Evaluation of a dental amalgam alloy containing the fluoride additive stannous hexafluorozirconate

Weaver, Richard G., 1939- January 1973 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / This study was designed to evaluate a dental alloy containing stannous hexafluorozirconate at 0.5 percent by weight, to determine how the fluoride additive might affect the physical properties of the alloy and the clinical performance of the amalgam restorations. Using established methodology, the fluoride containing alloy was evaluated in the laboratory for fluoride release, enamel uptake and solubility, strength, hardness, flow, dimensional change, corrosion resistance, and marginal leakage. Clinically, 98 pairs of test and control restorations were placed and evaluated for marginal adaptation, surface characteristics, and recurrent caries. The results indicate that the fluoride containing alloy meets the ADA specifications for amalgam alloys, though the strength properties of the amalgam are reduced. The increased susceptibility to corrosion noted in the laboratory for the fluoride-containing amalgam did not correlate with the clinical performance of the restorations, which showed no deleterious affects resulting from the addition of the fluoride compound. The reduced enamel solubility observed in the laboratory can be considered an adjunct in the prevention of recurrent caries, though no recurrent caries was reported for either the test or control restorations. Again, the prevention of recurrent caries must begin with appropriate cavity design, care in manipulation of materials and responsible diet and hygiene practices.

A composite resin versus an amalgam: a study of certain properties and the design and initiation of a clinical investigation

Avery, David Roger January 1971 (has links)
Indiana University-Purdue University Indianapolis (IUPUI) / Certain properties of a representative composite material were evaluated by in vitro testing and compared to those of other types of restorative materials. A clinical study designed to evaluate the performance of the composite material as compared to amalgam for Class II restorations was initiated and one-year results are reported. Laboratory tests for abrasion resistance, hardness, marginal leakage, strength, color stability, staining characteristics, solubility, and water sorption were conducted. The clinical study is still in progress but the results after one year indicated that the composite resin test restorations, as well as the amalgam control restorations, were generally satisfactory. In overall clinical performance neither material was superior to the other. The amalgam restorations received a superior rating for anatomic form while the composite restorations were superior in terms of marginal adaptation. No clinical evidence of recurrent caries, associated with any of the restorations, was detected. Surface discoloration was a significant finding on the composite restorations, but it was confined to proximal areas and may be related to the difficulty of cleaning these areas with a toothbrush. No conclusions can yet be made regarding the long-term clinical performance of the composite resin used in this investigation as a Class II restorative material.
