ADA Standard No. 2000.2 - 2018 AMERICAN NATIONAL STANDARD/AMERICAN DENTAL ASSOCIATION STANDARD NO. 2000.2 FOR SNODENT (SYSTEMIZED NOMENCLATURE OF DENTISTRY) FOREWORD (This Foreword does not form a part of ANSI/ADA Standard No. 2000.2 for SNODENT (Systemized Nomenclature of Dentistry). The ADA SNODENT Canvass Committee has approved ANSI/ADA Standard No. 2000.2 for SNODENT (Systemized Nomenclature of Dentistry). The Committee has representation from all interests in the United States in the development of a standardized clinical terminology for dentistry. The Committee has adopted the standard, showing professional recognition of its usefulness in dentistry, and has forwarded it to the American National Standards Institute with a recommendation that it be approved as an American National Standard. The American National Standards Institute granted approval of ADA Standard No. 2000.2 as an American National Standard on December 3, 2018. A standard electronic health record (EHR) and interoperable national health information infrastructure require the use of uniform health information standards, including a common clinical language. Data must be collected and maintained in a standardized format, using uniform definitions, in order to link data within an EHR system or share health information among systems. The lack of standards has been a key barrier to electronic connectivity in healthcare. Together, standard clinical terminologies and classifications represent a common medical language, allowing clinical data to be effectively utilized and shared among EHR systems. Therefore, standard clinical terminologies and classifications, with maps to link them, must be incorporated into EHR systems to achieve system interoperability and the benefits of a national health information infrastructure. SNODENT enables the capture of information at a level of detail appropriate for the provision of oral healthcare and the interoperability of electronic dental records. Oral health information in SNODENT is recorded using standard identifiers that refer to concepts. The structure of SNODENT, through incorporation of synonyms, allows the recording of the information to be entered in a consistent fashion. The hierarchical nature of SNODENT allows the recording of the clinical information granularity and with different levels of detail (e.g. “dental caries”, is a “bacterial oral infection” or “disorder of hard tissues of teeth”). The nature of SNODENT hierarchies allows the clinical information to be retrieved and used in order to meet the requirements at various levels (e.g. retrieval of subtypes of “disorder of mouth” or “oral infection” would both include “dental caries”). The SNODENT concepts allow more specificity to be taken into account when retrieving clinical data. SNODENT content in this format is represented through the following components: Concepts — Represent clinical phrases that are organized into hierarchies. Every concept has a unique numeric concept identifier. Within each hierarchy, concepts are organized from the general to the more detailed. Related concepts are linked with the “is a” relationship. Examples of some of the hierarchies include “clinical finding”, “body structure”, “observable entity” and “organism”. SNODENT Identifiers - Each concept in SNODENT is assigned a SNODENT concept identifier. These identifiers are used in the descriptions and relationships files to refer to SNODENT concepts. There is no meaning associated with the identifier, that is, identifiers do not reflect the semantics of the terminology. The SNODENT identifier is an alphanumeric of six digits followed by the letter “D”. Within the six digits ADA Standard No. 2000.2 - 2018 2 SNODENT concepts are assigned a five digit number starting at 10,000. The SNODENT identifier format is therefore “nnnnnnD”.

ADA Standard No. 2000.2 - 2018 4 AMERICAN NATIONAL STANDARD/AMERICAN DENTAL ASSOCIATION STANDARD NO. 2000.2 FOR SNODENT (SYSTEMIZED NOMENCLATURE OF DENTISTRY) INTRODUCTION Unlike other areas of medicine, dentistry has infrequently used diagnostic codes of any sort. Most dental practice management systems were not designed to include diagnostic or other terms, beyond those used for payment purposes. The Systematized Nomenclature of Dentistry (SNODENT) was originally developed by the American Dental Association (ADA) using a consensus process involving all of the dental specialty groups as well as general dentistry, years ago to serve as a set of terms in dentistry primarily related to diagnostic terms that might be used. It has subsequently been changed since that time to reflect the current architecture of the Systematized Nomenclature of Medicine Clinical Terms (SNOMED CT). SNODENT now includes many of the other concepts found in SNOMED CT, including observables and substances. The scope of SNODENT was to provide a semantic interoperability for exchange of concepts. The initial extent of SNODENT was a vocabulary consisting of granular dental diagnostic concepts that could be used in electronic dental record systems. These concepts were developed based upon a predefined architecture. The ultimate objective for updating and enriching SNODENT is to ensure the inclusion of the perspectives of the dental profession. The terminology developed for electronic dental records must meet the needs of the clinicians where the care is being provided. For example, dentists should use concepts that have been developed and maintained by experts, including dentists, through a process coordinated by the affected stakeholders. SNODENT is a vocabulary designed for use in the electronic health records (EHR) environment and its features include: • An oral health resource with a granular clinical content • Provides consistent oral health content for use in electronic dental records • Is mapped to other standard terminologies As SNOMED-CT is a recognized code set and will be the basis for EHR development and certification, it is fully interoperable with SNOMED-CT which makes SNODENT the best choice for a clinical vocabulary required for dental systems. SNODENT will be used in dentistry to develop reference terminologies that will include terms for dental system interfaces. SNODENT has a broad coverage of oral health-related topics. It can be used to describe a patient’s oral health history, the details of a periodontal procedure, the spread of epidemics, and much more. At the same time, the terminology enables clinicians to record data at the appropriate level of granularity. Specific applications tend to focus on specific subsets of SNODENT, for example concepts related to dental caries, periodontal diseases or pediatric conditions. These subsets can be used to present relevant parts of the terminology, depending on the clinical context. SNODENT maps work to provide explicit links to health related classifications and coding schemes used in the United States such as ICD-9 CM, ICD-10 CM, and CDT. Maps facilitate use of SNODENT based clinical data for other purposes, such as quality measures and/or statistical reporting. ADA Standard No. 2000.2 - 2018 5 AMERICAN NATIONAL STANDARD/AMERICAN DENTAL ASSOCIATION STANDARD NO. 2000.2 FOR SNODENT (SYSTEMIZED NOMENCLATURE OF DENTISTRY) SCOPE SNODENT is a clinical terminology designed for use with electronic health records that enables the capture, aggregation and analysis of detailed oral health data. It includes oral anatomical sites, oral health conditions, findings, and other clinical concepts unique to dentistry. SNODENT enables patient data to be recorded by different people in different locations, and to be combined into simple information views within the patient record. It provides a standardized way to represent clinical oral health descriptions captured by dentists and enables automated interpretation of their observations.
