You are a Dental Practitioner without a digital system.

You make a photograph of the radiograph on your viewbox, or use a transparency adaptor to your flatbed scanner.

You refer the images to a second dentist and they are transferred efficiently.

PROBLEM: The JPEG images have no image file attributes to indicate patient unique identifier, date of exposure, or even R-L orientation. The radiograph could be misidentified as belonging to the wrong patient or incorrectly orientated.

SSCCEENNAARRIIO O ##11

You are a Dentist with digital X-ray system “A”

You make a dental Io image using System “A” and refer the patient to an Endodontist with System “B”. The image from system “A’ is displayed with System “B” . The Endodontist makes Endo completed images with System “B” and sends them to The GP.

The GP sends images from Systems “A” and “B” to a Prosthodontist with System “C”.

Images from “X,” “Y” and “Z” can be interoperable because all can use the DICOM file format.

DICOM IN DENTISTRY

• 1983: ACR-NEMA => 1992: DICOM => 1994: DICOM demonstrated by 25 vendors at RSNA infoRad

• 1996: DICOM Standards Committee “re-formed”: ADA was the first representative of organized Dentistry.

• 2000 (Summer): Six dental vendors meet at CAR/CMI San Francisco to investigate cooperation on digital interoperability/DICOM.

• 2000 (Fall): ADA House of Delegates Resolutions supports DICOM for image interoperability in Dentistry.

B-164.  Resolved, that the ADA adopt the Digital Imaging and Communication Standard (DICOM) as its standard for communication of digital dental images; and be it further

Resolved, that the appropriate agencies of the ADA develop and communicate a definition of compliance with the DICOM and other relevant standards that can be used by the members to ensure vendor's compliance and be it further

Resolved, that the appropriate agencies of the ADA develop a mechanism for recognizing vendors in compliance with the ADA definition of the DICOM and other appropriate standards.

• 2009: DICOM WG22 Task Groups formed in Japan and Europe as well as the USA. Membership evolves.

• 2010: AAOMR and AAO apply for DICOM Standards Committee Membership.

• Efficiency: Integration of different modalities in one dental office.

• Portability: Exchange of images between dental practitioners needed when patients move or require specialist care.

• Integrity: Attributes uniquely identify the patient, procedure, procedure date and protect image integrity.

WG 22 Work

There is a story about four people named Everybody, Somebody, Anybody, and Nobody.

There was an important job to be done and Everybody was sure that Somebody would do it. Anybody could have done it, but Nobody did it.

Somebody got angry about that, because it was Everybody's job.

Everybody thought Anybody could do it, but Nobody realized that Everybody wouldn't do it.

It ended up that Everybody blamed Somebody when Nobody did what Anyone could have. author unknown
