Unhappy Bringing film to dentist

I carry my camera bag with me everywhere. Even to the dentist today. I really should have thought this one through. I had a total of 18 X-rays done and my camera plus 5 rolls of 120 film where in the same small room. Is my film fogged? Anyone know the impact of dental X-ray on film? Thanks.

Would rather not ruin good shots or spend the money on developing if the chance of fogging is high.

Dental X-ray exposures are lowish in kVp but exposure times can be quite high. Intensity is a factor of the time, whilst kVp affects energy/penetration or how far the radiation will travel and through what. The film would have to be in the firing line or near enough to get some scattered radiation.

The energy drops off with the inverse square of distance, so if your bag was some feet away, it should be fine. Your head absorbed most of it.

I can't see this being an issue... I've photographed in a dentist's office before while a friend was getting her teeth done...xrays and all.

I've regularly carried my Leica in my bag on visits to the dentist. I've never had any problems.

You could ask the dentist ... but what would he/she know?

They all own M9's!

If your brains were fogged when you came out you have bigger things to worry about.

I was a Dentist, and you should not have a problem. The X-Ray machines used in dentistry are highly colliminated (shielded). The bag would have to be on the other side of your face to have a effect, if even then.

I agree, don't worry. If there were any concerns, dentists would be dropping like flies.

My wife goes to a dentist who keeps some sort of Barnack in his office. I'm thinking of switching to her dentist and will report back when I get to the bottom of what he uses. The Mrs. was alert enough (not easy given the torture he performs on her) to notice that it had a collapsible lens.

In any case, you weren't wearing the camera on a neck strap while having 18 x-rays shot, were you? Then, don't worry AND listen to Dr. Carter.

There's a dentist here and he is right of course. I do wonder about 18 X-rays and the indication for that.

I think a dentist's x-ray schedule is directly proportional to insurance coverage.

... I wonder if 3D CT would not be easier and faster in this case ?

From what I have read, you get a lot more radiation from an airplane flight (cosmic radiation) than from a dental x-ray.

Don't ask where I read it, or how long the flight!

Medical X-Ray exposure of staff is carefully regulated. What to the patient or parent might be negligible exposure at an annual visit, would potentially be cumulatively significant to staff exposed throughout every working day.

It is one very important nerve* that would worry me about the 18 X rays, not the radiation exposure.


* The hip pocket nerve.

I had one of those done in preparation for an implant. I was amazed at the detail and the way the 3D image could be rotated to change the viewpoint. The surgeon could really see what he was working with - brilliant use of technology that allowed him to avoid damaging nerve channels in the bone.

Radiation damage is cumulative, isn't it? If I had to do hundreds of xrays a year (as operator) I'd be running for cover too. Sensible precautions for both the patient and the operator.

One more thing: In these days of safe exposure limits for patient and operators, X-ray intensities are as low as feasible, and X-ray film is sandwiched with intensifiers to be able to record any image at all under these restrictions. The effect of X-rays on regular film would be too low to record as a usable image even if you'd put it where the dentist's film was placed.
