Black's class I classic cavity preparations were completed in 440 extracted, intact human premolars and restored with two silver amalgams and five different base materials with and without cavity varnish, which resulted in 20 combinations. A standard fluorescent dye test was performed and the percentage of marginal leakage recorded after storage for 7 days, 3 months, and 1 year in 1% NaCl at 20 degrees C. The results were computed by use of a linear logistic statistical analysis with a critical… CONTINUE READING
