From bugs to Pyorrhea, notes on periodontal causation

Despite substantial development in access to oral hygiene devices, education on oral hygiene procedures and improvement in the levels of oral cleanliness in western populations, only relatively small changes in the distribution of periodontitis can be attributed to these improvements. What has been overlooked? This lecture will endeavor to address critically aspects of the current understanding of periodontitis as they relate to contemporary concepts of causal inference.



Wim Teughels

Professor at Catholic University Leuven (Belgium) with teaching responsibilities in the field of periodontal therapy and human anatomy and research focused on periodontology and oral microbiology with special attention to bacterial adhesion and microbial interactions.

Biofilm, there’s no smoke without a fire

Effective oral biofilm control is the cornerstone of any attempt to prevent and control periodontal diseases. Although oral biofilms have never been more exciting, the more we know about them, the less we understand. There are obvious advantages for the microbiota to live within a biofilm. However, although they are rigid structures to interfere with as a practitioner, biofilms are highly dynamic and the composition is determined by complex interactions from within the biofilm but also with the host. Currently, to be controlled, plaque must be removed frequently by mechanical and or chemical self-care methods. However, attempts are being made to control biofilms from a more biological point of view.

Editor-in-Chief of the International Journal of Dental Hygiene and has been President of the International Federation of Dental Hygienists and the Swedish Dental Hygienists Association.

Actions speak louder than words

The presentation will cover an scientifically evidenced individually tailored oral health education programme based on cognitive behavioral theory technics performed by dental hygienists. The model has resulted in reduced gingivitis interproximally, reduced plaque and increased use of inter-proximal cleaning aids. In addition the patients reported an improved oral health-related quality of life after dental hygiene treatmen. The health-economic evaluation showed that the incremental costs of the cognitive behavioral treatment can be considered as low and strengthens the suggestion that an individually tailored oral health educational programme integrated in non-surgical periodontal treatment is preferable to a standardised education programme.



Peter Robinson

Professor of Public Health and Director of Research of the School of Clinical Dentistry, University of Sheffield. In a previous life he was proud to be Director of the School's Programme in Dental Hygiene and Therapy.

Toothbrushing, is perfect possible?

The lecture will deal with the updated Cochrane review but also reflect on other recently published systematic and meta-reviews. To consider why the effectiveness of toothbrushing is important and what are the potential harms. This evidence will be applied to strategies to improve the health of individual patients and the population at large

Professor, Chair and Director of the Department for Conservative Dentistry and its clinic in the Center for Oral Diseases, School of Oral Medicine, Christian-Albrechts-University / University Hospital of Schleswig-Holstein in Kiel, Germany.

Interdental cleaning, easier said than done

Good interdental oral hygiene requires a device that can penetrate between adjacent teeth. The choice must be made in relation to the characteristics of the interdental spaces and whether or not they are accessible for the particular device by the respective patient. Over the last two decades more and more systematic reviews have been published in relation to various interdental oral hygiene devices. Systematic reviews provide a synthesis that embraces rigorously all primary research evidence, a meta-review summarizes the findings and implications of these systematic reviews. Recently a meta-review on interdental oral hygiene devices was performed and the results will be presented.

Antimicrobials, cross your t’s and dot your i’s

Chemical plaque control might be necessary in those subjects who are not capable of properly controlling supragingival biofilms using conventional mechanical procedures. The use of chemical formulations (especially antiseptics) to control levels of plaque and gingivitis has been widely evaluated. The efficacy of different formulations has been reported in several systematic reviews. There is weak but consistent evidence that the adjunctive use (to mechanical plaque control) of dentifrices, mouthrinses or the combination of both, containing specific agents for gingivitis and/ or plaque control, provide statistically significant improvements in terms of gingival, bleeding and plaque indices.
