An evaluation of the marginal seal of amalgam using S.I.A.
The Selective Interfacial Amalgamation (S.I.A.) amalgam linear system was evaluated for its ability to reduce marginal leakage in freshly placed amalgam restorations. Leakage was evaluated in extracted and restored human molars which had been submerged in methylene blue dye for seven days at 37 C. The results shows a statistically significant difference (P less than 0.01) in the leakage of teeth restored using the S.I.A. liner and amalgam as compared to Copalite and amalgam restorations with the S.I.A. restoration proving to be superior.
