Objectives: The purpose of this study was to develop a digital imaging and communications in medicine (DICOM) file for intraoral radiographic images and to develop a universal viewer system for the new DICOM file. Methods: Three kinds of intraoral digital systems were involved: an imaging plate using photostimulable phosphor (IP), a charge-coupled device (CCD) sensor and a film digitizing system. Three types of projections were involved: periapical, bitewing and occlusal. The images obtained by intraoral radiography were mapped to a template for 14 series by a newly developed DICOM file for intraoral radiographic images. The DICOM file for intraoral radiographic images, which was developed in cooperation with healthcare industry companies, had a newly defined tag with template code for image mapping and a location code in addition to the conventional tags. The images mapped were sent to an image server for PACS through networks and could be viewed in each terminal display by using a newly developed dental viewer. Result: The periapical images could be viewed as the same pattern of the mapping, and bite-wing and occlusal images could be arranged to be easily viewed on each terminal display based on the new tag information. The new DICOM file for intraoral radiographic images corresponded in the three digital systems and the three projection types. Conclusion: The newly developed DICOM file will be useful as a universal DICOM file for intraoral radiographic image.
