-Info I've collected on the dental x-ray sensors that I got from UNIXSurplus at DEFCON 22.  The bare senors are generally in poor condition.  Its possible yours work but generally they are non-functional or have other problems.

-WARNING WARNING WARNING

-Bond wires are exposed!  Be very very careful handing these!

-WARNING WARNING WARNING 
- 
-JM inventory: 
-  * Unit: bond wires partially covered in glue.  Wires in perfect condition / intact 
-  * Unit: bond wires ruffled but looks okay 
-  * Unit: bond wires overall in good condition.  HOWEVER, a small section was ruffled and a wire broke (PCB side).  As they are aluminum I don't know if I can solder it 
-  * Unit: bond wires in good condition.  No scintilator (and it looks like it never had one: no glue marks etc) 
-  * Unit: in overall very poor condition.  No bond wires.  PCB has severe damage.  Sensor has severe damage.  Scintilator is damaged and separated from sensor
