Practices of Dental Amalgam Disposal: A Scoping Review

Dental amalgam is considered a hazardous dental material, as it can affect both the environment and the health of professionals in the field. This study analyzed dental amalgam disposal practices over the past 10 years (2014–2024). The PRISMA 2020 method and the PubMed database were used, resulting in a final sample of 10 articles suitable for analysis. The knowledge gaps on the subject were organized into three axes: waste disposal and occupational exposure, dental waste management and regional challenges, and the future of sustainable dentistry. Among the factors influencing the choice of material are its durability, low cost, and professional experience. A relevant point identified was the lack of knowledge among professionals regarding the toxicity of amalgam, especially concerning proper disposal and exposure, which are often not carried out adequately.
