Which instrument is characterized by having a pointed tip?

The instrument characterized by having a pointed tip is the scaler. Scalers are designed with sharp edges and pointed tips to effectively remove calculus and plaque deposits from the tooth surfaces, especially in interproximal areas and on enamel. Their shape and pointed nature are essential for their function, allowing for precise and effective scaling — particularly in subgingival areas where precise removal of deposits is critical for periodontal health.

Curettes, on the other hand, have rounded ends and are designed for smoother, more delicate removal of debris and deposits from the tooth surface without damaging the tissue. Explorers feature a pointed tip, but their primary purpose is to detect calculus, cavities, and defects in the tooth structure, rather than actively remove deposits. Periodontal probes, while also pointed, are used primarily for measuring pocket depths around a tooth, not for removal of calculus or for scaling. Therefore, the scaler stands out as the instrument specifically designed with a pointed tip for effective scaling.
