Infection from an exfoliating primary tooth in a child with severe neutropenia: a case report

In patients with deficient immune defenses, a localized oral infection can progress to a systemic infection. The purpose of this paper was to describe the case of a child with acute lymphoblastic leukemia who presented with fever, trismus, and submandibular swelling in the absence of the typical dental causes of infection such as deep dental caries or clinically significant periodontal disease. Treatment included an aggressive intravenous antibiotic regimen and extraction of the offending tooth after the recovery from bone marrow suppression.
