Research on Dental Amalgam
The World Health Organization (WHO) has listed dental amalgams as among the products containing mercury which it describes as “one of the 10 groups of chemicals of major public health concern.” WHO describes mercury on its website as a “naturally occurring element that is found in air, water and soil” and is “harmful to humans, especially pregnant women, infants and children.”
Gordon HP, Cordon LD: Reduction in mercury vapour levels in Seattle dental offices. J Dent Res Abstract 1092 57A:347, 1981. Female dentists had a higher rate of spontaneous abortions than a control of female medical personnel or the rest of the population. Peri-natal mortality rate for the female dentists was significantly higher than for the rest of the population. (19.5/1000 compared to 7.5/1000 Connections between oral and systemic health
Nylander et al. 4th Symposium Epidemiology in Occupational Health. Como Italy September 1985. In a study of 9,241 people 3454 were male dentists 1125 female dentists, 4662 female dental nurses. A two-fold increased risk of glioblastomas for the dental personnel compared to the rest of the population.
Ship II, Shapiro IM: Mercury poisoning in dental practice. Compendium Continuing Education 4: 107-110, 1983. 298 dentists. 30% of the high mercury dentists had polyneuropathies. No polyneuropathies were detected in the control group. The high mercury group had mild visuo-graphic dysfunction; they also had more symptom-distress than did the control group. The findings suggest that the use of mercury as a restorative material is a health risk for dentists.
Boyd et al. The American Physiological Society Nov 1991. Mercury from dental “silver” tooth fillings impairs sheep kidney function.
M.J. Vimy, Y. Takahashi, and F.L. Lorscheider. Am.J. Physio. 258 (Regulatory Integrative Comp. Physiol. 27) R939-R945. 1990. Maternal-fetal distribution of mercury (203 Hg) released from dental amalgam fillings. All tissues displayed Hg accumulation. Highest concentrations of Hg from amalgam in the adult occurred in the kidney and liver. In the fetus the highest amalgam concentrations appeared in the liver and pituitary gland. Dental amalgam usage as a tooth restorative material in pregnant women should be reconsidered.
NHMRC (National Health and Research Council – Australia). Endorsed 24 October 2002. Dental Amalgam – filling you in. During pregnancy, placement of new amalgam fillings or removal of old ones is not recommended, because the levels of mercury in the blood tends to rise in these situations. The mercury can cross the placenta and enter the bloodstream of the fetus. Women who are breast feeding should also avoid have amalgam fillings inserted or removed. Amalgam is now generally avoided for filling children’s teeth. Growing children tend to be more sensitive to the effects of exposure to any chemical substance in their environment. People with kidney disease may be more concerned than others to minimize exposure to mercury. If you decide to have amalgam fillings replaced, your exposure to mercury can be reduced by using a rubber shielding device called a “dental dam” and having extra suction during the removal. Dentists can also cut away rather than drill out the amalgam filling, to help reduce exposure to mercury.
As you can see from the graph above. There may be little evidence to support that fluoridated water actually helps prevent tooth decay. Tooth decay rates have fallen globally since 1970 regardless of fluoridated water. Perhaps there are other factors involved.
Menoyo 2005; de la Sota 1997; Rigalli 1995, 1990. Not only have researchers confirmed that spikes in blood fluoride levels increase glucose levels, but they have found that the effect occurs at just 95 ppb – less than 10 times the fluoride level that can enter blood after fluoride-gel treatment, and exceeded on a daily basis by some children using fluoride toothpaste.
Zakrzewska 2002, 2006. Polish researchers reported that low levels of fluoride can damage sperm in ways that could impair male fertility. Links between oral health and systemic health.
Shahed 1986; Whitford 1987 .Researchers funded by the National Institutes of Health (NIH) reported that the toxic effects from short-term spikes in blood fluoride levels are not limited to the kidney. It is conceivable that normal ingestion of F following an APF application could alter several metabolic processes.

Research into Breathing Dysfunction
Dr Adelola et al. from the Department of Otolaryngology at Limerick University Hospital in Ireland investigated the effectiveness of the Buteyko technique on nasal symptoms of patients with asthma. Small clinical study of Buteyko Method at Limerick Regional Hospital shows 70% reduction of Rhinitis in Asthma
NIH Study: Buteyko breathing technique improvements in asthma symptoms and reductions in reliever medications. A report by the Agency for Healthcare Research and Quality, AHRQ, for the United States Institute of Health (NIH) finds Buteyko delivers substantial reductions in symptoms and medication usage for asthmatics.

Buteyko endorsed by British guideline on the management of asthma
The British Guideline on the Management of Asthma 2008 grants permission for British health professionals to recommend Buteyko, stating that the method “may be considered to help patients control the symptoms of asthma”. The guideline also grades clinical research on Buteyko with a ‘B’ classification – indicating that high-quality supporting clinical trials are available.
