Idea Exchange: DIY dental radiograph viewer
If your hospital doesn't have a viewer for dental films, you can make a screen by using the cardboard in a large x-ray film box. This cardboard should be large enough to cover the regular radiograph viewer. Just cut out a template of the dental film in the middle of the cardboard, and place it over the viewer when needed. I draw a cartoon mouth around the hole, so everyone knows what I use it for.
