One of the most complex and perplexing problems in dentistry today is infection control. The oral cavity is a sea of microorganisms normally living in balance with the entire human body. Under certain conditions pathogenic or “disease causing” microorganisms can become the dominant life forms, this creating what we call infection. These pathogenic microorganisims live together in what is called a biofilm. This biofilm supports a mixed type infection made up of bacteria, viruses, fungi and even parasites. The difficulty is that each of these “disease causing” types needs a different drug to eliminate its dominance. What if we had an agent that could treat and eliminate the infection and, in addition, support the surrounding healthy tissue, without toxic side effects? We do now oxygen/ozone therapy for dentistry.
