To reduce mercury contamination in the dental office, which action should be avoided?

Installing carpet in the operatories is the action that should be avoided to reduce mercury contamination in the dental office. Carpeting can accumulate dust and particulates that may contain mercury and other contaminants, making it difficult to maintain a clean and safe environment. Unlike hard flooring, carpets can trap these materials and increase the risk of exposing dental staff and patients to hazardous substances.

In contrast, other actions like the replacement of old or damaged amalgam capsules and avoiding heating mercury or amalgam contribute positively to safety by preventing potential mercury leaks or releases during procedures. Eliminating heating sources like baseboard heaters can also help minimize the risk of mercury vaporization. These measures are more effective in maintaining a safe dental environment and reducing the risk of mercury exposure.
