National Dental Practice Based Research Network (National Dental PBRN)

NIH/NIDCR awarded a seven-year (2019 to 2026) $22.4 million grant to continue the National Dental PBRN to improve the nation’s health. The University of Alabama at Birmingham will serve as the National Administrative and Resource Center (PI: Gregg Gilbert). The University of Illinois at Chicago will serve as the Specialty Engagement Node. Dr. Sath Allareddy (AAO Member) will serve as the National Director of Specialty Engagement. The network comprises a National Administrative & Resource Center based at the University of Alabama at Birmingham, a central Data Coordinating Center based at Kaiser Permanente Center for Health Research, and six regional nodes.

AAO Practice Based Research Network Studies

The AAO created the Practice Based Research Network Committee (AAO-PBRN) in 2013 to encourage orthodontic research in network settings, especially in the National Dental Practice Based Research Network (”network”).  The AAO-PBRN has been instrumental in moving several orthodontic studies forward, and this site provides information on studies which are in various stages of development.  It also provides additional information on the network, as well as links to enrollment.  We hope you will consider participating in one of the upcoming network studies, and urge you to enroll in the network. Due to the transition to a new funding cycle and a new Data Coordinating Center, we anticipate that the new Enrollment Questionnaire will be available sometime in August 2019.
