Follow on Google News | Four Out of Five Dentists Concerned About Lead in Dental CrownsDental labs may be turning out dental prosthetics that are contaminated with lead, allege recent news reports. In a Wealthy Dentist survey, four out of five dentists said that this issue definitely requires more research.
News reports surfaced earlier this year of lead in dental restorations. Though the scope of this potential public health crisis is not yet clear, shockingly high levels of lead have been discovered in dental crowns. Chinese dental labs were initially blamed for the contamination. Recent evidence suggests the problem may be even more widespread than previously thought, as dental products from labs in the US and Thailand have also tested positive for lead. Authorities agree that there is no benefit to having lead in dental work. (In fact, the acidic environment of the mouth may encourage lead to leach out of the dental restoration and into the patient's bloodstream.) "Lead in dental casting alloy? Outrageous!" exclaimed a Colorado dentist. "There is no sound reason to have lead in dental restorative materials," agreed a Washington dentist. "There is no place for lead in dentistry," declared a Colorado orthodontist. Though the exact risks of lead in dental work are not known, lead itself is a known toxin. "Lead is bad for the health," said an Ohio dentist. "Highly synergistic toxicity, especially with mercury," warned a Wisconsin dentist. Everyone agrees on the need for additional research to determine the scope of this problem and prevent future problems. "We should test products and eliminate sources of contamination," Some dentists downplay the threat. "This is no more dangerous than leaded crystal or the lead in fine china, but research is warranted," said a Texas dentist. "Recent articles have debunked the worry over the amount of lead in the 'farmed-out' crowns. Still, we need to monitor that work," agreed a California dentist. "We still don't know if this is a widespread problem or not," said Jim Du Molin, dental continuing education guru and founder of dental management resource The Wealthy Dentist. "This could be a huge public health scandal. Or it could be a minor issue, easily corrected. What's so frustrating right now is not knowing which it is!" http://www.thewealthydentist.com/ # # # Visit http://www.thewealthydentist.com for more surveys in the areas of dental implants, cosmetic dentistry, edation dentistry, wisdom teeth, braces, and dentures.
