The most common of all the herpetic HSV-1
lesions is herpes labialis. They frequently involve the
lips and adjacent skin at the corners of the mouth.
Recurrence usually starts at the same location, starting
with a burning, tingling sensation and then forming
vesicles that fuse together leaving large lesions. After
the vesicles rupture, crusting of the surface occurs.
These lesions are known as fever blisters. The
crusted lesions are also referred to as cold sores,
because a common cold sometimes accompanies these
HSV-1 lesions. Known causes for the reoccurrence of
the HSV-1 lesions are:
threat to all dental health professionals and other
healthcare workers who are exposed to patients who
carry the virus.
Healthcare workers can be exposed to the AIDS
virus through contaminated body fluids, exposure to
blood or blood products, instruments, and equipment.
You should also know some of the oral manifestations
that infected people may have. Some of them are the
initial signs a dentist can use to diagnosis patients who
are carriers of the virus, but who have not been tested or
diagnosed. Some of the more common oral
manifestations of HIV infection are as follows:
Dental treatment (local trauma)
Stress or anxiety
The recurrent HSV-1 lesions usually take about 7
to 10 days to resolve. Any routine dental treatment is
recommended to be rescheduled during the active
phase of these lesions because the disease is highly
AIDS Virus (HIV Infection)
The human immunodeficiency virus type 1
(HIV-l) is the main cause of the acquired
immunodeficiency syndrome (AIDS). It is a
worldwide epidemic. This deadly disease is a direct
Candidiasis(fig. 5-13) a fungal infection of
the mouth, usually red or white in color
Hairy leukoplakia(fig. 5-14) a viral infection,
whose lesions appear as white, slightly raised, on
Kaposi's sarcoma(fig. 5-15) cancerous, dark
bluish-purple lesions that involve blood vessels
Procedures and precautions for protection will be
discussed in chapter 10, Infection Control.
Forms of oral cancer are found in the oral cavity at
any site, but most often in the tongue, floor of the
mouth, and the lower lip. The cancer is a neoplasm
