Guideline to prevent surgical site infection was published from Japanese society of surgical site infection and Japanese society of antibiotics chemotherapy in 2016. In the guideline, antibiotics prophylactic regimen has described in the all field of surgeries including oral surgery and dentistry. In 2018, Japanese society of cardiology published revised version of ‘Prevention and treatment of infective endocarditis (IE)’. In the guideline, antibiotics prophylaxis of IE in dentistry has described extensively. Since proper use of antibiotics for prevention of antimicrobial resistant bacteria production in oral surgeries has not been discussed sufficiently, we oral surgeons should understand the importance of proper antibiotics prophylaxis in oral surgery in accordance with these new guidelines.
