Claims
- 1. A method of reducing secondary caries around an existing tooth restoration comprising the step of placing the fluoride releasing dental amalgam composition for a tooth restoration comprising a mixture of a dental amalgam alloy material and a glass particulate powder component of a fluoride-containing, fluoride-leachable acid-etchable glass ionomer cement, wherein the amalgam alloy material comprises:40-70% Silver 26-30% Tin 2-30% Copper 0-2% Zinc and the glass particulate powder comprises: 41.9-35.2% SiO2 28.6-20.1% Al2O3 1.6-2.4% AIF3 15.7-20.1% CaF2 9.3-3.6% NaF 3.8-12.0% AlPO4 in a prepared cavity area prone to tooth decalcification and/or overt decay.
- 2. A tooth bonded to the fluoride-releasing dental amalgam composition for a tooth restoration comprising a mixture of a dental amalgam alloy material and a glass particulate powder component of a fluoride-containing, fluoride-leachable acid-etchable glass ionomer cement, wherein the amalgam alloy material comprises:40-70% Silver 26-30% Tin 2-30% Copper 0-2% Zinc and the glass particulate powder comprises: 41.9-35.2% SiO2 28.6-20.1% Al2O3 1.6-2.4% AIF3 15.7-20.1% CaF2 9.3-3.6% NaF 3.8-12.0% AlPO4.
