Abstract

A device is provided for filing a developed X-ray film such as a developed dental X-ray film. The filing device is formed of a transparent sheet. The transparent sheet has scale marks applied thereon, and is arranged such that a particular site, such as a tooth, in the X-ray film can be diagnosed using the scale marks. The filing device makes it possible to determine with precision and ease the size, relative position or the like of the particular site without removal of the X-ray film from the filing device.
