Get involved: Volunteers sought for dental standards projects

May 25, 2018

Any dental professional with an interest in dental standards and technical reports can participate in the standards development process.

The ADA is accredited by the American National Standards Institute, or ANSI, to develop American National Standards and technical reports for products and information technology used by the dental profession and consumers. These standards and reports help ensure safety for providers and for patients.

Volunteers will review and comment on draft standards electronically; in-person meetings are not required. Standards can take one to three years to complete and there are often several reviews required during this development period.

Currently, there are more than 100 national standards and more are under development. Listed below are work projects the ADA Standards Committees on Dental Informatics and Dental Products are currently working on that need volunteer input.

The ADA Standards Committee on Dental Informatics is seeking volunteers for the following projects:

  • Proposed ADA Standard No. 1097 for Digital Caries Risk Assessment Resources. Caries risk assessment is an important consideration in the evidence-based management of dental caries in both children and adults and is essential to the development of clinical guidelines and advancement of dental quality initiatives. There is considerable variation among both analog and digital caries risk assessment tools currently in the use in the U.S. in terms of input data, scoring methodologies and reporting formats. This limits the ability to compare population caries risk data to validate the effectiveness of preventive recommendations and develop quality measures for caries prevention. This standard will provide a common platform for all stakeholders to measure individual and population risk factors for dental caries to improve the quality of clinical care.
  • Proposed ADA Technical Report No. 1098 for Quality Assurance for Cone Beam Computed Tomography and Proposed ADA Technical Report No. 1099 for Quality Assurance for Digital Panoramic/Cephalometric Radiography. Clear protocols will be developed in these two reports to ensure consistent production of X-ray images of high quality in order to provide the maximum amount of diagnostic information with minimal radiation exposure to the patient. The focus will be on testing and calibration of the X-ray source, image display device and software, and the image acquisition device and software for both types of imaging systems.

The ADA Standards Committee on Dental Products is seeking volunteers for the following work projects related to dental products and materials:


  • Proposed ADA Technical Report No. 133 for Guide To Dental Lasers And Related Light-Based Technologies: Technology, Science and Safety Considerations. Although the use of lasers in dentistry has been considered an emerging technology, use of lasers in health care first received Food and Drug Administration approval in the early 1980s. While there are many types of lasers, and the potential for procedures that can be performed seems almost limitless, this technical report will focus on the hard and soft tissue applications in dentistry and the recommended wavelengths to be used. The report will provide extensive scientific information on the use of lasers in dentistry with the purpose of facilitating the selection of the appropriate equipment. Additionally, the report will provide an understanding of potential hazards and safety considerations when lasers are used in the dental environment.
  • Proposed ADA Technical Report No. 168 for Guidance on Method Development and Validation of Cleaning Processes for Dental Instruments.  The ADA is developing a technical report that will provide guidance on the development and validation of cleaning processes for dental instruments, as part of the multiple-step procedure of reprocessing. It applies to cleaning prior to initial use as well as reuse. Validated cleaning processes are important in achieving consistently clean and biocompatible instruments, thereby eliminating the risk of re/cross contamination.
  • Proposed ADA Standard No. 165 for Vocabulary of Process Chain for CAD/CAM Systems. Manufacturers of computer aided-design/computer-aided manufacturing systems used in dentistry often use terms and instructions for use that differ from each other, which creates confusion among the dentists and technicians utilizing the systems. In order to overcome these ambiguities, this standard will provide a uniform terminology for use in the process chain for CAD/CAM systems.
  • Proposed ADA Technical Report No. 166 for Accuracy of CAD/CAM Digital Dentures, Data Captures, Function and Manufactures. Production of digital dentures is on the rise among users of dental CAD/CAM systems. This new technical report will provide needed guidelines for the data capture devices needed to design the digital denture; and for the materials, accuracy and aesthetics required to manufacture them.
  • Proposed ADA Standard No. 157 for Powered Dental Scaler Handpieces and Tips. As technical developments have resulted in improved scaler handpieces and tips, a standard is necessary to ensure optimum safety and performance. This standard will provide requirements and test methods for air-powered and electrical-powered scaler handpieces and scaler tips, including piezo, ferrostrictive and magnetostrictive type ultrasonic scalers.
  • Proposed ADA Standard No. 160 for Soft Lining Materials for Removable Dentures-Part 2: Materials for Long-Term Use. This standard will provide requirements for flexibility, adhesion, water sorption and water solubility for soft denture lining materials suitable for long term use, as well as for maxillofacial prostheses. This standard will assist dentists in selecting the appropriate material as more prosthetics involve staged treatment.
  • Proposed Revision of ADA Standard No. 57 for Endodontic Sealing Materials. This standard is being updated to include new endodontic materials based on tricalcium silicates.

The following ADA standards will be identical adoptions of the corresponding international standards published by ISO, or the International Organization for Standardization. Members may review these proposed new standards by contacting the ADA at
