Position papers by EADPH special interest groups.

The board of the European Association for Dental Public Health (EADPH) is very grateful that two of the EADPH special interest groups were able to produce position papers in their fields within a relatively short time. Their first article, “Methodological issues in epidemiological studies of periodontitis – how can it be improved,” was prepared by Roos Leroy, Ken Eaton and Amir Savage following their discussions with the members of the special interest group on Periodontal Epidemiology at the 2008 and 2009 meetings of EADPH. The second article you will find in this issue. “Tooth wear and erosion: Methodological issues in epidemiological and public heath research and the future research agenda” was prepared by Carolina Ganss, Alice Young and Adrian Lussi. This paper is predominantly the result of work completed at the meetings of the Special Interest Group “Tooth Surface Loss and Erosion” at the 2008, 2009 and 2010 conferences of the EADPH. Working with the members of the group, the authors identified gaps in research strategies. Furthermore, they pointed out that fundamental concepts of wear and erosion as an oral health problem have not yet been sufficiently defined. This important paper draws the following main conclusions with regard to the research agenda: a consensus process towards an internationally accepted index on erosion and the collection of data on the various forms of wear on a population-based level should be initiated. In addition, communication between basic and clinical sciences and the area of Public Health Dentistry should be promoted in order to discuss, for example, whether tooth wear is a public health problem or not. The EADPH officer coordinating the special interest groups would like to use the publication of this paper as an occasion to present the respective EADPH activities to the readers of Community Dental Health. In September 2007 the General Assembly of EADPH, meeting in Ghent, accepted the proposal to initiate several special interest groups at the subsequent annual meeting of EADPH in Heidelberg. This proposal aimed to improve research and encourage activities in the area of Dental Public Health in Europe. Intensive discussion identified the following topics for development:
