Environmental Impacts of Mercury-free Dental Materials
With the introduction of Article 10 of Regulation (EU) 2017/852, dental amalgam use has become restricted within the EU, which in turn has led to an increase in use of mercury-free dental alternatives.
During her research, Hannah aims to determine the particle size, shape, distribution and likely chemical composition of particles resulting from the use of these mercury-free dental materials using a range of analytical chemistry methods. Furthermore, she aims to quantify the waste streams resulting from the use of mercury-free materials leaving the dental surgery. A third objective of this study is to determine the efficacy and efficiency of amalgam separators (an amalgam filtering device either built directly into the dental chair or built into the dental clinic) to also remove particles resulting from mercury-free dental materials. And lastly, ecotoxicity testing will be carried out to determine potential hazards from particles of mercury-free dental materials.
This material is based upon research supported by the Irish Environmental Protection Agency under Grant Award No 2017-HW-MS-11.
