Which instrument is commonly used for scaling teeth?

The correct choice for the primary instrument used for scaling teeth in a dental hygiene context is the hand scaler. Hand scalers are specifically designed for the manual removal of plaque, calculus, and other debris from the surfaces of teeth, particularly in tight spaces such as interproximal areas. They come in various shapes and sizes, allowing dental hygienists to effectively remove deposits above and below the gum line.

While ultrasonic scalers may be effective and are often utilized in dental practices for scaling purposes due to their ability to vibrate at high frequencies and remove calculus more efficiently than hand instruments, the hand scaler remains fundamental for detailed, precision work during dental cleanings.

In contrast, the dental mirror is primarily an instrument for visualization, allowing practitioners to see areas of the mouth that are otherwise difficult to observe. The probe is often used for probing gum pockets to assess periodontal health, rather than for scaling. Thus, while all these instruments play vital roles in oral hygiene and dental care, the hand scaler is the most commonly used instrument specifically for scaling teeth during routine cleanings.
