ABSTRACT
OBJECTIVES: This study assessed perceptions of health and science students and academic staff regarding the health risks, environmental impact, and regulation of dental amalgam (DA). As DA faces increasing restrictions, understanding the views of students and academic staff is essential for evaluating educational and policy readiness.
METHODS: A cross-sectional survey was distributed to 1,230 participants in the Czech Republic. The questionnaire explored awareness of mercury exposure from DA, health and environmental concerns, and familiarity with regulations. Responses were statistically compared across disciplines.
RESULTS: Overall, 35.8% of respondents did not recognize DA as a mercury source, and 48.5% did not view it as a health risk. Most did not consider DA an occupational hazard for dental professionals. However, 55.3% saw it as an environmental pollutant. While 59.2% supported restricting DA use in pregnant women and 51.0% in children, only 22.0% supported a complete ban. Most respondents preferred composites for aesthetic reasons (88.5%) rather than health concerns. Dental students differed significantly from other groups in several key areas, particularly regarding perceived health risks and support for restrictions on dental amalgam use.
CONCLUSIONS: Perceptions of dental amalgam differed according to educational background. While most participants supported restricting its use in vulnerable populations, dental students were less likely to perceive it as a significant health risk and were less supportive of a complete ban. These findings highlight the importance of evidence-based education and public health communication regarding dental amalgam and mercury-related issues.
