Delta Dental's Research and Data Institute

Supporting Oral Health Research with Data and Analysis

In 2005, Delta Dental established the Research and Data Institute (RDI) to provide researchers and scientists with resources to support high quality, innovative research which will improve oral health and overall health.

Those resources include an extensive claims database and expert data analysis by a staff of actuaries, statisticians, epidemiologists, economists and dentists who work together to effectively analyze and examine data, trends and outcomes in dental science.

From proof-of-concept projects through multi-year groundbreaking trials, the RDI has a proven track record of successfully partnering with some of the largest university and biotech research facilities in the country to produce studies which are empirically sound and highly regarded.

The Largest Claims Database in the Country

As a result of specializing in dental benefits for nearly 60 years, Delta Dental has developed a breadth of experience and a collection of resource data that rivals the size of the estimated print content of the Library of Congress. We routinely partner with our large customer groups, many of whom we have served for decades, to utilize data that allows us to track members over extended periods of time. As a result of our dedicated research collaborations, our claims data experience can provide valuable insight into oral health status, care utilization and treatment patterns.

It's All About the Data

The RDI has immediate access to a robust collection of longitudinal dental claims data which includes:

  • 596 million dental treatments spanning more than 840 unique procedures,
  • 30 years of history and all 50 states;
  • 10.1 million total members across all age cohorts;
  • More than 1 million subscribers with at least 10 years of continuous coverage and more than 450,000 subscribers with 15 years or more.
