Since 2007, the ADA has made the following changes to SNODENT:
- Eliminated the “Not Otherwise Specified” (NOS) designation
- Identified “frequently used terms” and added terms from the ADA health history form
- Assigned concepts to hierarchies
- Reviewed descriptions that were assigned to the concepts
- Reviewed synonyms for the concepts
- Developed a cross-walk from SNODENT to ICD-10-CM
- Obtained recognition of SNODENT as an American National Standard and instituted a formal, open, consensus-based change management process
- Harmonized SNODENT content with the Dental Diagnostic System (Formerly EZ Codes) to create a new reference set, SNO-DDS.
- Selected the most frequently observed, recorded, and diagnosed conditions from General Dentistry perspective to create SNO-DDS GD.
SNODENT now conforms to the “Vocabulary Desiderata”. The Desiderata identifies 12 characteristics that constitute a good vocabulary. Read more about the 12 characteristics.
SNODENT structure is made up of many concepts. It is not just diagnostic codes. It contains 18 categories divided between: “clinical findings,” “body structure,” “observable entity,” “physical objects,” “specimen,” “substances” etc. This allows SNODENT to be a comprehensive terminology for Electronic Dental Records (EDRs) and useful for information exchange.
