Systematized Nomenclature of Dentistry (SNODENT) is owned, maintained and distributed by the American Dental Association (ADA). SNODENT is a vocabulary designed for use in the electronic environment - for electronic health and dental records. The intended purpose is to:

  • Provide standardized terms for describing dental disease
  • Capture clinical detail and patient characteristics
  • Permit analysis of patient care services and outcomes
  • To be interoperable with Electronic Health Records (EHR) and Electronic Dental Records (EDR)
