The most recent information available on the frequency of endodontic procedures comes from the American Dental Association Survey of Dental Services Rendered, conducted in late 2005-early 2006 and published in August of 2007. The survey is available from the ADA’s Health Policy Resources Center. A previous version of the survey was published in 1999, and the survey has not been repeated since 2005-2006. Information for the survey was collected using printed survey questionnaires and patient care logs, which documented the actual number of patients seen and the specific procedures completed. Data collected was used to compile national estimates for each dental procedure and specialty.
Relevant statistics from the 2005-2006 survey:
It is estimated that 22.3 million endodontic procedures were performed annually:
It is estimated that 15.1 million root canal treatments were performed annually:
It is difficult to compare the 2005-2006 data to the previous Survey of Dental Services Rendered (1999) because the ADA changed the way it collected and reported data. For example, retreatments, root canal obstructions, incomplete endodontic therapy and apexification were not part of the 1999 survey but were included in 2005-2006.
