Which instrument is often used supragingivally for light calculus removal?

The hand scaler is specifically designed for the removal of light calculus and plaque from the tooth surfaces above the gum line, which is referred to as supragingival cleaning. Its sharp and pointed blade allows for effective scaling in areas where calculus tends to accumulate, such as along the margins of the gums and interproximal spaces.

Hand scalers are advantageous because their design enables the hygienist or dentist to have greater control and precision in delicate areas. This is particularly beneficial when dealing with sections that require a careful touch to prevent tissue damage.

In contrast, while Gracey curettes and universal curettes can also be used for calculus removal, they are typically better suited for subgingival cleaning, especially the Gracey curette, which is designed for specific tooth surfaces within the periodontal pocket. The periodontal probe is primarily used for measuring pocket depths and assessing periodontal health rather than for calculus removal. Thus, the hand scaler is the most appropriate choice for light supragingival calculus removal.
