The IADR Hatton Competition is designed to provide an opportunity for the best junior investigators from all IADR Divisions and Sections to present their research at the annual IADR General Session. Of these international competitors, up to six may receive monetary prizes and commemorative trophies in the junior and senior categories. Applicants must be an IADR member at the time of the abstract submission deadline and they must have won local IADR Division/Section Competition. Entrants may not compete in the same category they have previously won. For the Junior category, applicants must be currently enrolled in a BDS or DDS (Bachelor's and/or dental degree). This competition will be limited to those candidates who have carried out their research as part of undergraduate or professional training (research undertaken as an undergraduate science student, as a dental student, or at a time of pursuing an intercalated science degree while in training as a dental student). For the Senior category, entrants must be enrolled in a post-dental, post-graduate, or Ph.D. program or have performed the research submitted to the competition within three years of earning the award of PhD. Entrants for this category would have carried out research as part of a higher degree, either a Masters, PhD, or MD with previous laboratory experience, or as part of specialty training, and post-doctorals. The Senior Category is divided into two sections: Clinical/Pre-clinical Research, which involves research on human subjects and/or epidemiologic studies; and Basic Science Research, which involves laboratory or animal research. On the abstract form and presentation, the entrant must be listed first, as primary author and presenter of the abstract entered for the competition. Co-authors, if any, should also be listed on both the abstract and the presentation. Please visit the award's website or contact the International Association for Dental Research for more information.
