CHAMPIONSGATE, Fla., Dec. 19, 2018 /PRNewswire/ — Two new studies associating dental amalgam fillings with pregnancy risks confirm action is urgently needed to protect babies from the known risks of mercury, according to the International Academy of Oral Medicine and Toxicology (IAOMT). A growing number of countries have taken measures to prevent the placement of dental amalgam “silver” fillings in women and children because it contains approximately 50% mercury. However, dental amalgam is still used widely in the United States with no restrictions for these or other susceptible populations.
One of the new studies by researchers in Norway involved over 72,000 pregnant women with data on the number of teeth containing dental amalgam fillings. Lars Bjorkman and his co-authors discovered a “statistically significant association between the number of teeth filled with dental amalgam and the risk of perinatal death.” Their research was published earlier this month in the peer-reviewed journal PLOS One.
Another new study by researchers in Egypt investigated the pregnancy outcomes, urinary mercury levels, and blood antioxidant activities of a cohort of 64 pregnant dental staff and 60 other pregnant women. They found that pregnant dental staff “suffered higher odds of developing spontaneous abortion and pre-eclampsia and giving birth to babies smaller for gestational age.” The study appeared earlier this year in the peer-reviewed medical publication The International Journal of Occupational and Environmental Medicine.
