The National Dental Practice-Based Research Network (PBRN) conducted a study to describe the characteristics of its member dentists in the United States and determine how often they provide specific dental procedures. The results showed that dentists participating in the National Dental PBRN have much in common with dentists at large. The network has a broad representation of dentists, practice types, patient populations, and treatments offered, including diversity regarding race/ethnicity, gender, insurance, and geography of its practitioners and patients.
