Abstract
Purpose:
As our society develops IT technology, such as the Internet, the number of patients with unspecific symptoms whose complaints include stiff shoulders, sore back and so on has increased. The majority of these patients who come to dental clinics expect to get better by improving their occlusal conditions. In some cases, however, the treatment does not work as well as expected or the symptoms reoccur again and again until we change dental material in the patient’s oral area. It has been acknowledged that some dental materials cause an allergy when it dissolves and is absorbed. The author would like to report the possibility that some dental material also acts as an antenna receiving electromagnetic wave in the environment causing the symptoms listed above, and how to deal with these problems.
Method:
First, cellular phones or computers were put close to the subjects in order to apply electromagnetic wave. Second, electromagnetic wave was again applied to the subjects who showed the symptoms such as dizziness, sense of equilibrium disorder, numbness of hands, or dyspnea while putting the same kind of dental material as the subjects had in their mouth close to them. Third, in case of the subjects, whose symptoms were worsened, Bi-Digital O-Ring Test (OMURA. Y.1977-2004/BDORT was done with the conductive stick put on the subjects dental material. The dental materials that were found to weaken the subjects’ grip strength were removed under die protection of rubber dam and it was found that the symptoms disappeared or improved. Finally, all kinds of dental material were put close to the subjects and BDORT was performed while applying electromagnetic wave. Then the subjects’ dental material was switched to one which strengthened the subjects’ grip in the test. When an adhesive such as cement was needed in switching, the material and the adhesive were put together to do the test.
Result and Discussion:
It is suspected that dental material such as metal is involved with disease caused by electromagnetic wave. It has been generally acknowledged that disease caused by dental material was triggered when it dissolves and is absorbed. It has been also reported that electromagnetic wave from dental material may cause these symptoms. The finding, however, shows that specific dental material acts like an antenna and receives electromagnetic wave, which causes unpleasant symptoms. It was also found that the disease could be avoided by taking out the material and that BDORT is very useful to find which material should be removed and which new material should be used in its place.
Conclusion:
BDORT is useful in finding the dental material that receive electromagnetic wave and cause disease and which materials can be safely used as a replacement.
