In subgingival scaling, which instrument is primarily avoided for calculus removal?

In the context of subgingival scaling, the sickle scaler is primarily avoided for calculus removal because it is specifically designed for supragingival use. Sickle scalers have sharp, curved blades that excel at removing calculus from above the gum line but can be damaging to the tissues in the periodontal pocket.

When performing subgingival scaling, the primary goal is to clean the root surfaces below the gum line gently and effectively, which typically requires instruments that are designed for this purpose, such as universal and Gracey curettes, as they have rounded tips that can navigate and adapt to the root surface without risking trauma to surrounding soft tissues. Hand scalers can also be used in specific situations, but care must be taken to avoid creating unnecessary trauma.

Using inappropriate instruments, like a sickle scaler, in the subgingival area can lead to patient discomfort and tissue damage, potentially worsening periodontal conditions rather than helping. Therefore, it is crucial to select instruments specifically designed for subgingival work when addressing calculus removal in these areas.
