Anesthetic exposure and health of dental personnel.
Department of Anesthesia, Stanford University, Stanford, California 1980 Jan; :1-13
The results of an epidemiologic survey on health hazards in dentistry (SIC-8021) were summarized. The project was designed to determine possible health hazards to dentists and assistants; the contribution of anesthetic gases, particularly nitrous-oxide (10024972), to health problems; the effects of cigarette smoking on fetal viability and abnormalities; and the fetotoxic effects of anesthesia exposure during pregnancy. The 30,650 dentists and 30,547 assistants surveyed by mail were grouped according to anesthetic exposure. Increased rates for liver disease, kidney disease, an neurological disorders among male dentists were found. In wives of male dentists exposed to anesthetics, a 1.5 fold increase in the incidence of spontaneous abortion was noted. For dental assistants a 2.3-fold increase in spontaneous abortion occurred. Chronic exposure to nitrous-oxide was associated with an increase in adverse response. Surgical exposures of pregnant women to anesthetics resulted in a 57 percent fetal loss in women exposed during the first trimester, but no increase in congenital defects among the offspring. A 27 percent increase in spontaneous abortion was found for dental assistants who smoked and 21 percent increase occurred in smoking wives of dentists. Congenital abnormalities occurred in 34 percent of the babies born to dental assistants who smoked.
