That's one theory of what happened to Rome. Do you think there's any basis for basing the estimated risk on the actual amount of lead involved, or is that just foolishness?
They didn’t know any better.
If i find out my new crown was made in Leadsville china, I am punching someone’s teeth out!
“Kind of odd that people can walk around with bullets (990,000 ppm?) in them for years and not have that happen.”
I’m still walking around with a fair amount of a bullet in my left leg. Been there for about thirty years. No problem.
Elemental lead is not dangerous: It’s the oxides of lead (and other lead compounds)that are dangerous as the body can easily absorb them.
Isn't occupational exposure based on external levels?
...and then that would be affected by the possibility of breathing in lead-laden dust, etc. depending on circumstances.
Here's a related question. There is still epidemiological evidence on toxicity of lead-based paint, on inner-city children who eat chipping paint.
Would it be possible to back into a toxicologically significant dose (crowns and paint chips both are inside the mouth...) from that data?
Cheers!
In this case, the body has to separate it from an amalgam/alloy (at 210 ppm) first. I'm just not seeing the potential to get enough lead exposure from one of these to cause the problems that are being attributed to it.
I'll try again tomorrow...
Thanks, and
Cheers!
Look at the video and see the inflammed tissue and try saying that again. While your at it, inform the Ohioan lady in this video “It’ll be okay”
“I’m just not seeing the potential to get enough lead exposure from one of these to cause the problems that are being attributed to it.”
I kinda doubt it myself. People just freak out when the word lead comes up.
I always get someone warning me about how dangerous casting my own bullets is. The biggest danger is spilling hot lead on yourself!!
I actually have some molds for lead soldiers that kids of my grandfathers generation used to make their toys!
The 40ug/dl is blood levels. If you work around lead and your blood levels get above that you're supposed to get moved to some less contaminated environment until they drop below that.
As far as the other question goes, I guess it might be possible (lots of "ifs" there), but if this person suspected they'd gotten lead poisoning from their dental work I'd think they'd go get the bloodwork done to verify it, and we'd be reading about it in the article.
Cheers!
They found lead in the crown, so that has to be what caused it. No other explaination is possible or any other possibility worth considering? You're way too easy.
So my gold crown could have lead in it?
Yesterday, I received an email from the National Association of Dental Laboratories (NADL), outlining this problem with Chinese dental lab products.
They pointed me to their website to get updates on the story. When I got there, the story and updates were only available to NADL paying menbers with a site user account. Pretty useless.
Do a search online for dental labs; you should get plenty of hits. Dig a little deeper and look for fee schedules or price lists. You won’t find many. The story was much different, even 5 years ago. Lots of labs published their prices.
The dirty little secret is that the $600 - $1200 you paid to a dentist for a crown has a lot of in dental office markup.
In most cases when a dental office sends out crown work, the cost of a crown from a domestic dental lab to that same dentist is $80 to $250. (I know some of the folks getting $250, they are very exacting artists/craftsmen, worth every penny. They represent a very small fraction of the work sold in the US today) Work sent overseas commands as little as $55. Sure, the dentist did a crown prep and took impressions, and then cemented the restoration into place, but did he really deserve that huge markup?
The story also seeks to portray the dentists as victims of underhanded dental labs, both domestic and foreign. What a crock. Did anyone seek to find out just what percentage of dental work sent to China from the US is sent by labs and what percentage is sent directly by dentists? Of course not, or the average dentist greed would be shown to be even more pronounced.
Did you know that it is illegal in most states for a dental lab to deal directly with the public? Some latitude is allowed for labs to take shades for restorations which are prescribed by dentists, and some very few states have denturist legislation, whereby people can get lower cost dentures.
Dentistry is a closed shop. Break a tooth out of a denture and a dental lab can’t help you without a dentist’s prescription. The lab may charge a dentist $50 for the single tooth repair. How much does the dentist then charge the patient?
Your kid loses his retainer after orthodontic treatment. The lab bills the dentist for less than $45 for an average retainer. How much did the dental office charge the parents for the replacement?
Dental technicians are unregulated. Anyone can call himself a dental technician. Reputable technicians have tried for years to institute minimal standards for their profession, but to little success. The dentist lobby has blocked most of these attempts. Ask a dentist why.
The NADL has has an adjunct, the National Board for Certification, or NBC. It sponsors a voluntary certification process, which awards the title of CDT or Certified Dental Technician, to successful candidates.
Some states, such as Texas, require that dental labs in their state have at least one CDT in the lab operating in Texas. There are no broad requirements for all dental technicians in their state.
Did you know that there are no specific standards for US dentists who do their own lab work? I have seen the lab work of many dentists, few could meet the standards of the voluntary CDT program. Neither the states nor the state components of the American Dental Association seem interested in regulating dental technology as performed by dentists, nor establishing objective criteria for the regulation of dental technology.
Caveat emperator, let the buyer beware.
“The lab determined that the porcelain filed away in her mouth contained lead. “
It appears that the porcelain cap was filed in her mouth upon insertion and the filings contained lead.
Ironically, I think that China and the third and fourth world overall is recycling our own foreign electronic components.
Regular solder contains silver and lots of lead. It’s pretty common for the poor to cook it off of circuit boards to sell to those to refine it further for jewelery or whatever.
Good thing I'm alone; I wasn't as polite.
It's about time for a check up anyway. Looks like I'll have to ask just where the 10K+ of dental work I've had done over the past 4 years has come from. When they said the 'lab' was doing the crowns, it never occured to me that the damn lab might be in China. jeez...
