Antibiotic prophylaxis in third molar surgery: a review.

Area of Science:

• Oral and Maxillofacial Surgery
• Evidence-Based Dentistry
• Pharmacology

Background:

• The effectiveness of antibiotic prophylaxis in preventing complications following lower third molar surgery remains a subject of debate.
• Clinical guidelines often recommend prophylactic antibiotics, but robust evidence is lacking.

Purpose of the Study:

• To systematically review clinical trials assessing the efficacy of antibiotic prophylaxis versus placebo or no treatment in preventing infections after lower third molar surgery.
• To inform evidence-based recommendations for clinical practice.

Main Methods:

• A comprehensive literature search was conducted across Embase, Cochrane, and Ovid Medline databases (1966-January 2011).
• References from retrieved articles and review papers were also screened.
• Twenty-three eligible studies were identified and independently reviewed using two quality assessment scales.

Main Results:

• The review identified 23 studies, categorized as 15 "low-quality" and 8 "high-quality" based on assessment scales.
• Significant heterogeneity was observed in treatment modalities and study designs across the included trials.

Conclusions:

• There is currently limited scientific evidence to support the routine use of commonly prescribed antibiotics for preventing complications after lower third molar removal.
• High-quality, well-reported randomized controlled trials are necessary to establish definitive conclusions on the efficacy of antibiotic prophylaxis, considering risk factors and clinical outcomes.
