Serratia infection in a patient with bilateral subcondylar impacted third molars and associated dentigerous cysts: report of case.

A case of bilateral subcondylar impacted mandibular third molars is presented. Both impactions had associated dentigerous cyst, one of which was severely infected with Serratia marcescens and had a draining sinus tract. The patient also had uncontrolled diabetes mellitus and iron deficiency anemia, which altered her response to surgical treatment. This case illustrates the necessity for early identification of infective organisms and determining their antibiotic sensitivity, as well as the need for prophylactic removal of impacted teeth to prevent complications such as those presented.
