			LEad contaminated crowns from china Recently, NADL was contacted by a dental patient in Ohio who has documentation of lead contamination in her dental restoration. The affected patient, a senior citizen, received a three-unit dental bridge from her dentist in Ohio. After having an adverse reaction to her dental work, and having it removed, the dentist disclosed that the prescription was sent to a dental laboratory in China. The patient then had the restoration sent to a chemical laboratory for analysis. The documentation of the dental material analysis of this patientís restoration showed unsafe levels of lead in the porcelain on the restoration. This case has attracted the attention of an Ohio television reporter who was already working on a story about offshore dental laboratory work. As part of the reporterís investigative research for the story, the TV station ordered a series of crowns from several offshore dental laboratories. One of those restorations contained 210 parts per million of lead in the materials. The U.S. Congress, in response to the toy recalls in 2007, lowered the acceptable levels of lead in toys to 90 parts per million. The testing of these restorations for the reporterís investigation was conducted by a chemical research laboratory in Ohio and, at the suggestion of NADL, at the Boston University School of Dental Medicine. In addition to the documentation of lead, the chemical analysis revealed the restoration contains traces of radioactive isotopes. The National Association of Dental Laboratories believes that every dental patient has a reasonable expectation that the dental restoration placed in his or her mouth is safe, regardless of where it is manufactured. Therefore, in an attempt to provide the necessary documentation for disclosure as well as to document competency, the NADL strongly supports the following: At least one Certified Dental Technician (CDT) in each dental laboratory. All dental laboratories register with either the U.S. Food and Drug Administration or an appropriate state governmental agency. Written documentation of all materials included in a final restoration and the point of origin (country and laboratory) where the restoration was manufactured. Each of ther above items be documented in the patientís record. Read more Read more: ABC NEWS Komo 5 NEWS SeaBrook Dental Laboratory has been certified by ACDLA
