Infective endocarditis is a desease caused by microbial infection of the demaged heart valves or endocardium. Transient bacteremia after dental treatment most often result in infective endocarditis. We report a case of infective endocarditis caused by dental treatment. The patient was a-45-year-old man. He was pointed out hypertention and mitral valve regurgitation. After endodontic treatment of his left lower first maler at his home dentist, he began to feel low grade fever and general fatigue. His blood data showed infection and echocardiography revealed a vegatation of his mitral valve. These findings were suspected infective endocarditis, he was hospitalized emergency. γ-hemolytic streptococcus was detected cultivating bacteria of his blood. He was treated antibiotics therapy about two months. We performed extraction and root canal treatment simultaneously. The symptons were free, he was discharged succcessfully. We must take providing prophylactic antibiotics to prevent endocarditis for patients with congenital or acquired cardiovascular defect.
