The Use of Antibiotics in Odontogenic Infections: What Is the Best Choice? A Systematic Review.

PURPOSE

Odontogenic infections are a common problem in dentistry, and their treatment often requires the use of antibiotics besides the removal of the source of infection, which frequently makes it more difficult for clinicians to make a decision regarding the choice of antibiotic. This study aimed to answer the following questions through the Patient, Intervention, Comparison, Outcome (PICO) format: When should antibiotics be used in dental infections (DIs)? Which are the most effective drugs? How long should antibiotics be administered?

MATERIALS AND METHODS

This was a systematic review using the PubMed, Scopus, and Cochrane databases without restriction as to the period researched. The variables analyzed in each article were the number of odontogenic infections in each study, type of study, surgical intervention performed, antibiotics administered, statistical differences between groups studied, and patients' evolution after treatment.

RESULTS

The search included 1,109 articles. After the full reading of 46 articles, 16 were included in the final review and 30 were excluded. A sample of 2,197 DI cases was obtained, in which 15 different antibiotics were used, with a 98.2% overall cure rate.

CONCLUSIONS

The studies showed that antibiotics were prescribed only in situations of regional and/or systemic body manifestations. In the case of DIs, once drainage has been performed and/or the cause of infection has been removed, all antibiotics tested are equally effective with respect to clinical cure, and the choice of antibiotics is not as successful as the local intervention treatment procedure. When the real need for antibiotic therapy is detected, antibiotics should be used for the shortest time possible until the patient's clinical cure is achieved.
