Medical Forum / General / Dentistry / January 2005Frequency of X-rays
According to reports elsewhere new X-Ray equipment being installed at airports gives you a dose much like that of a dental X-ray machine. Which had me thinking... how frequently are you allowed to repeat dental X-Rays? >According to reports elsewhere new X-Ray equipment being installed at >airports gives you a dose much like that of a dental X-ray machine. > >Which had me thinking... how frequently are you allowed to repeat dental >X-Rays?

If you had the equivalent of a dental X-ray once a day (once a week?) would that breach any safety guidelines on exposure? > > As often as necessary ...... > > [quoted text clipped - 4 lines] > If you had the equivalent of a dental X-ray once a day (once a week?) would > that breach any safety guidelines on exposure? You get more radiation exposure walking in the sun then from dental x-rays. Especially now a days when we have super fast film F speed and digital x-rays. >> > As often as necessary ...... >> > [quoted text clipped - 10 lines] >Especially now a days when we have super fast film F speed and digital >x-rays.

What is film? .. Stephen Mancuso, D.D.S. Troy, Michigan, USA I am writing on a Tablet-PC,so forgive me if the PC misreads my handwriting. >> As often as necessary ...... >> [quoted text clipped - 4 lines] >If you had the equivalent of a dental X-ray once a day (once a week?) would >that breach any safety guidelines on exposure? Yes. A patient is limited to 0.5 rads per year. EPA, etc. >>>As often as necessary ...... >>> [quoted text clipped - 8 lines] > > EPA, etc. I'm a little rusty on the dosage calculations, but I assume that is a whole body dose. The skin dose at the end of the cone is on that order for a single film if memory serves, but the whole body dose for a single exposure is minuscule. I would also assume that the whole body dose for something like an abdominal CAT scan would be relatively very high. It comes down to what you said--risk vs. anticipated benefit. We don't hear this discussed in dentistry as much as perhaps we should. We do hear it discussed commonly when (for example) recommendations for age and first mammogram is discussed. Steve joel.

You may avoid deterministic effects with low doses, but stochastic effects are totally unpredictable and not dependent on dose. George Hey Joel, did you ever go to that botox seminar? |
