ADA Standards Program volunteers work together on documents that establish requirements for safe and effective dental products and technologies through a consensus-based process. The ADA has played a key role in the development of dental standards since 1928 and is an American National Standards Institute (ANSI) Accredited Standards Developer. The Working Groups that develop ADA standards are a diverse group of expert volunteers representing dental practitioners, industry, government and academia. Professionals from all areas of interest are encouraged to participate. Involvement is open to anyone who would like to contribute their expertise.
The following draft standards are available for review and comment during the ANSI Public Review period until the dates listed. To request a copy for review, contact standards@ada.org.
New Standards/Revisions:
Proposed ANSI/ADA Standard No. 47-2, Dentistry – Stationary Dental Units and Dental Patient Chairs – Part 2: Air, Water, Suction and Wastewater Systems
Developed by ADA Standards Working Group 6.35: Dental Chairs, Units, Stools
Modified adoption of ISO 7494-2:2022, Dentistry — Stationary dental units and dental patient chairs — Part 2: Air, water, suction and wastewater systems
(Available for comment until November 24, 2025)
This document specifies requirements and test methods for stationary dental units concerning:
a) the properties of stationary dental unit connections to the compressed air supply, water supply, suction supply, and wastewater drain plumbing,
b) the materials, design, and construction of the compressed air and water system within the stationary dental unit,
c) the quality for incoming water and air,
d) the performance of stationary dental unit suction system, and
e) the air, water, suction and wastewater properties of stationary dental unit connections to the interfaces to dental handpieces.
This document also specifies requirements for instructions for use and technical description. This document does not specify requirements or test methods for the effectiveness of stationary dental unit waterline biofilm control.
NOTE Test methods for the effectiveness of stationary dental unit waterline biofilm control are specified in ANSI/ADA Standard No. 167/ISO 16954.
This document is only applicable to stationary dental units that are not used for oral surgery treatment requiring sterile air and water supplies. Amalgam separators are not included in this document.
Proposed ANSI/ADA Standard No. 174, Dentistry – Hose Connectors for Air Driven Dental Handpieces
Developed by ADA Standards Working Group 4.29: Handpieces
Modified adoption of ISO 9168:2009, Dentistry — Hose connectors for air driven dental handpieces
(Available for comment until November 24, 2025)
This document is applicable for achieving reliable interchangeability between hoses from dental units and dental handpieces.
This document specifies four types of hose connectors for use between air driven dental handpieces and the flexible hoses of the dental unit which supply the handpieces with water, air and light, and provide for exhaust.
Proposed ANSI/ADA Standard No. 1058, Dentistry – Forensic Dental Data Set
Developed by ADA Standards Working Group 10.11: Forensic Odontology Informatics Terminology
Modified adoption of ISO 20888:2020, Dentistry – Vocabulary and designation system for forensic oro-dental data
(Available for comment until December 1, 2025)
This standard specifies the coupling between handpieces and motors connected to dental units. This standard specifies the nominal dimensions, tolerances and extraction force of coupling systems for use between handpiece and motor which supply the handpiece with water, air, light and rotation energy.
Proposed ANSI/ADA Standard No. 1100, Dentistry – 2D and 3D Orthodontic/Craniofacial/Forensic Photographic Views and Viewsets
Developed by ADA Standards Working Group 11.6: Integration of Orthodontic Standards
(Available for comment until November 24, 2025)
The scope of this document is to provide: a list of possible intraoral and extraoral visible light image (photographic) views as used by orthodontic/craniofacial/forensic providers; explanations and specific attributes of each view, making use of text and line art drawings where necessary; and terminology that includes necessary terms for encoding orthodontic views and viewsets. This standard is suitable for use in assigning tags, fields, and information to visible light image (photographic) views for implementation guides and profiles.
Proposed ANSI/ADA Standard No. 101-5, Dentistry — Endodontic instruments — Part 5: Shaping and cleaning instruments (Previously ANSI/ADA Standard No. 28:2021)
Identical adoption of ISO 3630-5:2020, Dentistry — Endodontic instruments — Part 5: Shaping and cleaning instruments
(Available for comment until November 24, 2025)
This document specifies requirements and test methods for hand-held and mechanically operated instruments used for shaping and cleaning root canals, and which are not specified in other parts of the ADA endodontic instrument standard/ISO 3630 series. This document specifies requirements for size, marking, product designation, safety considerations, labelling and packaging.
