Which preparation is used therapeutically as rinses to reduce plaque and gingivitis, and cosmetically to reduce bad breath?

• A. Mouthwash
• B. Gargle
• C. Syrup
• D. Suspension

Answer: (A)

Mouthwash is the preparation used as a therapeutic rinse to reduce dental plaque and gingivitis, and it can also help freshen breath for cosmetic purposes. As an oral rinse, mouthwashes deliver antimicrobial or antiseptic agents such as chlorhexidine, essential oils, or cetylpyridinium chloride that target the plaque biofilm on teeth and gingiva, helping to lessen inflammation and slow plaque buildup. Many formulations also provide a fresh breath effect, which is the cosmetic aspect.

Gargle refers to the action or method of rinsing the throat and mouth, rather than a specific therapeutic preparation. Syrups and suspensions are dosage forms used for ingestion or topical administration, not typically employed as rinses to control plaque or gingivitis.
