It's to increase profits and pay for the equipment. As a child I had many, many dental x-rays. Even now, they continue to scale back their frequency, in some locations. It's clearly moronic, the window for hormesis is finite and varies by individual. Digital xrays lessen exposure, but are still significant. In other locations however, they've come to fancy them new fangled cone beam CT machines. And by the jimminy geez I just gotta have one and once I got one well... I ought to use it, that wasn't cheap! Good thing insurance will pay...
And that's the racket. Least a part of it. The mere notion of doing ct scans on a child's head and thyroid region is obviously asinine. Xrays don't move in a straight line either, they like to scatter everywhere internally. Which is why the dentist / radiologist leaves the room; they'd be getting many times the dose of an individual patient per day.
Also, it's not comparable to a plane ride. Getting hit wit cosmic rays and muons isn't the same as a concentrated dose on a very precise region, all at once. Let's just stop the bullshit before it even begins.
Also, let's bear in mind in the 50's there were xray machines used for shoe fitting. Just sitting around the store. Kids would have fun playing in them, of course.

>but are still significant in the levels that people receive them during dental visits throughout the years, they really aren't significant. We can't even show that CT scans are significant. >Getting hit wit cosmic rays and muons isn't the same as a concentrated dose on a very precise region also not true or important. "concentrated dose" doesn't mean anything.

>they really aren't significant. During critical developmental windows, yes, it is.
>"concentrated dose" doesn't mean anything. Someone who doesn't think about things on a physical level isn't worth talking to. You might as well be saying clear cutting a chunk of forest will yield the same macro effect over time, as cutting down a few trees here and there. That's not how cellular machinery works. It's not magic.

>During critical developmental windows, yes, it is. well, sure but I suppose I'm speaking for myself and other 20 somethings. the dose you receive to the area when given an x-ray is extremely low. lets say you're getting what OP has gotten done, a full mouth series. ~18 digital x-rays can come out to as high as 0.01 mSv. That's the equivalent full body dose. That is very low and not to be concerning over. To your head, that is 0.0001 mSv that it received. How is this something to be concerned about, exactly? It's equivalent of just existing for a few weeks. Acute doses are not significant at such low levels.

>dental hygienists are prone to getting thyroid cancer after like 20-30
My mom has been a dental hygienists for 20 years. Why did you have to tell me this?
Robert Edwards
Thyroid cancer isn't a big deal, don't worry. There are forums basically for dentists/dental hygienists that talk about specifically that. It's not like all of them get it, but it seems like a lot do.

It makes a difference whether an amount of radiation is spread out over your entire body, or the same amount gets shot right at your thyroid gland.
Connor Bell
>It makes a difference whether an amount of radiation is spread out over your entire body, or the same amount gets shot right at your thyroid gland. Fuck, you really don't know what you're talking about.
The 3 mSv you receive per year from background radiation... this is your full body dose.
This is what the "Sievert" unit is. The 0.01 mSv you receive from a full mouth series is the full body dose. You aren't actually receiving 0.01 mSv to your head. You receive the weighted dose, and to your head, that is about 0.0001 mSv, totally insignificant.
Do you fly, ever? At 36,000 feet, you are receiving doses in the same range.
You really don't know what you're talking about, and don't hide behind "i'm talking about very young children during their critical development window" because fucking nobody ITT is other than you.

>It makes a difference whether an amount of radiation is spread out over your entire body, or the same amount gets shot right at your thyroid gland. "concentrated dose" isn't a term, and has no definition in radiology or anything related to imaging physics. you're on Veeky Forums so you may be talking to people actually in the field.
Anthony Williams
Yeah the dose might be small, but its the repeats what's dangerous Also that they seem so careless and random And that they don't hesitate, and that they do it to everyone
