Introduction
Dental amalgams have been proven to a composition of an alloy of silver, copper, tin, and zinc combined with mercury which are dentally advantages when used (Wolff et al., 1983; Desmet et al., 1984; Shraim et al., 2011). ‘The Godfather of Amalgam’; Louis Regnart, added the mercury to solidify or strengthen a cement mix he made to make an amalgam. This mercury also assisted in preserving the cement mixture at liquid form to be used on human teeth (Eames, 1959). Then in 1959, the formula for the cement was again amended but with a reduced mercury-to-alloy mixture ratio (Eames, 1959). Later on copper replaced tin; the copper was introduced to strengthen the alloy and the copper was less probable to corrosion in comparison to the earlier …show more content…

Each element has its own toxicology profile and how these elements are useful to the human system (Klaassen, 2001). Dental amalgams deteriorate due to a number of causes, namely; mastication, vigorous teeth brushing, oral temperature increase and abrasion. When the dental amalgam is damaged it tends to release a mercury vapour or little pieces of amalgam which are ingested into the system with beverages or food (SCENHIR, 2007; Roberson et al., 2006; Huggins, 1992). The amount of damage dental amalgams can produced is based on the size, sensitivity of the patient to one of the elements in the amalgam, composition of the amalgam, the age of the amalgam and the surface area covered by the amalgam (Weiner et al., …show more content…

Mercury interrupts the immune homeostasis and the measles virus stimulates the release of cytokines which sparks the further damaging effects of the disease (Cohly and Panja, 2005). Environmental mercury does in fact altercate the disease pathogenesis of autism, such hypotheses have not been substantiated the fact but Cohly and Panja (2005) does endorse the fact. The data of the study of Cohly and Panja (2005) illustrates that Thimerosal in the mercury does have health effects of humans; Thimersol does at time exist in some bacterial or viral vaccines. One cohort study conducted by Andrew et al. (2004) ruled out the fact that Thimerosal leads to any kind of neuro-disorders. To clear up all this controversy of mercury containing Thimersol, vaccines and dental amalgams, the Institute of Medicine in Washington released a report to the Food and Drug Administration stating there is no correlation between dental amalgam, Thimersol and autism (IOM,

A little rate of the populace is hypersensitive to amalgam and there is likewise prove that it might assume a part in oral lichen planus, a by and large generous and moderately unprecedented turmoil.

Those who oppose infant vaccinations believe that they cause a host of chronic, incurable, and life threatening diseases. To start off with the most debatable issue which is that mercury found in vaccines as a preservative leads to autistic spectrum disorders especially since it is given to infants at critical developing periods. According to a study, mercury levels are decreasing in the blood after being given the shot, thus believing that vaccines containing thimerosal which is an organomecury compound are safe to use (Pichichero et al, 2000). According to a more thorough study , mercury is not leaving the body or disappearing but traveling to the brain and turning into inorganic mercuric chloride (Burbacher et al, 2005).In the US, the commonness

The Centers for Disease Control (CDC) estimated that 732,000 American children were saved from death and 322 million cases of childhood illnesses were prevented between 1994 and 2014 due to vaccination.” With these given statistics, Parents should be more than willing to vaccinate with all the lives saved in the years past. One main factor that makes the vaccines safe is the ingredients used. While used in large quantities, thimerosal, formaldehyde, and aluminum can be dangerous but scientist have lowered the dosage to a healthy form. Along with using safe ingredients, each vaccine has to be tested up to 10 years or more before they are licensed.

Thimerosal is an ingredient in influenza shots and is rumored to cause brain damage. This rumor was made popular by internet forums but the truth is, there is no evidence this chemical causes illness in humans and babies who are strictly breastfed come into contact with much greater amounts of thimerosal than are in vaccinations. Some chemicals used can be dangerous in large amounts, but are not harmful in the small amounts present in vaccinations (Bronfin

Dental erosion can take place due to chemicals that are exposed to our teeth from a selection sources, our environment and diet. These are known as extrinsic factors. Environmental factors involve constant exposure to acidic chemicals in fumes.[7] Factory workers are mainly affected by this for example, a case of dental erosion was reported in an individual who worked for over twenty years in the war industry. For at least 8 hours a day, this individual had inhaled and was exposed to chromic acid.[8]

The amount of mercury found in thimerosal was more than the amount approved by the FDA. Upon this discovery, the FDA made it mandatory for vaccine companies to either get rid of thimerosal or reduce the amount of it from the vaccines. In 2001 a comprehensive study by The Institute of Medicine concluded that there was not sufficient evidence linking mercury in vaccines and neurodevelopmental disorders. Thimerosal is not used in most vaccines today except for a few influenza vaccines.

Modern medicine provides people with the ability to protect themselves from the world’s most fatal diseases. Merely a century ago, it was not uncommon for a child to die as a result of diseases such as polio, pertussis, and tuberculosis. Today, it is highly unlikely for a person to contract these diseases, let alone die from them. However, refusal of vaccinations has been increasing throughout the years due to the anti-vaccination movement. This movement declares mandatory vaccines unconstitutional and vaccinations overall as the cause of autism.
