Effect of radio-frequency radiation from Wi-Fi devices on mercury release from amalgam restorations

Dental amalgam is composed of approximately 50% elemental mercury. Despite concerns over the toxicity of mercury, amalgam is still the most widely used restorative material. Wi-Fi is a rapidly using local area wireless computer networking technology. To the best of our knowledge, this is the first study that evaluates the effect of exposure to Wi-Fi signals on mercury release from amalgam restorations.

Field study on the mercury content of saliva

Authors: P.Krauß and M. Deyhle, K.H. Maier, E. Roller, H.D. Weiß, Ph. Clédon

Abstract: 20 000 subjects were enrolled in a large-scale field study to determine the concentration of total mercury in saliva. A statistical relationship was found between the mercury concentration in the pre-chewing saliva and chewing saliva, and the number of amalgam fillings. The mean number of amalgam fillings was 9 and the median mercury concentration was 11.6 μg/l in the pre-chewing saliva and 29.3 μg/l in the chewing saliva, which is considerably higher than reported in most previous publications. Extrapolation to the uptake of total mercury per week has shown that the provisional tolerable weekly intake (PTWI) value of the WHO is exceeded in at least 30% of the subjects.

An Introduction to Biological Dentistry

In using the term biological dentistry, we are not attempting to stake out a new specialty for dentistry but rather to describe a philosophy that can apply to all facets of dental practice and to health care in general: Always seek the safest, least toxic way to accomplish the mission of treatment, all the goals of modern dentistry, and do it while treading as lightly as possible on the patient’s biological terrain. A more biocompatible approach to oral health is the hallmark of biological dentistry.
