• 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.
