PROTECTION BARRIERS INTRODUCTION Biosafety standards are intended to reduce the risk of transmissionof microorganisms from recognized and unrecognized infection inHealth Services accidents linked to exposure to blood and bodyfluids
OBJECTIVES1.The accidentprevention Both Dental Surgeons, Health staff andmeasures of patients are those most at risk of contracting infectious diseases such ashealth personnel AIDS, hepatitis B, tuberculosis, herpesis exposed to virus hominis infections.blood and otherbiological fluids. 2.La conduct tobe followed in anaccident withexposure to theseelements

CONCLUSIONS• Biosecurity and its rules must be respected by all for the sake of protecting their patients, their partners and their own health, so as to interrupt the chain of transmission of infectious agent and the disease itself.• The challenge of dentistry today is among others to define a working system, equipment and methods that allow you to increase coverage and maintain the necessary and appropriate aseptic.
