have all four wisdom teeth extracted, and a biopsy (removal of a small piece of tissue) will be taken from the inside of the cheek around the area behind the lower wisdom tooth. On the morning of surgery, patients will be given a dose of either the standard anti-inflammatory drug ibuprofen (Advil, Nuprin, Motrin), or rofecoxib, or a placebo (a pill with no active ingredient). Before surgery, they will be given a local anesthetic (lidocaine) in the mouth and a sedative (midazolam) through an arm vein.

After the surgery, patients will remain in the clinic for up to 4 hours to monitor pain and the effects of the drug. Patients will complete pain questionnaires. Patients whose pain is unrelieved an hour after surgery may request and receive morphine intravenously (through a vein). After 4 hours, patients will be discharged with additional pain medicines (Tylenol with codeine and the study drug) and instructions for their use. They will also be given a pain diary to record pain ratings and medications taken at home. A clinic staff member will telephone patients at home the morning after surgery to ensure they are rating their pain intensity at the proper time and are taking their medications as instructed.

Patients will return to the clinic 48 hours after surgery with the pain diary and pain relievers. At this visit, another biopsy will be taken under local anesthetic.

Criteria

INCLUSION CRITERIA

Male or female volunteers referred for third molar extraction willing to undergo 3 visits:

1 screening visit, 1 surgical appointment, and 1 follow-up research-related appointment.

Between the ages of 16 to 35 years (based upon eruption patterns and age-related complications associated with surgical extraction of third molars)

In general good health- American Society of Anesthesiologists (ASA) status I or II (healthy subjects based upon criteria for safe administration of out-patient conscious sedation)

Willing to undergo observation period for four hours post-operatively

Willing to complete a 100 mm visual analog scale and a category scale every hour for the first 4 post-operative hours, and again at 24 and 48 hours

Willing to have a preoperative biopsy on the day of surgery and a postoperative biopsy at 48 hours

Willing to return 48 hours to return completed pain diaries and for the postoperative biopsy

Sum total of the assessment of surgical difficulty ratings (Screening visit) must be between 8 to 14 in order to evaluate subjects experiencing similar pain levels.

EXCLUSION CRITERIA
