Evidence that Mercury from Silver Dental Fillings May Be an Etiological Factor in Reduced Nerve Conduction Velocity in Multiple Sclerosis Patients
نویسندگان
چکیده
Seven multiple sclerosis subjects had their silver dental fillings (amalgams) removed which contained approximately 50% mercury. A visual evoked response (VER) test was performed before amalgam removal. Approximately six months after amalgam removal a second VER test was performed on all subjects, and the latencies of the VER decreased significantly. The mean latency of P1 for the right and left eye combined decreased by 23.1 milliseconds (P=0.011) and N1 of the right and left eye combined decreased by 31.7 milliseconds (P=0.026). It was hypothesized that mercury from dental amalgam was an etiological factor in reduced nerve conduction velocity in MS subjects.

Background: Dental amalgam, a mixture of approximately 50% mercury with silver, tin, zinc and copper in varying ratios, is a major source of mercury pollution in the general population not occupationally exposed. The toxicity of mercury is enhanced because it is so readily absorbed, with around 90-100% of mercury vapor being absorbed through the oral mucosa. The aim of the current study is to e...

According to the World Health Organization (WHO), factors such as growing electricity demand, ever-advancing technologies and changes in social behaviour have led to steadily increasing exposure to man-made electromagnetic fields. Dental amalgam fillings are among the major sources of exposure to elemental mercury vapour in the general population. Although it was previously believed that low ...
