title: The antibacterial properties of four elements released from dental restorative materials.
abstract: The antibacterial activity of four elements (zinc, copper, fluoride and mercury), previously reported to be released from dental restorative materials, was investigated. This was carried out using two aerobic micro-organisms isolated from dentine beneath cavities in the ferret. These were grown in the presence of the test elements over a concentration range of 10-100 micrograms/ml for 72 hours. Concentration and exposure time were found to have a highly significant effect on the growth and viability of both micro-organism. Zinc, mercury and copper exerted the greatest effect, fluoride the least.
