The National Institute of Dental and Craniofacial Research (NIDCR), in collaboration with the Division of Oral Health, Centers for Disease Control and Prevention (DOH, CDC), has established a Dental, Oral and Craniofacial Data Resource Center (DRC). One element of the DRC is the Catalog of Surveys Related to Oral Health. The Catalog is a searchable electronic database that includes federal, state, international, and privately sponsored surveys and other datasets. Its purpose is to make researchers aware of surveys that have been conducted and to highlight features of complex surveys that relate to oral health. Other components of the DRC include an Archive of Procedures and Methods, Archive of Procedures and Methods Used in Oral Health Surveys, which is linked to the Catalog; an Annual Report, Oral Health U.S., 2002;and a data warehouse of acquired datasets. A Web-based statistical query system related to oral health is also under development. It is the intention of the DRC to meet the needs of NIDCR and DOH, CDC staff as well as other researchers interested in the status of oral health. The Catalog is available on CD-ROM at no cost and in the future will be made available through the NIDCR Web site.
