Which of the following are examples of amalgam carvers?

Amalgam carvers are specialized dental instruments designed for shaping and carving dental amalgam after it has been placed in a cavity preparation. The primary purpose of these carvers is to achieve a smooth surface and proper anatomical contours that mimic the natural structure of the tooth.

The correct choice highlights two common types of amalgam carvers: Hollenback and discoid-cleoid carvers. The Hollenback carver is particularly effective for refining the margins of dental restorations and ensuring the amalgam fits snugly within the cavity walls, while the discoid-cleoid carver excels at sculpting the occlusal surface, being especially useful in creating the grooves and cusps that restore normal tooth function and appearance.

Other options provided do not categorize instruments used specifically for carving amalgam. Scalers and curettes are typically used for periodontal procedures, focusing on the removal of plaque and calculus from tooth surfaces. Echo sounders and scalpers are not standard terms in dental instrumentation and do not refer to tools used in restorative dentistry. Chisels and gouges serve different purposes in dentistry, primarily for cutting or shaping enamel and dentin rather than specifically for carving amalgam.

Thus, recognizing the function of amalgam carvers is essential in restorative dentistry,
