โœฆ Synopsis

Zinc release from a range of dental restorative materials was measured in the absence and presence of dentin over a 2-week period. The presence of dentin was designed to simulate the residual dentin in vivo. There were considerable differences in both the levels and pattern of zinc release for the different materials. In several cases the concentrations exceeded the level which has been reported cytotoxic to cells in culture. With dentin, little zinc passed into solution, and high concentrations were measured in the dentin. This may explain the discrepancy between in vivo toxicity tests using zinc-containing materials and previous in vitro tests which have not included dentin in the test system. 148, 767-773 (1967).

The in vitro Zn release from tricalcium phosphate containing Zn (ZnTCP; 0.63, 6.17, and 12.05 Zn w/w%) was investigated. The rates of release from ZnTCP powders were measured in 25 mL of simulated body fluid (SBF) containing 10 mg/100mL Ca (SBF/H), 5 mg/100mL Ca (SBF/L), or no Ca (SBF/-) at pH 7.25,

Little is known of the release of trace elements in vivo from dental implant materials. Conflicting data have been reported in the literature as to the levels of trace elements released and their potential consequences, mainly because of sampling and analytical methodological errors. In this study m
