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 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 public review and comment until the dates listed below.

Proposed ANSI/ADA Standard No. 41, Dentistry – Evaluation of Biocompatibility of Medical Devices Used in Dentistry
Developed by ADA Standards Working Group 2.85: Biological Evaluation
This document specifies test methods for the evaluation of biological effects of medical devices used in dentistry. It includes testing of pharmacological agents that are an integral part of the device under test. This document does not cover testing of materials and devices that do not come into direct or indirect contact with the patient's body.
This proposed standard is a modified adoption of ISO 7405:2025, Dentistry — Evaluation of biocompatibility of medical devices used in dentistry and will cancel and replace ANSI/ADA Standard No. 41:2020.
Proposed ANSI/ADA Standard No. 57, Dentistry – Endodontic Sealing Materials
Developed by ADA Standards Working Group 1.5: Endodontic Materials
This document specifies the classification, requirements, and test methods for endodontic sealing materials used in endodontic procedures. It applies to materials used for conventional orthograde endodontic sealing (Type 1) and to materials used for other endodontic sealing procedures, including apexification, perforation filling, resorption treatment, or retrograde root-end filling (Type 2).
This proposed standard is a modified adoption of ISO 6876:2025, Dentistry — Endodontic sealing materials and will cancel and replace ANSI/ADA Standard No. 57:2021.
Proposed ANSI/ADA Standard No. 73, Dentistry – Endodontic Absorbent Points
Developed by ADA Standards Working Group 1.5: Endodontic Materials
This document specifies the requirements and test methods for sterilized absorbent points used in endodontic procedures. Absorbent points are marketed as sterilized or non-sterilized. The requirements apply to absorbent points which have been sterilized once in a manner approved by the manufacturer. This document specifies a numerical system and a color-coding system for designating the sizes of absorbent points.
This proposed standard is a modified adoption of ISO 7551:2023, Dentistry - Endodontic absorbent points and will cancel and replace ANSI/ADA Standard No. 73:2024.
