Mark Cannon,


Dr. Mark L. Cannon is a Professor of Otolaryngology, Division of Dentistry at Northwestern University, Feinberg School of Medicine, an Attending Physician at Ann and Robert Lurie Children’s Hospital, and a member of the International Association of Pediatric Dentistry. In addition to being the founder of Associated Dental Specialists of Long Grove (1981), he is the Research Coordinator of the Pediatric Dental residency program at Ann and Robert Lurie Children’s Hospital, Chicago, Illinois. Dr. Cannon has 40 years of experience in pediatric dentistry and has presented lectures both nationally and internationally. Dr. Cannon has presented guest lectures at the University of Athens, Greece, Sao Paulista State University, UNESP, Aracatuba, Brazil, University of Texas- Houston, University of Alabama-Birmingham, University of Michigan Ann Arbor, Yonsei University, Beijing Medical University, CES (Medellin, Colombia) and at the University of Illinois, Chicago, Department of Pediatric Dentistry. He has had presentations to the following organizations; I.A.D.R./A.A.D.R., the American Academy of Pediatric Dentistry, the American Society of Dentistry for Children, Academy of Dental Materials, World Congress of Biological Materials, International Association of Pediatric Dentistry, Pediatric Dental Association of Asia, Australasian Academy of Pediatric Dentistry, World Congress of Preventive Dentistry, Mexican Association of Pediatric Dentistry, and the European Association of Pediatric Dentistry. He lectures on many oral health topics including evolutionary oral medicine, the gateway microbiomes, biologic and bioactive dental materials (patents owner), probiotics, and all aspects of everyday Pediatric oral health. Dr. Cannon has humbly accepted two invitations by the Karolinska Institute, first to the Nobel Forum (2016) and secondly to the Nobel Assembly (2017).

Is Tropism Dead?

Day One: Friday, September 30, 2022 | 10:00 AM - 10:30 AM MT

Tropism- is it still relevant? Infection specificity still exists but will pathogen infections only affect particular hosts and/or tissues? Theoretically, humankind and our microbiome co-evolve; so, many things change as our environment and diet changes. Strain shifts and lateral gene transfer (HGT) may change more than that one species. One particular pathogen, or on the other hand, one particular probiotic may dramatically alter a microbiome or specific biofilm. In addition, the changes in the hologenome seem to be the ongoing driver for evolution.

There was a common ancestor to both bacteria and viruses- viruses became simpler and bacteria more complex- and that started 3.5 billion years ago. We now have 39 trillion microbial guests living on us and in us, making us a huge cruise boat, with a substantial list of passengers (commensals), unruly passengers (pathobionts), probiotics (crew), and an occasional pathogen (pirate).

Amongst the pathogens is a “keystone” bacteria species that has become the ultimate guerrilla, capable of sabotaging our immune defenses and even hijacking our own cells for their protection and proliferation. These “keystone” pathogens are particularly virulent when they involve one of the ”Gateway” microbiomes. The oral microbiome is perhaps the most important “Gateway” microbiome and is now linked to the gut microbiome, faulty blood brain barrier, compromised immune functions and ultimately, the skin microbiome.
