A 28-year-old male with infective endocarditis (I.E.) caused by odontogenic infection is reported. The patient was admitted to a hospital for the treatment of cerebral infarction. On admission, he had a heart murmur and vegetation of the mitral valve. He was referred to the cardiovascular division of the university hospital and consulted our division chiefly concerning I. E.
The clinical and radiographic examination showed a maxillary cyst, some apical periodontitis, some marginal periodontitis and multiple dental carious teeth. CRP value decreased gradually into the normal range after extraction of those teeth and a cystectomy. His infected mitral valve was successfully replaced with a prosthetic valve. The patient is now free from the symptoms with a good functional value.
