Human bites to the hand.

Human bites to the hand or penetrating injuries contaminated with saliva can be a source of aggressive infection and debilitating injury. These types of injuries may also be a mode for the transmission of disease, notably hepatitis B. Dental personnel have an increased risk of experiencing bite injuries and should understand the general principles of appropriate management. Staphylococcal or streptococcal species are often associated with infected bite injuries, and amoxicillin and clavulanate are currently advised for prophylaxis. Wound cleansing and careful monitoring, combined with appropriate prophylaxis, are the mainstays of treatment.
