NCT01060774

Brief Summary

This study is testing a local anesthetic (numbing medicine) to suppress pain. Bupivacaine and lidocaine are FDA approved local anesthetics that may decrease pain following surgery. Patients will receive either 2% lidocaine, 0.5% bupivacaine, or placebo with epinephrine 1:200,000 as a numbing medicine at the end of root canal surgery. Small pieces of gum will be taken before and after surgery and 2 days later to analyze chemicals that may be related to pain sensation.

Outcome Measures

Primary Outcomes (1)

  • Assess the local inflammatory response as measured by tissue expression of the prostanoid enzymes cyclooxygenase (COX-2) and other cytokines and inflammatory mediators.

    The difference in inflammatory gene expression between treatment groups.

    48 hours

Secondary Outcomes (1)

  • Evaluate the clinical outcome of postoperative pain following endodontic surgery, as measured by pain category and visual analog scale (VAS) and postoperative analgesic requirements.

    48 hours

Study Arms (2)

Bupivacaine

EXPERIMENTAL

0.5% bupivacaine/1:200,000 epinephrine

Drug: Bupivacaine

Lidocaine

EXPERIMENTAL

2% lidocaine/1:200,000 epinephrine

Drug: Lidocaine

Interventions

Up to 5 capsules of 2% lidocaine with epinephrine as a reinforcement drug post-operatively

Also known as: Xylocaine
Lidocaine

Up to 5 capsules of 0.5% Bupivacaine with epinephrine given post-operatively.

Also known as: Marcain, Marcaine, Sensorcaine and Vivacaine.
Bupivacaine

Eligibility Criteria

Age18 Years - 65 Years
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Male or female volunteers referred for endodontic surgery willing to undergo 2 visits: 1 surgical appointment, and 1 follow-up research-related appointment
  • Ages of 18 and older
  • Willing to undergo observation for 1/2 hour post-operatively
  • Willing to complete a 100 mm visual analog scale and record analgesic intake over 48 hrs period
  • Willing to have a preoperative and postoperative biopsy on the day of surgery
  • Willing to return at 48 hours post-operation to turn in completed pain diaries and for the third biopsy

You may not qualify if:

  • Allergy to or other contraindications to use of aspirin, sulfites, amide anesthetics, or acetaminophen
  • Chronic use of medications confounding the assessment of the inflammatory response or analgesia, for example, NSAIDS, COX-2 inhibitors, antihistamines, steroids, antidepressants
  • Medications contraindicated with bupivacaine: MAO inhibitors and anti-depressants
  • Diseases such as diabetes mellitus, liver disease, chronic infections, rheumatoid arthritis or any other systemic disease that compromises the immune system
  • Unusual surgical difficulty
