This report is proceedings of workshop at committee on PACS and medical information in Japanese society for oral and maxillofacial radiology on March 2016. Multiple use of dental image data, such as in the tele-radiology, computer assisted detection / diagnosis （CAD）, computer assisted surgery and forensic dentistry are proceeding. However, standardization of dental image data is not reached a sufficient level. Therefore, we establish a correction proposal of DICOM standard （CP1444） for viewing protocol of intraoral radiographs. In addition, we discussed about several aspects regarding the usage of dental data, such as the identity of the natural disaster related dead bodies and the development of new medical devises.
