✦ Synopsis
Pregnancy outcome in women with work in dentistry was studied using various central health registries A total of 8157 infants born of dentists, dental assistants, or dental technicians in 1976 or 1982-1986 in Sweden were studied with respect to perinatal survival, low birthweight, and malformations and compared with all births The only deviating finding was that of a significantly low perinatal death rate Specifically, no increase in a risk for spina bifida was seen and the upper 95 % confidence limit for the risk ratio was 2 1 A study was also made of hospitalized spontaneous abortions in women with these occupations in the years 1980-1981 No significant deviations from expected values were found In a small study of only 78 such pregnancies in 1964-1965, no increase in spontaneous abortion rate was seen Only one infant was malformed (anencephaly): both its parents worked as dental technicians None of the mothers of 220 infants with a neural tube defect born in 1965-1967 in Sweden was a dentist We find no indications that this occupation represents a significant reproduction hazard at the present time in Sweden.
