Admission Test for Dental Hygiene (ATDH) Practice

Which tool is commonly used in dental hygiene for scaling?

1. Dental mirror

2. Dental scaler

3. Ultrasonic cleaner

4. Toothbrush

The correct answer is: Dental scaler

The dental scaler is a specialized instrument that is specifically designed for scaling, which involves the removal of plaque, tartar, and calculus from the surfaces of the teeth, especially below the gumline. This tool is essential for maintaining oral health as it helps prevent periodontal disease and cavities. Dental scalers come in various shapes and sizes, allowing dental hygienists to access different areas of the mouth effectively. They can be hand-held instruments or powered devices, which provide efficient removal of hard deposits on teeth. Understanding the proper use of a dental scaler, including the angling and pressure required for effective treatment, is crucial for any dental hygiene practice. In contrast, other tools such as dental mirrors, ultrasonic cleaners, and toothbrushes do play integral roles in dental hygiene but do not serve the primary function of scaling teeth. A dental mirror, for instance, is used mainly for visibility and accessibility during procedures, while ultrasonic cleaners are utilized to clean instruments rather than for direct patient care. A toothbrush helps with daily dental care but does not achieve the same level of cleanliness as a scaler during professional dental cleanings.
