Abstract
Physical properties of a high copper amalgam containing tannin-fluoride preparation and its alteration following immersion in water up to 12 months were examined in relation to its microstructure.
Any eminent effects were observed on the physical properties of resultant amalgam in regard to the admixed ratio of tannin-fluoride preparation up to 0.5%.However, apparent influences were observed at 1.0 wt%.
Effect of water immersion was apparent with the reduction of diametral tensile strength of amalgam containing 1.0 wt% tannin-fluoride. Remarkable change in compressive strength and static creep was not observed. Microstructural change was observed on amalgam containing tannin-fluoride regardless to its admixed ratio.
