ABSTRACT

The amalgam has beco me the best filling material for posteriorteeth in Class 1 cavities, because is easyto handling. The objedives were to evaluate and compare the degree of microleakage, adaptation and porosity of omalgom pocked by manual and mechanical methods. 60 premolars decayfree were used, which were class 1 occlusal cavities, and then 30 teeth were filled by manual method and 30 teeth by the mechanical method. Then token too mochine thermocycling for 500 cycles at a temperatura of 55^oc and 10 ^oc. lt is varnished and placed in basic fuchsin for 12 hours. Finally the teeth were bucal-linguolly sedioned, ond onolyzed microscopicolly. Amalgams compactad by the mechanical method showed less number of dead spaces, better adaptotion ond less microleakoge than the compaded by the manual method. With mechanical compadion will produce a more uniform amalgam, better adapted to the covity wolls to ensure the success and longevity of the restoration.
