Study summary

Despite over 50 years of antibiotic use and multiple clinical investigations (>50), no definitive studies exist to confirm or refute the use of systemic antibiotics to prevent postoperative inflammatory complications after third molar (M3), aka "wisdom teeth" removal. Among patients having M3s extracted, does the administration of systemic prophylactic antibiotics when compared to placebo, decrease the rate of postoperative inflammatory complications? The first specific aim of the study is to implement a randomized, placebo-controlled clinical trial to determine if systemic prophylactic antibiotics, when compared to placebo, decrease the rate of postoperative alveolar osteitis (AO) after M3 extraction. For this proposal, postoperative AO is the primary outcome variable.

The second specific aim is to implement a pilot study using a randomized, placebo-controlled clinical trial to determine if systemic prophylactic antibiotics, when compared to placebo, decrease the rate of postoperative infection after M3 extraction. For the purposes of this proposal, postoperative infection is a secondary outcome variable. Based on sample size estimates, we believe it will be necessary to implement a multi-year trial to address the second specific aim definitively. As such, we will use the experience and preliminary results derived from this clinical trial to develop and implement a future large scale clinical trial.

The third specific aim is to identify risk factors associated with postoperative inflammatory complications in order to develop a model to predict if the prophylactic administration of antibiotics will prevent the postoperative inflammatory complications of alveolar osteitis and infection following the removal of M3's.

The long-term goal of this project is to provide compelling clinical evidence to support recommendations regarding the use of systemic antibiotics in this setting and alter clinical practice based on the results of a well-done, definitive clinical investigation.

Read the detailed description

The management of impacted M3s is a high volume procedure. In the United States, the cost of M3 removal has been estimated to be over 2 billion dollars, not including costs for consults, x-rays, medications, surgical center charges, or over 5 million surgical extractions and treatment of postoperative inflammatory complications (Flick. 1999). Practices associated with M3 removal can have a significant impact on large numbers of patients, providers, and payers. There is currently no consensus on the use of systemic antibiotic prophylaxis to decrease the risk of inflammatory complications following M3 removal.The most common post-operative inflammatory complications following M3 extraction are alveolar osteitis (AO) and wound infection (Larsen, 1992; Piecuch et al., 1995; Sekar et al., 2001). AO, aka "dry socket," is a wound-healing problem characterized by severe, unremitting pain. The reported frequency of AO is 6-68%. Bacterial colonization stimulates plasmin production and fibrinolysis with dissolution of the extraction site clot . More than 45% of patients who sustain AO require 4 or 5 more postoperative appointments for resolution of symptoms (Larsen, 1992; Andra et al., 1990). Given its common occurrence, identifying treatments, i.e. systemic antibiotics, to decrease the rate of AO following M3 extraction would be an important contribution to enhancing patient outcomes. The second common postoperative inflammatory condition following M3 extraction is wound infection. The reported frequency of postoperative infection ranges from 1.2 - 27%, with most studies reporting a frequency of \<10%. Because wound infections are bacterial, it is hypothesized that using systemic antibiotics will reduce the rate of postoperative wound infections. There are, however, no definitive prospective studies that support or refute the necessity of systemic antibiotics in the prevention of postoperative inflammatory complications of AO or infection.

All studies published to date addressing the role of systemic antibiotics and M3 removal have one or more major methodological flaws in study design characterized as :1) no or ambiguous definition of the outcome variable, 2) inadequate sample size, 3) non-uniformity of protocol design, 4) lack of randomization techniques and 5) poor-follow-up monitoring. Clearly, there is a need for a definitive, rigorous, well-designed placebo-controlled randomized clinical trial to ascertain the efficacy of systemic antibiotics in preventing postoperative inflammatory complications after M3 removal.

Inclusion criteria

  • Demographics: While all ages are eligible for study enrollment, as a practical matter, most patients having M3s removed are usually > 13-14 years of age.
  • Gender: Males and females will be offered to participate in this study.
  • Race: All races and ethnicities are eligible for study enrollment.
  • Clinical status: at least one impacted mandibular third molar ( M3 ) must be scheduled for extraction.
  • Anesthesia: Patient request that the procedure be executed using intravenous sedation or general anesthesia. Intravenous sedation will be accomplished with use of an IV placed in the antecubital fossa of each patient
  • Health status: Healthy patients or patients with mild systemic disease, i.e. ASA status \< 3, are eligible for study enrollment.

Exclusion criteria

Exclusion Criteria:

  • Pre-existing infection: Infection is characterised as having an area with frank purulence and/or cellulitis characterized by erythema, induration and inability to open the mouth wide enough to provide access to the airway.
  • Pre-existing Systemic Illness: as evidenced by severe dry mouth, patients who have undergone radiotherapy for oral cancer, patients that are , patients that require antibiotic prophylaxis for endocarditis, as well as, patients who are taking antimicrobials for other systemic diseases, i.e., uncontrolled diabetes., ASA status > 2.
  • Allergic Reactions to Medications: Patients who are allergic to Penicillin and Clindamycin will be excluded from the study.
  • Anesthesia: Patient request that the operation be performed with local anesthesia without intravenous sedation or general anesthesia.
  • Pregnancy: Pregnancy is a relative for study enrollment. If after consultation with the obstetrician, there is no contraindication to removing the impacted teeth with sedation or contraindication to receiving the test medications (penicillin or clindamycin) and the patient wants to pursue treatment, she would be considered eligible for study enrollment.
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jul 16, 2010, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
