Welcome to the presentation
on oral candidiasis.
My name is Lakshman Samaranayake
and I am an Emeritus Professor
at the University of Hong Kong,
where I was the Dean of the Faculty
of Dentistry for 10 years.
I have published more than 300 articles
on the subject of Candida infections
of the oral cavity.
After a brief preamble,
I'll be discussing
the predisposing factors
for oral Candida infections
and go on to
classification of candidiasis.
the major part of the presentation
is on the clinical variance
and the management principles
of these Candida infections,
we will end up the presentation
with diagnostic and laboratory aspects
of Candida infections.
Candida is an opportunistic
fungal pathogen of the oral cavity,
so called because it causes infection
when an opportunity arises,
when the immunity of the host wanes.
It is also the major fungal pathogen
in the oral microbiome.
It has been said that
the candidiasis or candidal infections
are seen in the very young,
the very old and the very sick.
It should be noted
that in the literature
there are two terms
candidiasis and candidosis,
which are synonymous
but in this presentation we shall use
the term candidiasis throughout.
Almost one half of the human population
particularly Candida in the oral cavity,
and the most common
residential site of the yeast
is on the dorsum of the tongue.
And if one is wearing a denture,
the fitting surface of the upper denture
There are other sites of the human body
where Candida resides.
And these include the vaginal mucosa,
the skin, and the large intestine.
