Blood exposure accidents

An AES is defined as any contact with blood or a biological liquid containing blood and involving either a skin invasion (puncture or cut) or a projection onto a mucous membrane (eye mouth) or injured skin (claw eczema wound)In dentistry but also in other health care services and laboratories the risk of AES is omnipresent. This risk is linked to the care procedures performed in these facilities. The infectious agents mainly involved in AES are: hepatitis B and C viruses as well as the human immunodeficiency virus. The purpose of our work is to evaluate the knowledge of the care personnel in dentistry concerning the process of prevention and management of the AES. We will begin with a reminder of the contaminating agents in dental practice. Then we will address the occupational infections transmitted after an AES and we will evaluate the risk of seroconversion in the professional environmentFinally we will study the means available to us to prevent blood-borne infections as well as what to do following an AES.
