I went to the dentist yesterday and he had me take a panaroma xray. He
placed a lead protection vest covering my entire front of the body
with short flaps over the shoulders. but today, i realized that the
xray was coming from around the back of my head (ear to ear) and
shooting into film that rotated in front of my face. (ie. xray was
shooting from behind my head of the teeth to the film in front of me).
Since the xrays was coming from behind my head and my back side was
not protected at all i was wondering if this meant i was exposed to
the xrays?
thanks, rj. |

The lead apron is for "show". You were not exposed to any significant
amount of radiation.

What do you mean its for show? Were you joking or serious? So to
confirm, was i exposed to radiation because i was not covered in the
back? thanks!

The scattered radiation that bounces below the head is not enough to worry
about. The lead apron is there to put people's minds at ease.

Guess what? so is that "mask" dentists wear, a lot of the mercury
dust you kick up when you drill out fillings goes right through it.
Also, you know those $100 bills your patients have been paying you
with? They
are really $1's |

Congratulations, (siren goes off, and ballons start flying), that's
the millionth
unsubstantiated opinion on SMD, endorsed by the ADA. Four
scientifically unsubstainted opinions, in two posts = three sentences.
Gee, Your really good. |

So are you sweetie.
Hard to make 'mercury dust' cutting with a water spray.
Lose your mensa card?

Quote: Hard to make 'mercury dust' cutting with a water spray.
I don't think it is that difficult at all to create Hg vapor. Remember
that Hg isn't like most metals so it actually goes from vapor to a
solid to a liquid quite easily.The idea that the Hg remains bound to
silver throughout the drilling process is a fiction. When you drill an
amalgam and heat it, inevitably creating Hg in elemental form what %
of Hg is converted into Hg particles and then Hg in liquid form. Would
you splash water on a puddle of Hg?
Obviously It would seem that cooling the filling would reduce Hg
exposure from drilling but I would guess that 1) many dentists don't
use such a system or haven't in the past 2) It wouldn't eleminate it,
especailly with a high speed drill. 3) The patient can still ingest
the Hg (unless you've employed another advanced particulate suction
system).
.
Have you attempted to quantify what the actuall reduction in exposure
is for the patient and dentist for all three states Hg can take? Do
your ADA brochures say
how much of the pulverized amalgam is converted to elemental Hg? Do
they include a hypothetical table suchs as:
Type of equipment % of Hg converted to liquid % liquid-
vapor
Highspeed/drill
50 30
no water cooling
Low speed drill/
20 15
water cooling
Highspeed drill/
25 50
water cooling
Or do they just say, drilling fillings safe, ADA expert says so! |

Hey Dartos, are you trying to reason with someone's hatred? Might as well
try talking to your tractor. Speaking of which, tomorrow, my view out the
front window of the office is a Kubota dealer.

I'm sure many dentists use or have used unsafe methods for drilling
out fillings, in that they do not use or maximize water cooling. I
don't know what methods
you personally use. I was not refering specifically to you. Maybe you
have the most advanced water cooling, particle removal, oxygen mask/
air filtering system on the planet.
If a general dental standard exists requiring the use of water
cooling ( I hate to use the words "dental standard", because I know
none exists when it comes to Hg exposure and the ADA itself defends
itself in court as a trade organization) I'd sure like to see it, and
I would be very curios to see how or why that is rationalized in terms
of Hg exposure to the patient or dentist. |

I've been practicing dentistry for 29 years, and the last time
I was checked for mercury, I was lower than the U.S. average.
You can't check for Hg with a blood test, it is absorbed into the CNS.
I.E going to the doctor will not tell you how much Hg you have been
exposed to over 29 years, at best it may indicate recent exposure,
especially if you had drilled out any fillings in the past couple of
days. My understanding is
that lead does stay in the blood long term so it can be tested for,
but Hg is different.
You might also like to know that those most toxic, are less able to
excrete
Hg (because Hg inhibits certain enzymes) so they actually have lower
scores
on urine tests, and probably blood tests too. |
