I finally got in touch with my daughter to ask questions on Hep c and
treatment.  She stated that most people are not aware they have Hep or
any other communicable disease.  It is a courtesy to let the Dr. know
but not necessary.  In some instances by letting the Dr. know treatment
could be different for the patients health.  The dentists are trained
to take proper precautions with ALL patients.  She runs tests on her
equipment and the test strips are sent to the local university to make
sure that all of her equipment is properly sterilized.  Dentist may not
charge anything more than what they charge non hep clients.  To do so
is opening themselves to a discrimination law suit.  Refusing treatment
is a no no as well and you can sue.  This is true in Canada and the
USA.
