Dens in dente associated with infective endocarditis.

This article describes an 11-year-old patient in whom infective endocarditis developed after the occurrence of a dental abscess associated with a dens in dente affecting the maxillary left lateral incisor. Dens in dente has not been reported in the literature previously as a source of infection associated with infective endocarditis. A prolonged period of hospitalization was required to control the infective endocarditis, which was caused by a strain of nutritionally deficient streptococci.
