Abstract
There are over 30 million people in the world with HIV
infection and, whilst the rate of new infections is slowing, this number
continues to grow. Although in Australia the overall prevalence of HIV
infection in adults aged 15-49 is officially estimated at only 0.2%,
representing less than 20,000 people living with HIV and AIDS, our
geographical area contains populations with prevalences exceeding 10 times
this. Oral health professionals must therefore practise safe, standard
infection control at all times and be aware of the oral manifestations of
HIV disease. These are predominantly opportunistic infections with fungi
such as Candida albicans or with viruses of the herpes family, particularly
herpes simplex, herpes zoster and Epstein-Barr virus infections. Warts or
papillomas may arise due to human papilloma viruses--even in individuals on
effective antiretroviral therapy. Rare types of fungal infection can occur,
and severe bacterial infections, notably tuberculosis, are an ever-present
risk. Susceptibility to periodontal breakdown is somewhat enhanced by the
effects of HIV disease itself, and caries activity may increase because the
patient neglects attention to diet and oral hygiene. Restorative and
periodontal care need, therefore, to be maintained at a high level. Oral
opportunistic infections cause much distress and the diagnosis and
management of these is the responsibility of our profession.
"Low-grade inflammation appeared to be playing a
role.....the risk of a fatal or nonfatal event was 40% greater for those who
brushed once rather than twice a day and 2.3-fold higher for those who
brushed less than once a day...." |
