Which instrument is included in the setup for periodontal surgery?

In periodontal surgery, the inclusion of a curette in the surgical setup is essential because this instrument is specifically designed for removing soft tissue and subgingival plaque and calculus from the periodontal pocket. Curettes have a rounded end that allows for careful debridement, minimizing trauma to the surrounding tissues while ensuring effective cleaning of the area.

The curette's design, which features a spoon-shaped blade, makes it ideal for scaling and root planing procedures, which are critical components in treating periodontal diseases. The use of this instrument helps in achieving a clean root surface and promoting healing in the periodontal tissues.

In contrast, while suction, scalpel, and forceps play important roles in various surgical procedures, they serve different functions. Suction is primarily used for managing fluids and debris during surgery rather than for direct treatment of periodontal issues. A scalpel is often used to make incisions but is not specifically designed for the cleaning of periodontal pockets, and forceps may be used for handling tissues but are not central to the debridement process. Hence, the curette's unique purpose and functionality make it a vital instrument in the context of periodontal surgery.
