Which of the following is NOT a purpose of periodontal dressing?

The correct choice highlights that attracting plaque is not a purpose of periodontal dressing. In fact, periodontal dressings are designed to assist in healing and protecting the surgical site after periodontal procedures. Their main functions include stabilizing gum tissue, controlling bleeding, and preventing infection.

Periodontal dressings act as a protective barrier, which helps to maintain the gum tissue's integrity and promote recovery. They can also help to manage immediate postoperative bleeding by providing compression and stability to the area. Additionally, these dressings usually have antimicrobial properties, which aid in reducing the risk of infection during the critical healing period.

The role of attracting plaque is not compatible with the objectives of periodontal dressings. Instead, a buildup of plaque can lead to complications such as increased inflammation and infection, which is exactly what these dressings are intended to prevent. Consequently, the assertion that attracting plaque is a purpose of periodontal dressing is fundamentally inaccurate.
