Call for Abstracts

The procedure is complete

Submission Guidelines

The abstracts for presentation at the 71st ORCA Congress will be published in an online issue of Caries Research. This issue will be the only abstract book for the Congress and will be available online, free of charge.

The deadline for submitting an abstract is 15 January 2024 new date 22 January 2024. Each presenter can only submit one (1) abstract.

The Scientific Program Committee will review all abstracts. Authors will be notified of acceptance or rejection of their abstract by 29 February 2024 and, at that time, may be asked for revisions. Any such revisions must be submitted by 10 March 2024. Abstracts cannot be withdrawn after that. If an abstract is not withdrawn by that date and the paper is not presented, the named presenter will not be allowed to present any paper at the following ORCA Congress.

Upon acceptance of an abstract, the presenter must proceed to register to the Congress.

If you wish to apply for the ORCA Conference Travel Fellowships or ORCA Junior Scientist Award, you can do so until the abstract submission deadline in the abstract submission system. You can find more information at:

Presenters should note the following:

  • The Congress focuses on research into dental caries and related topics.
  • Abstracts must describe research that has yet to be published or presented and has yet to be submitted to another meeting at the time of submission for the ORCA Congress.
  • Authors may present only one paper at the Congress but may co-author other papers.
  • The presentation at the Congress must conform to the material in the published abstract. Once submitted, abstracts can be edited within the submission system until 15 January 2024 and during the period for revisions from 29 February to 10 March 2024. Afterwards, corrections are limited to numerical errors or typos and will be done by the Editor only prior to publishing.
  • Those who submit an abstract are committed to presenting the paper in person at the Congress. All presentations are conducted as poster sessions and include the presence of the poster at a set time, as well as a short oral presentation and discussion in the audience.
  • Posters and Slides for the oral presentation must be uploaded in the submission system.
  • Two slides are possible, but animations are not allowed.

Presenters should:

  • Ensure that they will have the necessary funds to attend the Congress

  • The email address of the authors.
  • Brief affiliations of authors (institute, city, country only).
  • Title of abstract. This should be 15 words or less.
  • Text of abstract. This should be 280 words or less and should state: the aim of the work; the experimental approach; the main results; and the conclusions. The results must include key numerical and statistical data but do not attempt to report data exhaustively; SI units should be used. The conclusions should be explicit.
