Which instrument is typically used to place dental amalgam?

The amalgam plugger is the instrument specifically designed for placing dental amalgam. This tool is essential in the dental restorative process, as it allows for the precise placement and compaction of amalgam material into a tooth cavity. The design of the amalgam plugger includes a rounded or flat end that aids in pushing the amalgam into the cavity preparation, ensuring that it fills the space completely and securely. Proper compaction is critical as it helps to minimize the presence of voids in the filling, which can lead to failure or secondary caries.

Other instruments listed, such as the dental scaler, dental mirror, and explorer, serve different purposes in dental practice. A dental scaler is utilized for removing plaque and calculus from teeth surfaces, a dental mirror is used for visibility and indirect illumination during examinations, and an explorer is employed for probing cavities and detecting dental caries. Each of these tools has a unique function and is not suited for the specific task of placing or compacting dental amalgam. Hence, their roles in dental procedures do not overlap with that of the amalgam plugger.
