Dr. Denis Kinane Presents Basis and Consequences of Periodontal Disease Susceptibility

COURSE DESCRIPTION This talk will begin by addressing the host responses to the microbial biofilm in periodontitis and peri-implantitis and discuss variable susceptibility to the subgingival dental plaque. The host response to infection draws upon the innate, inflammatory and adaptive immune systems, whose role is to provide the appropriate response to the offending microorganisms. In some cases, this will be little or no response when encountering ‘commensals’, and in other cases a gradated response depending very much on the host’s own determination of the pathogenic nature of the microbial insult: and herein lies the root of variation in host responses that govern individual susceptibility. In some individuals and with some bacteria this will be an innate- only response, others will need to invoke the inflammatory response, and yet others will require the adaptive immune response – be it cellular, humoral or both – to reduce or remove the challenge from the microbes. Of course these responses would be somewhat easier to predict with a single pathogen challenge, and become infinitely more complex as the biofilm increases in complexity. Oral infections, in particular

1 gingival inflammation, originate from not just one but many bacterial species. This polymicrobial infection may result in chronic inflammation in some subjects but not in others due to genetic variation among humans. In addition. the local chronic inflammatory lesions around teeth and implants may have systemic impact and thus therapy for oral diseases is considered to have beneficial effects on general or systemic health. The causes of variation in host response, biofilms and their effect on general health such as diabetes and cardiovascular disease will be discussed.

Denis F. Kinane, BDS, PhD, FDS RCS (Edin), FDS RCPS (Glas) is currently the Dean of the University of Pennsylvania School of Dental Medicine, and of and Periodontics. His many academic qualifications include serving as Associate Dean of Research at the Dental School, holding membership of both the Royal College of Surgeons of and Glasgow and he currently maintains NIH funding for research in periodontal disease susceptibility. Dr. Kinane is widely publicized in international peer- reviewed journals, serves on editorial boards and is a highly sought after international speaker.
