dc.description.abstractAn in vitro study was carried out on 60 human pre- molar teeth to study the sealing efficacy of Glass Ionomer, Silver amalgam, Composite resin and cavity varnish in Class V cavities. The filled specimens were thermocycled (4 degrees C +/- 2 degrees C and 60 degrees C +/- 2 degrees C) and subjected to Radio Isotope penetration tests. S35 was used as a tracer and autoradiography for detecting the microleakage. The extent of penetration of S35 in case of each material was assessed. No material was found to completely seal the cavity, however, Glass Ionomer could minimise the microleakage. Amalgam restorations exhibited gross microleakage which reduced to a great extent after application of cavity varnish. Composite resin was found to be superior to Silver amalgam in controlling microleakage.en_US
