16 USPHS Sets Standard/ Determines Amalgam Mercury A Risk To Patients!


Now the question becomes: ''Are the State Boards of Dentistry
fulfilling their statutory obligation to protect the public health,
safety and welfare regarding exposure to mercury from amalgam dental
fillings?'' The answer is derived from awareness of the 1994 United
States Public Health Service (USPHS) determination: ''Thus, both MRLs
are below estimated exposure levels from dental amalgam.'' [USPHS,
ATSDR. Toxicological Profile for Mercury: Update. TP-93/10, page 125.]

In this document, the USPHS established its ''Minimal Risk Level
(MRL)'' for chronic and acute exposure to mercury vapor for the
general population (as distinguished from the 40-hours per week
exposure for healthy adult workers limitation of the OSHA Workplace
Standard). The chronic exposure MRL is 0.014 mcg Hg/m3 air, which the
USPHS calculated to equal 0.28 mcg Hg/day intake; while the acute
exposure MRL is 0.02 mcg Hg/m3 air, which translated to 0.4 mcg Hg/day
intake. The USPHS made their comparison to the conservative dental
estimates of daily intake of amalgam mercury, which were found in the
1993 CCEHRP document. The amalgam mercury daily intake determined by
medical experts exceeds USPHS MRLs even more.

The USPHS Standard is not an opinion, a ''committee consensus,'' or
even open to interpretation! It is a United States Standard for the
general population! Thus, the United States Government has determined,
and ruled, that the continual exposure to mercury from amalgam
fillings is not without risk to patients. It is, therefore, the
statutory obligation of State Boards of Dentistry to inform the
citizens and dentists of their state of this risk! Further, the
previous ''consensus reports'' from sub-units of USPHS, such as the
Food and Drug Administration and the National Institutes of
Health/National Institute of Dental Research, have now been superceded
and rendered obsolete.
