New standards available for purchase from ADA Store

The American Dental Association Standards Committee on Dental Products has approved the following new standards that are now available from the ADA:

• Revised American National Standards Institute/ADA Standard No. 39 for Pit and Fissure Sealants specifies requirements and test methods for polymer-based materials intended for sealing pits and fissures in teeth.

• Revised ANSI/ADA Standard No. 53 for Polymer-Based Crown and Veneering Materials classifies polymer-based crown and veneering materials used in dentistry and specifies their requirements. It also specifies the test methods to be used to determine conformity to these requirements.

• Reaffirmed ANSI/ADA Standard No. 73 for Dental Absorbent Points specifies requirements and test methods for nonmedicated absorbent points used in endodontic procedures.

• Reaffirmed ANSI/ADA Standard No. 78 for Dental Obturating Cones specifies the dimensions and requirements for prefabricated metallic or polymeric-based cones suitable for use in the obturation of a root canal system restoration. It also specifies the numerical and color-coding systems for designating sizes.

• Reaffirmed ANSI/ADA Standard No. 80 for Dental Materials — Determination of Color Stability specifies a procedure for determining the color stability of dental materials after exposure to light or water.

• Revised ANSI/ADA Standard No. 96 for Dental Water-Based Cements specifies requirements and test methods for powder/liquid acid-base dental cements intended for permanent cementation, lining and restoration in part one. Part two specifies requirements and test methods for water-based dental cements in which setting is achieved by a combination of an acid-base reaction and polymerization.

• Revised ANSI/ADA Standard No. 116 for Oral Rinses specifies physical and chemical requirements and test methods for oral rinses. It also specifies the accompanying information such as the manufacturer's instructions for use, marking or labeling requirements.

• Revised ANSI/ADA Standard No. 130 for Dentifrices — Requirements, Test Methods and Marking specifies requirements for the physical and chemical properties of dentifrices and provides guidelines for suitable test methods. It also specifies requirements for the marking, labeling and packaging of dentifrices.

• ADA Technical Specification No. 150 for Method for Determination of Polymerization Shrinkage Stress of Polymer-Based Restorative Materials specifies a test method using an instrument, designed for accuracy and sensitivity to the presence of shrinkage, for the measurement of polymerization shrinkage stress of external- or internal-energy-activated, polymer-based restorative materials, such as composites and core materials.

• ANSI/ADA Standard No. 177 for Central Suction Source Equipment specifies requirements and test methods for stationary, electrically powered central suction source equipment, including centrally located amalgam separators and air water separators. It also specifies requirements for information to be supplied by the manufacturer on the performance, installation, operation and maintenance of the central suction source equipment as part of the complete dental suction system.

• ANSI/ADA Standard No. 179 for Shanks for Rotary and Oscillating Dental Instruments specifies the requirements for dimensions and material properties of shanks used in dentistry for rotary or oscillating instruments. It describes the measurement methods for the verification of the requirements.

ADA standards and technical reports are available for purchase from the ADA Store. The ADA has implemented a new sales system that will make the process of obtaining ADA standards and technical reports easier and more convenient. When purchased, documents will now be instantly available for online viewing and a hard copy will automatically be mailed to the customer. Downloading and printing of documents will no longer be available.

Certain ADA standards and all ADA technical reports are available for free viewing to ADA members.

The ADA is accredited by the American National Standards Institute to develop American National Standards and technical reports for products and information technology used by the dental profession and consumers. Currently, there are more than 100 national standards and more are under development. National standards developed by the ADA serve the dental profession by ensuring product safety and efficacy for both clinicians and patients and providing information on new and emerging technologies.
