| Popis: | Mercury levels were determined in the urine of seventy dentists and their assistants engaged in full-time restorative dentistry. Twenty nondental personnel were used as controls. The dental personnel were divided among six separate clinics having two basic designs. Ten morning specimens of urine were collected from each subject over a period of 2 weeks, and mercury was determined in duplicate in each specimen by atomic absorption spectrophotometry. Mean urinary mercury values, ranging from 3 to 17 μg per liter and 5 to 124 μg per liter, were obtained for the controls and dental personnel, respectively. Compared to the controls, 65.7 per cent of all personnel and the over-all data from three clinics showed significantly elevated levels of urinary mercury. In one clinic consisting of twelve dental units in one large room, all personnel showed significant elevations in urinary mercury. A comparison of restorative work done in a given period with the mean urinary mercury value for each clinic suggests that, with regard to mercury hygiene, the single-large-room design is less desirable than a situation in which individual dental units are located in separate but adjoining rooms. |
