摘要: In this two-part in vitro investigation, apical leakage was electrochemically analyzed teeth with different thicknesses and compositions of dental amalgam. part 1, the apices 10 each were filled zinc-containing amalgam to a depth 1 mm or 3 mm. Part 2 consisted filling following varnish application, zinc-free amalgam, varnish. All 30 Measurements sample obtained at 24-h intervals for days. A two-way analysis variance showed that significantly reduced as compared 1-mm filling. Leakage when used regardless composition.
