RESUMO
Potassium aluminum sulfate, aluminum chloride, and 8% racemic epinephrine did not demonstrate practical differences, although potassium aluminum sulfate produced fewer inflammatory changes than the other agents. 2. It appears that factors other than the chemical agent (e.g., physiologic differences in patients) may play a role in the amount of gingival inflammation induced. 3. Additional studies using a larger sample size and an untreated control site should be undertaken.

SEM studies indicate that the control alloy, Minigold, WLW, and Litecast metals presented similar results in relation to marginal fit when proper techniques are followed. Clinical evaluation based on the criteria of gingival irritation, patient sensitivity, and abrasion demonstrated no statistically significant differences between the casting alloys tested and the control. The control alloy had significantly fewer restorations with tarnish and corrosion than either WLW or Litecast. There was no significant difference between the control alloy and Minigold in terms of tarnish and corrosion.
