ABSTRACT
The object of this paper is to evaluate the marginal filtration occurring between restoration/teeth in cavities filled with silver alloy when using different cavity varnish and adhesives. In 50 teeth removed as a result of decay, cavities were prepaired on vestibular faces and were divided into 5 equal groups Group A with no caviti varnish; Group B two coats of a linkin agent (Scotch Bond 3M); Group C an amalgam liner base (Voco); Group D; two coats of copal varnish Group E an amalgam bond base (Carl San Remo, Germany). All groups were filled with a silver alloy. The teeth were inmersed in a fuchsin solution at different temperatures (17.37 degrees C and 50 degrees C) for 20 minutes. Longitudinal cuts were made for visualization under a stereoscopic magnifying glass. Each group was observed by five odontologists and was classified according to four categories Grade I no filtration Grade II less than 1/3 wall filtration; Grade III more than 1/3 wall filtration; Grade IV filtration in walls and floor. Teeth with pulp filtration were discarded. Total and percentage values were determined for each analysed group. The results revealed that Group A 100
