Which instrument features a rounded tip?

The instrument that features a rounded tip is the curette. Curettes are dental instruments specifically designed for the purpose of scaling and root planing. Their rounded tips enable them to effectively remove deposits and debris from root surfaces and periodontal pockets gently and thoroughly. This rounded design minimizes the risk of damaging the tooth structure or surrounding tissues during procedures in the periodontal environment where precision is critical.

In contrast, other instruments like scalers have sharper tips designed for the removal of calculus from tooth surfaces, while chisels have a flat cutting edge meant for cutting or shaping dental hard tissue. Files are typically used to smooth or finish a surface and have a more rigid, pointed design that is not suited for the gentle manipulation required in periodontal treatment. Therefore, the rounded tip of the curette is essential for providing safe and effective care in periodontal practices.
