Which of the following would be an appropriate adjunctive therapy for periodontal disease?

Adjunctive therapy for periodontal disease aims to support the primary treatment of established periodontal conditions, such as scaling and root planing, to enhance healing and improve patient outcomes. Antibiotics are an appropriate adjunctive therapy as they can help control bacterial infections associated with periodontal disease. They are effective in reducing the microbial load, thereby assisting in the management of inflammation and promoting periodontal tissue healing.

The use of antibiotics may be particularly beneficial in cases of aggressive periodontitis or when there is a need to manage localized pockets with significant bacterial presence. The incorporation of antibiotics into treatment protocols allows for a more comprehensive approach to managing the pathology associated with periodontal conditions.

Other options, such as vitamins, do not have a specific evidence-based role in the active treatment of periodontal disease, even though some vitamins may support overall health. Cosmetic dental procedures and home whitening kits do not address the underlying pathophysiology of periodontal disease and are primarily focused on aesthetics rather than therapeutic intervention. Thus, they do not contribute to the management or resolution of the disease process.
