ADA Standards Committee seeks comment on new specifications

The ADA Standards Committee on Dental Products has approved for circulation and comment proposed revisions to two American National Standards Institute/ADA Specifications. They are:

• No. 53 for Polymer-based Crown and Bridge Materials classifies polymer-based dental crown and bridge materials and specifies their requirements. It also specifies the test methods to be used to determine compliance with these requirements.
• No. 119 for Manual Toothbrushes describes requirements and test methods for the physical properties of manual toothbrushes in order to promote the safety of these products for their intended use.

Copies of these draft specifications are available by calling the ADA toll-free number, Ext. 2506, or sending an e-mail request to standards@ada.org.
