Volunteers needed for standards projects

May 21, 2012

By Jean Williams, ADA News staff


The Standards Committee on Dental Products is seeking volunteers for new standards projects.

Volunteers work together on documents that establish requirements for safe and effective dental products and technologies through a consensus-based process. Involvement is open to anyone who would like to contribute their expertise anywhere from the initial planning phase through reviewing final drafts.

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.

For more information or to participate in any of the projects below, call the ADA toll-free number, Ext. 2506, or email

Here are the new projects:

• Proposed Revision to ADA Standard No. 30 Dental Zinc Oxide—Eugenol and Zinc Oxide—Non-Eugenol Cements is an identical adoption of ISO 3107:2011 (of the same name) and specifies requirements for nonwater-based zinc oxide/eugenol cements suitable for use in restorative dentistry for temporary cementation, for bases and as temporary restorations. It also specifies requirements for non-eugenol cements containing zinc oxide and aromatic oils suitable for temporary cementation.

• Proposed Revision to ADA Standard No. 100 Orthodontic Brackets and Tubes is an identical adoption of ISO 27020:2010, Dentistry-Brackets and Tubes for Use in Orthodontics and is applicable to brackets and tubes for use in fixed orthodontic appliances. It gives details of methods to compare the functional dimensions of orthodontic brackets and tubes, the test methods by which they can be determined, as well as packaging and labeling information.

• Proposed ADA Technical Report No. 145 Interfaces for CAD/CAM will provide the definition of interfaces, which will ensure that the combination of components with those interfaces work seamlessly together to improve the quality of the final restoration and dental prosthesis.

• Proposed ADA Technical Report No. 146 CAD/CAM Implant Abutments will specify the development of methods by which the accuracy of scanned data used to facilitate the design of implant abutments can be evaluated for accuracy and precision of the implant interface. It will also evaluate adherence in design software to generally recognized standards for dental restorations and engineering principles related to the materials used.

• Proposed ADA Technical Report No. 147 Accuracy of CAD/CAM SLA Models will address the accuracy of data generated by digital scanners, the accuracy of data processing methodologies, and the accuracy of the manufactured model compared to the original specimen.

Additionally, the Council on Scientific Affairs and the Standards Committee on Dental Products have approved the circulation of the following draft standards for review and comment:

• Proposed Revision to ADA Standard No. 34 Dental Cartridge Syringes specifies requirements and test methods for aspirating, nonaspirating and self-aspirating dental cartridge syringes that are used with dental local anesthetics. This standard is not applicable to cartridge syringes having a mechanical-advantage action for creating high pressure.

• Proposed ADA Standard No. 134 Metallic Materials for Fixed and Removable Restorations and Appliances classifies metallic materials that are suitable for the fabrication of dental appliances and restorations, including metallic materials recommended for use either with or without a ceramic veneer, or recommended for both uses; and specifies their requirements. It further specifies requirements for packaging and marking the products and for instructions to be supplied with these materials. This standard does not apply to alloys for dental amalgam, dental brazing materials or metallic materials for orthodontic appliances (e.g., wire, bracket, band and screw).

• Proposed ADA Standard No. 141 Dental Duplicating Material specifies requirements and test methods for duplicating materials used in dentistry primarily intended for forming flexible molds needed to produce positive refractory investment copies of properly blocked-out master models.

• Proposed ADA Technical Report No. 1006 for Infection Control for Dental Information Systems provides general guidance for infection control measures to prevent transmission of potentially infectious microorganisms by information systems used in the dental setting. Devices and equipment specifically designed for dental use, such as digital radiography equipment, and devices intended for general use, such as computer keyboards, are addressed.
