Marginal Sealing Quality of IRM and Cavit as Assessed by Microbial Penetration.
Abstract
Two of the most frequently used temporary materials are a polymer-reinforced zinc oxide-eugenol intermediate restorative material (IRM) and Cavit, a premixed noneugenol paste containing zinc oxide, calcium sulfate, zinc sulfate, glycol acetate, polyvinyl acetate, polyvinyl chloride acetate, tri-ethanolamine, and red pigment. The ability of Proteus vulgaris to penetrate the seal provided by IRM and Cavit was investigated by using an in vitro model system consisting of extracted molar teeth embedded in acrylic. All temporaries were allowed to set for 24 hours next to a cotton pellet containing Camphorated Monochlorophenol (CMCP) or saline. IRM which had set next to CMCP provided a significantly better seal after 3 weeks than IRM which had set next to saline, or Cavit which had set next to CMCP. Cavit placed next to saline was the least effective seal.
