RESUMO
Odontogenic infections are associated with a variety of microorganisms. antibiotics are commonly used for the management of various dental infections and have a proven role in decreasing morbidity and mortality caused by infectious diseases. the frequent and over usage of antibiotics has been associated with a number of consequences such as the selection of drug resistant strains, and the formation of antibiomas. antibiomas are characterized by the formation of a localized pathology surrounded by thick fibrous tissues in response to long term antibiotics use. an established antibioma is characterized by a tough fibrous swelling accompanied by painful or painless swelling, intermittent fever and constitutional symptoms. in this article, we are reporting the case of a facial antibioma formed due to prolonged use of antibiotics prescribed for a residual periapical infection following endodontic treatment. in addition, the association of using antibiotics in this context is discussed.
