The most important dental research meetings are held worldwide. When the IADR General Session & Exhibition and the AADR/CADR Annual Meeting & Exhibition occur as a combined event, it attracts over 6,000 participants. Every other year, the IADR General Session (outside North America) and the AADR/CADR Annual Meeting (in North America, usually the United States) occur separately, each attracting from 4-6,000 participants. The meetings consist of individual oral and poster presentations and symposia/workshops on topics of major interest to the scientific community. Abstracts from the meetings are published online and/or in CD-ROM form as Special Issues of the Journal of Dental Research (JDR). Both meetings are excellent forums for the presentation of current dental and collateral research findings.
