Abstract
The image analyze system was applied to determine the efficiency of six amalgamators counting the ratio of amalgam alloy particles in a base material.An equal weight(0.2g)of the alloy and clay were mixed for 2 to 120 seconds, and the digital image of cross-section of the mix was taken by a CCD-TV-camera under a microscope.The image was filtered and processed at three densities before the measurement.Accurate re-producibility of the ratio of mixed part was obtained by this system.The results indicate that several factors affect the mixing efficiency of amalgamator besides the frequency.
