Introduction: The extraction of third molars is a frequent procedure in dental practice. To minimize postoperative infectious complications, the use of antibiotics has been routinely employed. However, there are reports in the literature of different ways to use this prescription drug, seeking to reduce the bacterial resistance index. Objective: The objective of this study was to evaluate the incidence of postopera- tive infection in three groups, by analyzing each prescription for third molar extractions patients. Methods: The 30 sub- jects were randomized into three groups of 10 patients each. The first practice consisted in using the systemic antibiotic only in the preoperative period (Amoxicillin 2g, 1 hour before the procedure). In the second, the systemic antibiotics were administered only postoperatively (Amoxicillin 500mg every 8 hours for 7 days). In the third group, there was no system- ic antibiotic prescription. Results: regarding the occurrence of infections, in this study, there was no statistically significant difference between the protocols. However, concerning the occurrence of pain, there was a difference between the protocols used. In group 3, more individuals reported pain, compared to G1 and G2 patients. Conclusion: It was observed that systemic antibiotic administration does not interfere with postoperative infectious events in third molar extraction.
