The DICOM standard (Digital Imaging and Communications in Medicine) is formed by a set of standards that allows interoperability of images, i.e. the exchange of medical images and associated data, regardless of manufacturer of equipment used in the acquisition and observation of these same images. In order to obtain some information about this standard, we did a bibliographic research in Medline, using "DICOM" and "Dentistry" as keywords, combined by the boolean operator "AND". This research had as limits: articles published in Dental Journals, which were written in English, between 1990 and 2011. According to the obtained results, we could observe that one of its main advantages was that it ensured the availability of all this medical information indefinitely, without loss of original picture quality, whatever the equipment that was used for storage and display in the future.
