[Oradlist] Intraoral X-ray phosphor viewing screen

[Abramovitch, Kenneth]

Douglas's question has  captured my interest.  I reviewed Raper's 1913 text.  There is a photo of the mirror and a clinical photo of a patient during a fluoroscopic exposure.  The text states disadvantages of the instrument as:
Both operator and patient exposed
Keep times short to avoid them being "exposed to the rays unnecessarily or dangerously long"
The fluoroscopy picture lacks detail
No archival record of the image

From:  Raper HR.  Elementary and Dental Radiography First Edition.  1913, pp.144-145. p.143 (illustration)

I have this image in my History of Radiology Lecture, and older version of which is buried in the Radiology Centennial Time Capsule (the lecture that is). I have it that Rollins was the inventor of this. I also seem to remember that they were banned much before 1950s.

Dear all,

In the dental museum of University Museun in Utrecht, The Netherlands, they do have an ones of these mirrors (including the original box) on display. Actually, the diameter of the ``mirror`` is slightly bigger than the one of Douglas.
I doubt that these stil lwere in use in the 1950s.

Best regards

ORADlisters in general and Douglas Benn in particular--

The device you pictured is a mouth mirror with the glass replaced by a
phosphor screen.  It was typically called an intraoral fluoroscope.
Apparently some dentists were using them in the 1950s.   I can vaguely
remember a class discussion at Emory with Dr. S. P. Vail (an early member
of AAOMR) warning us not to use them.  I also vaguely remmbr an
illustration in an old dental radiology textbook.
