HOSA Dental Terminology Practice

Which of the following tools is mainly used to remove calculus or flash?

1. Glass dappen dish

2. Metal matrix band

3. Periodontal scaler

4. Endo broche

The correct answer is: Periodontal scaler

The periodontal scaler is specifically designed for the removal of calculus and plaque from the surfaces of teeth, particularly in the context of periodontal therapy. Calculus, also known as tartar, is hardened plaque that adheres to the teeth and can only be effectively removed with specialized instruments. The scaler has sharp, pointed edges that allow dental professionals to manually scrape away these hardened deposits from both supragingival (above the gumline) and subgingival (below the gumline) areas. Instruments like the glass dappen dish, metal matrix band, and endo broche serve distinct purposes in dentistry. The glass dappen dish is used for mixing dental materials, the metal matrix band is primarily used in restorative procedures to create a temporary wall for filling cavities, and the endo broche is designed for endodontic treatments, such as cleaning and shaping the inside of root canals. None of these tools are meant for the direct removal of calculus, making the periodontal scaler the appropriate choice for this task.
