ORCA activities and developments over the year 2016 (published as Editorial in Caries Research, 2017;51:I-II (DOI:10.1159/000457214)
The European Organization of Caries Research (ORCA), in support of it‘s missions, makes many efforts to increase activity and visibility of the organization, by organizing, in addition to the annual congresses, other scientific forums such as symposiums, summer schools and workshops, either within ORCA or jointly with other scientific associations. Amongst all the meetings held over the past year, the following two events could be mentioned as some of the most important endeavours to cover a broad spectrum of research pertaining to health promotion: the “Sugar” symposium, organized jointly with the European Association of Dental Public Health (EADPH), and the workshop “Boundaries between Dental Caries and Periodontal Diseases”, in partnership with the European Federation of Periodontology (EFP). The aim of those meetings was not only to stimulate research activities in prevention of dental and oral diseases but also to provide the ORCA members and attendees an opportunity to network with the international community of researchers while exploring the latest scientific discoveries in the field.

Another step in support of the ORCA missions was made by introducing several amendments in
the Constitution and Bylaws of ORCA. The proposed amendments were announced to the memberhsip in the newsletter, then discussed during the General Assembly on 7th of July, 2016, in Athens, Greece, and approved by the extraordinary General Assembly on 6th of November, 2016, in  La Granja de San Ildefonso, Spain. Thus, the amendment in the Constitution comprised introduction of the Institutional membership applicable to non-profit organizations, educational or research institutions engaged in caries research or oral health promotion, and interested in the activities of ORCA. In the Bylaws, the Individual membership category was modified by cancellation of the Introductory membership and maintaining the categories of Full, Retired and, Honorary members, as well as introduction of Student membership. The latter category is applicable to students currently enrolled for a degree at recognized academic institutions; without an academic appointment and interested in caries research. The annual membership fees for students shall be recommended by the Board and approved by the General Assembly.

Furthermore, application for the membership has been simplified so that recommendation letters are no longer required. Any individual eligible for membership under the Constitution and Bylaws can become a member of the organization. Full or Student Membership will be considered following submission of application and payment, and membership will become official following the review of the applications. Organizations supporting the objectives of ORCA are invited to apply for Corporate or Institutional Membership. Applications should be made to the Membership Secretary and should be accompanied by a statement describing the objectives of the organization applying.

The newly introduced membership categories will have the same benefits of ORCA membership as the regular members, including free online subscription to Caries Research, the official journal of ORCA. Full description of the privileges and responsibilities of ORCA members can be found in the Constitution and Bylaws that are available on the ORCA webpage.

In order to strengthen the internal democracy in ORCA the terms and election procedures for the Executive Board have been clarified in the Bylaws. Thus, the term for all the executives (except the President‘s office) will normally be limited to 5 years. The executive members, except the Vice-President, are nominated by the Board and take office on approval by the General Assembly. In case of several nominations to each office, the election must be confirmed by a secret vote of the Board Members. The Editor of “Caries Research“ can be elected for an additional term of 5 years, following the nomination procedure and approval by the Board.

The present report outlined some of this year‘s ORCA activities and changes that have been made to improve the functioning and further progress of the organization. I would like to thank sincerely all ORCA members for their engagement and support in all ORCA‘s activities that determine development of caries research in all parts of the world

Current ORCA Activities and Developments

ORCA Education Platform

As a result of an ORCA/ADEE joint activity, the European Core Curriculum in Cariology for Undergraduate 
Students (http://www.ncbi.nlm.nih.gov/pubmed/21757903) was released.
ORCA is now beginning to establish a Dental Education Platform which aims to continue this activity
and to provide an opportunity for bringing interested people active in teaching cariology together.
Initiator and chair is Andreas Schulte (Germany).

The first meeting of the ORCA Education Platform was at the 2013 ORCA Congress in Liverpool, UK. It was a two hours pre-congress event with reports from Colombia (Stefania Martignon), Germany (Ruth Santamaria and Christian Splieth), The Netherlands (Cor van Loveren and Guus van Strijp) and Norway (Alix Young) about the state of undergraduate education in cariology in these areas. The meeting ended with a fruitful discussion round on further activities. It was suggested to continue the reports about the teaching activities in cariology of dental schools. Furthermore, participants were interested to learn about the progress with the implementation of the European Core Curriculum in Cariology in Europe.
The next meeting of the Dental Education Platform will take place at the 2014 ORCA Congress in Greifswald (http://www.orca2014.org/) and will be announced in the final programme at the congress webpage.

