“In contrast to the wealth of investigations on pulp reactions to filling materials, very little can be found on the reaction of gingival tissues to filling materials beyond the statement that overhanging margins of fillings produce gingival disease.”
“This subject has been well reviewed by Schriever and Diamond who also gave a considerable biography. However, while it is well known that pain occurs as a result of electrolytic activity in the mouth, it is thought that a clear explanation of how pain occurs has not yet been given. The object of this paper is to try to give such an account.”
“A number of histological and spedrographie studies have been made of the problem of resorption of mercury from dental silver amalgam fillings. In view of the somewhat contradictory results, the authors have studied this problem using radioactive mercury.”
“The combination of symptoms referable to the pyramidal system, anterior horn cells, and lower brain stem constitutes the syndrome of amyotrophic lateral sclerosis. The literature contains many case reports of this syndrome in which varied etiologic factors have been determined. Wechsler and associates1 analyzed 81 cases of amyotrophic lateral sclerosis and listed dietary deficiency and inflammatory, vascular, and toxic processes as etiologic factors. This clinical symptom complex has been noted following gastrectomy2 and polyarthritis,3 and in triorthocresyl phosphate poisoning.4 It has recently been considered an atopic-stress disorder, and some improvement has been obtained by the use of adrenocortical extracts.5 Cord tumors, syphilis, and arachnoiditis may also produce this syndrome. It becomes obvious that the physician in his evaluation of such a symptom complex must seek the clue to the etiology by a careful and detailed search into the patient’s occupation, contacts, illnesses, and injuries, since…”
“A paper by us entitled ‘Adverse Mercurial Reactions in the Form of Acrodynia and Related Conditions’ was published in March, 1951. Although written in 1949, its publication was delayed. Since that time additional data have been accumulated and at least fifty relevant publications have appeared in the literature.”
“Electrical phenomena in oral cavities have been described and discussed in many papers published between 1878 and the present time. Solomon, Reinhart, and Goodale abstracted the 24 most important papers published before June, 1933.”
“…it may be dangerous to inject a serum containing merthiololate into a patient sensitive to merthiolate.”
“The symptoms of chronic mercury poisoning are erethism, tremor and stomatitis. Seventy-two men in a thermometer workshop and 11 in a chemical works making pharmaceutical compounds of mercury were examined. Mass observation suggests that the thermometer workers suffered from mild chronic mercury poisoning, whereas little abnormality was seen in the older group of chemical workers. Atmosphere and urine estimations showed that the thermometer makers were excreting up to 10 times as much mercury in a day as could possibly be absorbed from the atmosphere.”
This paper is divided into two parts. The first part reports the determination of the amounts of mercury vapor found in the air of various ventilated and unventilated laboratories at the National Bureau of Standards and elsewhere. The new optical mercury-vapor detector devised by Woodson and produced by the General Electric Co. was used to secure this information. The concentrations found ranged up to 70 micrograms of mercury per cubic meter of air. Various sources of mercury vapor are described, as well as some measures taken to lower the concentration.
“Merthiolate should never be given in amounts exceeding 0.15 gram per 100 lbs. of body weight; nor more frequently than once in 10 days. This drug should not be used if there is evidence of active hemorrhagic nephritis.”
