Which one of the following instruments is specifically used to remove calculus from the interproximal areas of teeth?

The instrument specifically designed to remove calculus from the interproximal areas of teeth is the push scaler. This tool allows dental professionals to effectively address the challenging areas between teeth where plaque and calculus can accumulate and be difficult to reach with other types of scalers. The push scaler typically has a thin, narrow blade that enables it to maneuver easily into these tight spaces, facilitating the removal of deposits without damaging the adjacent tooth surfaces.

Other scalers may have their own specialized functions, but the unique design of the push scaler makes it ideal for interproximal cleaning, ensuring thorough oral hygiene and helping prevent gum disease. This particular focus on the interproximal areas emphasizes the push scalers' effectiveness as an essential instrument in dental practice.
