Medical Forum / General / Dentistry / July 2007Digital X-Rays
I know they're a Godsend to dentists because of low radiation exposure, and quick and easy filing and retrieval. However, I wonder how much resolution is lost in comparison to film X-rays? I wonder how often they cause misdiagnosis, if at all? - Bob Been using digital for ten years. I would say resolution, when viewed at the same size as the 1" X 2" film, is equal............ But,,,,,,,,,,,,,,,, with digital you can magnify 100X, you can modify the contrast and brightness. So you can use one film where you would have taken 2-3 in the past, and you can see much more. I would never practice with film again. The image begins to pixilate when you magnify it big enough that the entire image would fill a 5 foot x 5 foot screen. It is not perfect, but you can see much more and find caries much sooner (smaller).

Glad to hear that. I guess it's a matter of time until a wireless model comes out. Shoot the X-Ray, and it immediately starts uploading to the computer. By the time the assistant takes the infernal device is out of my mouth, I could see it on the screen. :D - Bob The wireless sensors are already available. They do not work in every office, though. Has to do with stray radio waves in the immediate environment. Signature/ Amatus / > >>Been using digital for ten years.

They were also quite big last time I checked. Won't be comfortable in every patient's mouth. Regards, George That is why I have both an electronic sensor and Phosphor plates in my office. The phosphor plates are thinner and softer than film (same sizes as film). Signature/ Amatus / >> The wireless sensors are already available. They do not work in every >> office, though.

[quoted text clipped - 4 lines] > > Bob I believe the studies still say that resolution of film is better than digital, but I can't see it. In any case, that assumes the film is not old, the developer is good, etc. etc. I would consider them equivalent, and expect I'll be making the move in the not too distant future. The ironic thing is that digital films with reused sensors came in just when sterility and cross infection became big issues in dentistry (again) with the emergence of HIV. Steve SignatureMark & Steven Bornfeld DDS http://www.dentaltwins.com Brooklyn, NY 718-258-5001 You re-use the sensor or the phosphor plate, but throw away the vinyl wrapper. Sterility is actually easier since you don't have to transport the contaminated vinyl wrapper out of the room. And,,,,,,,,,,,,,,,,,,,, almost every single digital image is useful. With film,,,,,,,,,,,,,, well,,,,,,,,,,,,,,, hmmm,,,,,, well,,,,,,,,,,,,,,,, maybe 90% ????
