dc.description.abstract | Mercury release from dental amalgams has generated considerable concern in recent years and is the subject of this study. Specimens of one admixed high-copper amalgam (Contour), one lathe-cut low-copper amalgam (SDI), and a new tin- and copper-free amalgam claimed to be non-mercury-releasing (Composil) were evaluated for release of mercury when incubated in purified water at 37°C. Measurement of mercury was done by cold-vapor atomic absorption spectrophotometry, and the amount released was expressed as μg/cm2/24 hr. Study was conducted over a four-week period. Results show that Contour and SDI released similar insignificant amounts (mean release of < 0.1 μg/cm2/24 hr) compared with Composil (mean release of 41.0 μg/cm2/24 hr). The difference in release by Composil compared with that by Contour and SDI is highly significant (P < 0.001). The implications of chronic release of mercury from dental amalgams are discussed. Long-term release studies are in progress. © 1989. | |
