This talk is about soreness and ulcers
due to vesiculobullous disease.
And this is Dr. Nikolaos Nikitakis
from the University of Athens.
Today, we will talk about
and under this term
we can classify any disease
that may affect the oral mucosa
with a clinical presentation
of a vesicle or a bulla.
Both these terms
refer to a fluid-filled cavity
which is either small,
less than 5 millimeters,
this is a vesicle, or larger than
5 millimeter, and this is bulla.
In the oral mucosa these lesions
are the vesiculobullous lesions
are short-lived, in other words
they do not last long,
they rupture easily and as a result
what we will see most often
will be erosions or ulcers.
We may see impact blisters,
vesicles, or bullae,
or we may not see at all impacted blisters,
instead we see the result
of the breaking down,
which is the erosions and ulcers
that they leave behind.
The vesiculobullous diseases
affecting the oral mucosa
can be classified in various categories
according to their etiology and pathogenesis.
The main categories
are the immunologically-mediated diseases,
the hereditary diseases, the allergies,
and the infections.
For this presentation,
we will focus
on the immunologically-mediated diseases.
But let's briefly see
the other three categories.
