Avaliação de uma técnica de compactação do gesso odontológico como alternativa para a correta relação água/pó

The water-powder relationship is essential to achieve a proper performance of gypsum for prosthetic purposes. ideal measure can be obtained with balance, but this clinically unavailable, once it timeconsuming. A powder-compacting technique using volume measurement suggested in order substitute the balance. consists meter within bag. While operator holds one hand, palm other hand pressed over surface meter, supported by ventral aspect fingers that pressing. This procedure based upon three compactation movements each operator, then counting average compacting sample. Each ten operators repeated six times procedure, and final was defined. resulting samples were weighted, statistical analysis showed significant differences (p = 0,006) among operators.
