[The maxillofacial surgeon faced with the HIV-positive patient: risks and prevention].

Prevention against the transmission of the HIV must be universal today, which means that it applies to all patients. Blood, tissues, the CSF are infected, but nasal secreta, tears and saliva are not contaminated unless they contain blood. The statistical risk of an HIV serological conversion when making an injection is an estimate of 0.1 to 0.3%, one hundred times less than with the hepatitis B virus. The best protection for maxillofacial surgeons, who are very exposed by the manipulation of objects (needle, wires) and by considerable projections of blood (rotary motor) is not a systematic HIV serological test for all patients, but goggles with side screens, a double pair of gloves and the use of an antiseptic acting on the HIV in case of staining.
