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. And subsequently the major part of the presentation is on the clinical variance and the management principles of these Candida infections, and finally 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, for example, 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 carry yeast, 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 in particular. There are other sites of the human body where Candida resides. And these include the vaginal mucosa, the skin, and the large intestine.
