  6. Information Regarding Dental Intra-Oral X-Ray Machine Assessment Program (DIQUAD©)   In March, 2009, the Department contracted with a commercial vendor – DIQUAD©, LLC, to screen dental offices via a mail out self-testing program. The program utilizes a small device which is able to assess radiation dose and image quality for both film and digital intraoral imaging systems. This program complements our on-site radiation safety inspections, and fulfills specific regulatory requirements. As with the on-site safety inspection, the cost of this service has been covered by X-ray machine registration fees. Participation in this program is mandatory as it is a vital component of the inspection program. The surveys must be completed and returned together with the test device according to the instructions provided by DIQUAD©.

We have provided information about this program to the state and local dental associations. Please follow the links below to view this letter and other information.

In most cases, this evaluation takes the place of an on-site evaluation, however, please be aware that some participants may be contacted for an on-site visit for follow-up or for quality assurance purposes. If you have further questions, please call the information line for this program at (916) 445-7433.
