Weighing new evidence against potential neurotoxicity The new behavioural study among dentists by Ritchie et al , reported in this issue of Occupational and Environmental Medicine , found no adverse effects associated with low exposure to mercury in urine, hair, or nails, that assess subjective symptoms as well as more objective measures of psychomotor performance. The new study laudably addresses the World Health Organisation's request for chronic Hgo exposure studies that are useful in… 

Longitudinal analysis of the association between removal of dental amalgam, urine mercury and 14 self-reported health symptoms

It is suggested that mercury exposure from amalgam fillings adversely impact health and therefore are a health risk, and the use of safer alternative materials for dental fillings should be encouraged to avoid the increased risk of health deterioration associated with unnecessary exposure to mercury.

Neuropsychological Effects of Mercury Exposure Among Dentists in Monastir City.

Increased levels of urinary mercury observed in dentists suggest that exposure to mercury vapour emissions adversely affects dental professionals, therefore prevention measures should be strengthened, with a special medical supervision program of dentists exposed to mercury vapor vapours should be implemented.

In this issue, Dye and coworkers present recent data on urinary mercury (U-Hg) in a representative sample of about 1600 US women aged 16–49 years from the NHANES study of 1999–2000.

Amalgam studies: disregarding basic principles of mercury toxicity.

A number of studies are methodically flawed drawing inaccurate conclusions as to the safety of dental amalgam, considering the newest findings on mercury toxicity and metabolism.

Are mercury amalgam fillings safe for children? An evaluation of recent research results.

Two recent clinical trials on the safety of amalgam fillings in children found no evidence of harmful effects from mercury-containing dental fillings after following children for 5-7 years. This

A systematic Review and Meta-Analysis of Mercury Concentrations in Blood, Urine, and Area Air Samples among Dentists in Iran

The results of this study demonstrated that the 95% CI of the mean concentration of mercury in the urine samples of Iranian dentists is higher than the standard limit, and dentists should be examined annually in terms of urinary mercury concentration.

Cognitive Dysfunction Associated with Elemental Mercury Ingestion and Inhalation: A Case Study

It is argued that mercury toxicity is more likely than not to have been a factor contributing to the patient's cognitive dysfunction.

Maternal dental history, child's birth outcome and early cognitive development.

Overall, dental care, including amalgam fillings, was not associated with birth outcomes or language development, but having X-rays taken during pregnancy was associated with slightly increased odds of having a term, low-birthweight baby.

The Severity of Autism Is Associated with Toxic Metal Body Burden and Red Blood Cell Glutathione Levels

A significant positive association is demonstrated between the severity of autism and the relative body burden of toxic metals and the level of RBC glutathione.



Neurobehavioral effects from exposure to dental amalgam Hgo: new distinctions between recent exposure and Hg body burden

New distinctions between subtle preclinical effects on symptoms, mood, motor function, and cognition were found associated with Hg body burden as compared with those associated with recent exposure.

Chronic neurobehavioural effects of elemental mercury in dentists.

The results raise the question as to whether the current threshold limit value of 0.050 mg/m3 (TWA) provides adequate protection against adverse effects of mercury.

The aim of the present work was to clarify the question of preclinical changes of Hg intoxication (“micromercurialism”) in man and to detect these disorders on chloralkali plant workers who had been exposed to mercury for more than 7 years.

Chronic low-level mercury exposure and neuropsychological functioning.

Chronic subtoxic levels of inorganic mercury appear to produce mild changes in short-term nonverbal recall and heightened distress generally, and particularly in categories of obsessive compulsion, anxiety and psychoticism, without alterations in general intellectual functioning, attention, verbal recall, and motor skills.

Effects of occupational exposure to mercury vapour on the central nervous system.

Dose-response calculations showed weak but statistically significant relations between symptom prevalence and current mercury concentrations in both blood and urine and indicate a slight mercury induced effect on the CNS among the chloralkali workers.

Subjective symptoms and psychological performance of chlorine-alkali workers.

Strain caused by three-shift work was a possible cofactor for other increased subjective symptoms, namely, for sleep disorders, fatigue, and confusion.

Sodium 2,3-dimercaptopropane-1-sulfonate challenge test for mercury in humans: II. Urinary mercury, porphyrins and neurobehavioral changes of dental workers in Monterrey, Mexico.

The easily performed DMPS-mercury challenge test is useful for monitoring dental personnel for mercury vapor exposure and is a better indicator of exposure and renal mercury burden than is the mercury level measured in the urine before DMPS is given.
