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)
