Is post-operative antibiotic therapy justified for surgical removal of mandibular third molar? A comparative study

Surgical removal of impacted mandibular third molar (SRIMTM) is the most common procedure performed in oral and maxillofacial surgery. In the literature, many complications associated with lower third molar removal are described such as pain, swelling, trismus, infection, inflammation, and nerve damage. Antibiotics are routinely used either pre-operatively or post-operatively to reduce the chances of surgical site infection (SSI). However routine use of antibiotics for SRIMTM is still controversial. For antibiotics to be effective in reducing post-operative infective complications, the time of administration is very important. Adequate serum concentration of antibiotic must be achieved prior to the procedure. In a developing country like India, antibiotics are routinely prescribed post-operatively. The current study is designed to evaluate the efficacy of post-operative prophylactic antibiotic in SRIMTM.
