An 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 type I zinc phosphate cement solubility as it relates degree marginal opening. Standardized test samples were constructed that would simulate clinically relevant gaps 25, 50, 75, and 150 microns their subsequent lines. divided into two phases. Phase 1 evaluated effects simple diffusion on in a static environment, whereas phase 2 investigated convective forces dissolution dynamic environment. Both studies demonstrated no significant difference for 25-, 50-, 75-micron groups. 150-micron groups both studies, however, an increase dissolution. results should not be compared because different methodologies used.
