[The "dental amalgam syndrome" - an environmental somatization Syndrome? A comparison between chronic carbon monoxide intoxication and illness related to dental amalgam].
In 1940, during World War II, restrictions in import of petroleum products to Sweden necessitated the use of producer gas in motor traffic. In the following years, the incidence of acute carbon monoxide intoxications raised steeply. However, many patients with minor but longstanding exposition to producer gas exhibited a neurastenic syndrome (fatigue, headaches and vertigo) thought to be specific. In Stockholm, an epidemic of this syndrome can afterwards be traced to the personal conviction of an internist who also had an important influence on various authorities, leading to a forceful campaign to the public about the dangers of using producer gas. After some years, the frequency and even the existence of a chronic carbon monoxide intoxication was called in question and at the end of the war that diagnosis lost its actuality. In Sweden, oral galvanism attributed to dental amalgam was discussed in mass media in the 1970s, not least by evidence given by some well-known personalities. In the 1980s, the frequency of illness attributed to dental amalgam increased to an important epidemic. The question of the dangers of mercury released from amalgam fillings is still an important issue of debate among dentists and physicians, although the majority remains sceptical. Also medical authorities have found little evidence of the importance of dental amalgam toxicity. A patients organisation, Tandvårdsskadeförbundet, seems to have played a significant part in the acceptance of the syndrome among laymen. Thus, various psychosocial factors seem to have played a role in both syndromes which could thus be conceived as environmental somatization syndromes.