ORCA Collection of Guidelines as to Caries Prevention Group (CGC Group)

ORCA´s further new activity is to provide an international collection of guidelines as to caries prevention which will be provided at the ORCA web pages.
The initiative was initiated by Carolina Ganss (Germany) and is chaired by Cor van Loveren (the Netherlands). The idea is to provide a source of information about global preventive strategies, in order to identify areas of consensus and disagreement, and to stimulate scientific discussion and future research perspectives. It may also help in providing support for areas where caries prevention is developing and to bring the best evidence available into dental practice.
Group members are Joana Carvalho (Belgium), Marilia Buzalaf, (Brazil), Stefania Martignon (Colombia) and Melinda Madlena (Hungary). All input is welcome.

ORCA Summer schools, Symposia and International Perspectives

  1. ORCA is carrying forward it’s tradition of Summer Schools and Symposia. The next event takes place in Colombia November/December 2013 where ORCA is offering a Caries Research Course (http://www.orca-caries-research.org/congresses/research_course.html) to stimulate and facilitate research related to cariology in this and in neighbour Spanish-speaking countries, where cariology interest is increasing.


  1. ORCA is organising an international symposium “Methodology of determining fluoride in toothpastes” which had been initiated by Nathan Cochrane (Australia). It will take place in Frankfurt, Germany at the end of 2014. Details will be announced on the ORCA web pages.
  1. ORCA intends to intensify contacts to other groups and associations active in caries prevention and welcomes joint activities! Ideas for activities related to the scope of ORCA can be brought to the ORCA Board by contacting the ORCA President.

ORCA Communication
- Overview July 2010

By Nigel Pitts, Past President

In recent years ORCA has been expanding its range of activities to ensure that it delivers on its objectives. To review them - ORCA’s Objectives are:

1. To promote oral health through scientific understanding of the aetiology, pathogenesis, prevention and clinical control or management of dental caries. Health outcomes related to dental caries are also of interest, as are other disorders of dental hard tissues.

- To evaluate the findings of research; to encourage their practical application; and to prevent their abuse.

- To establish close contacts between all individuals and organizations with similar aims, without distinction as to nationality.

2. ORCA shall be a not-for-profit organization

Current ORCA Activities and Developments (at June 2010):

Research in Cariology

  1. Participation in IADR Global Oral Health Inequalities Research initiative (GOHIR) – the Dental Caries Task Group has the ORCA President-elect and three further ORCA members sitting on it.

  2. A new Editor has recently been appointed for our Journal Caries Research, to build on the previous successes with a range of developments (including more on-line access) and  to increase further the all time high Impact Factor.  

  3. A new Senior Prize has been added to the ORCA fold; every three years we now contribute to the process of awarding the Yngve Ericsson Prize to complement the current ORCA Prize and the recently introduced Young Investigator Award.

Evaluation and communication of research findings and prevention of their abuse

  1. In association with the Association for Dental Education in Europe, ORCA organised a very successful ORCA / ADEE Workshop on a core Cariology Curriculum, held in Berlin from June 28-30. This provides excellent new Education links – a Supplement is to be published in the ADEE Journal
  1. Collaborations with the ICDAS Coordinating Committee continue across the domains of research, education, public health and clinical practice. The development of the ICDAS-Caries Management System (CMS) for Practice is a recent initiative. Following an April ICDAS Workshop in the US and a  pre-ORCA Symposium held on July 6th, a Synopsis of developments will be  published in Caries Research
  1. Participation in the FDI World Dental Federation’s Global Caries Initiative (GCI) continues. This started with meetings held in  Rio in July 2009, followed by ORCA participation in meetings held in Kuwait and Dubai. The GCI continues to evolve with a meeting in Salvador, Brazil in September 2010 for further build research to practice links.

International Perspectives

  1. In 2012 the ORCA Congress will be held near Rio in Brazil with a meeting linked with IADR Congress held around the same time.

  2. New arrangements have been made for International keynote speakers at each conference coming from range of countries with new disciplines represented – in 2010 there was an Education Speaker from the US.

  3. Engagement with the ICDAS Foundation and ADEA has resulted in the publication of an International Glossary of Cariology Key terms published by Karger and there is now on-going development with input from ADEE, ADEA and FDI.

Information to Members

  1. Developments of the ORCA Website are continuing to provide more information and facilities for members and linked dedicated web sites are now created for each ORCA Congress

  2. On-line abstract submission has been developed and introduced successfully. Feedback from members has been very positive.

  3. There is now an increased range of peri-ORCA Congress activities before and after the main Congress in order to build value for members and attract Congress participation.

Financial Matters

The ORCA Board is updating the way in which the organisation interacts with its various values corporate members in order to serve members better and meet sponsor needs more effectively.
