An Introduction To Photodynamic Medicine

“There are two kinds of light — the glow that illumines, and the glare that obscures”

The Periowave light diffusing tip delivers light to the treatment area, powering the photodynamic reaction without heat or generating resista

James Thurber was almost certainly unaware of photodynamic medicine when he authored that quote in 1963, or else he might have added a 3rd type of light – the glimmer that heals. Loosely put, the word photodynamic means using light to cause an action or effect.  This definition, though simple, succinctly summarizes the concept of photodynamic medicine – a set of therapies that leverages visible light to create a targeted, potent effect. So how can simple light in the range of red to violet (the kind we can see) generate a clinical effect?  Save for a select group of therapies, some more reputable than others, it cannot…on its own.

The Case For Photodisinfection

Humans are multicellular creatures each comprised of trillions of cells. Oddly enough, bacteria in our bodies outnumber our human cells by 10:1, although their size is, on average, about one tenth of a human cell. When seen in this light, humans really are part human and part bacteria.  We are dependent on the maintenance of a delicate balance between human cells and bacterial cells for good health as we coexist with bacteria in a symbiotic relationship. There are estimated to be between 500-1,000 species of bacteria living in the human gut and skin.  Some of our bacteria are known to perform certain tasks that are critical. Without our bacteria, for instance, we would be unable to digest and process our food intake.  These commensal bacteria are widely known as our “flora”. Too many of any one kind of bacteria, and we are left in poor health. Bacteria, therefore, play a very important role in human health and human disease. Read More

The Passion Behind Periowave™

People have often asked me why I have been so passionate about Periowave™.  My commitment and dedication to this first application of Photodisinfection is borne out of a number of reasons. The first is my intense belief that the world is in desperate need of alternatives to antibiotics, especially in the cases of topical biofilm infections which are not adequately addressed by a systemic drug therapy.

Having worked with Photodisinfection for over a decade, I am convinced that better patient outcomes for gum disease are possible with the Periowave™ Photodisinfection System. Bacteria involved with gum disease hide in pockets between the tooth and the gums as biofilm, making these sites in the mouth more difficult to treat. Read More
