Which action is not included in the UK plan to regulate dental amalgam?

The plan to regulate dental amalgam in the UK focuses on minimizing its environmental impact and ensuring safe practices in dental treatment. The introduction of amalgam separators on all dental units is aimed at preventing mercury from entering the wastewater system, which aligns with environmental guidelines. Limiting the use of amalgam to pre-dosed capsules ensures that the material is used in a controlled manner, reducing waste and the risk of spillage. The regulation also targets vulnerable populations by restricting the use of amalgam in children under the age of 15, as they may be more susceptible to potential health risks associated with mercury exposure.

However, the non-use of amalgam in patients with dementia is not a specific regulation outlined in the UK's guidelines. While individuals with certain health conditions may warrant careful consideration regarding their dental treatment, dementia alone does not automatically exclude a patient from receiving dental amalgam when clinically appropriate. Thus, the action mentioned in this choice does not represent part of the established regulatory guidelines.
