Investigation of Dental Luting Cement Solubility as a Function of the Marginal Gap

摘要

The purpose of this study was to investigate the rate of cement solubility as it relates to the degree of marginal opening. Both a static and dynamic environment was used to evaluate the influence of diffusion and convection on cement solubility. Dental cements used in fixed prosthodontics have the primary purpose of luting or sealing the cast restoration to the prepared tooth. A permanent luting cement should have high strength, low film thickness, be non-irritating to the dental pulp, and have low solubility. A critical property of luting cement is its solubility in oral fluids. If the cement dissolves at an unacceptably high rate the tooth is susceptible to recurrent caries and the retention of the cast restoration can be compromised.
