Submission Guidelines

The abstracts for presentation at the 71th 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.

All abstracts will be reviewed by the Scientific Program Committee. 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 Abstracts cannot be withdrawn after that. If an abstract is not withdrawn by that date, and the paper is not presented, the named presenter will not be allowed to present any paper at the following ORCA Congress.

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 not been published or presented already and has not been 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 present the paper in person at the Congress. All presentations are conducted as poster sessions and include the presence at the poster at a set time as well as a short oral presentation and discussion in the audience which will be streamed online.
  • Posters and Slides for the oral presentation must be uploaded in the submission system.
  • Two slides are possible, but animations are not allowed. For further details, also for how to prepare the poster, please see the Congress webpage.
  • Deadlines are: – Posters (PDF file max 5Mb) Monday 3 June 2024 13:00 CET,- Slides (PPT file max 1MB, 2 slides without animations) Friday 21 June 2024 13:00 CET.

Presenters should:

  • Ensure that they will have the necessary funds to attend the Congress
  • Apply for any necessary visas in good time, to ensure that they can travel to the Congress to present their paper
  • Ensure that any abstract describing commercially-funded research has been approved by the funding company before submitting it
  • Write their abstract exactly according to the instructions given below and are urged to seek help from the Master Abstract.

Presenters will be asked for the following items:

  • Surnames and initials of the presenting author, corresponding author and other authors
  • The email address of 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; 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. Vague expressions such as ‘the results will be discussed’ could result in rejection of the abstract. Include references only when they are essential and follow an abbreviated Caries Research format, but omitting the authors’ initials and the title, and using ‘et al.’ for multiple-author works. Example: [Main et al.: J Oral Rehab 1983;10:307-313]. Tables, photographs, graphs or diagrams are not allowed. Acknowledge sources of funding in the designated field outside the abstract text.
  • One of the following key phrases, which are required to assist programming: Artificial Intelligence; Behaviour; Clinical Studies; De- and Remineralization; Diagnosis; Education; Epidemiology; Erosion; Fluoride; Hard Tissues; Microbiology; Public Health; Pulp-Dentinal Reactions.
