Dental Amalgam, Mercury Emission.Abstract
The authors studied the mercury vapor emission of the conventional amalgam alloy and high copper alloy with the purpose of verifying the effect of burnishing, varnish use and tints. The dosages of mercury were made after amalgam condensation using an atomic absorption spectrophotometer with a small chamber to receive the mercury vapor. In our experiments the highest values of emission were observed soon after condensation and up to 6O minutes; after this period the level of emission decreased with lime. In the high copper alloy the initial values for mercury vapor emission are higher than the one observed for conventional alloys. In carved amalgam the mercury vapor emission is higher when compared with burnished amalgam with or without cavity varnishes, and with those which were only carved, condensed after cavity varnish application.
