What is one main goal of nonsurgical periodontal therapy?

• A. To whiten teeth
• B. To eliminate plaque only
• C. To reduce bacterial load
• D. To straighten misaligned teeth

Answer: (C)

One main goal of nonsurgical periodontal therapy is to reduce bacterial load. This approach focuses on managing the microbial factors that contribute to periodontal disease, which is primarily caused by the accumulation of bacteria and plaque on the tooth surfaces and within the periodontal pockets. The therapy involves procedures such as scaling and root planing, which help to remove plaque, calculus, and toxins from the teeth and gums. By effectively reducing the bacterial load, the therapy aims to halt the progression of periodontal disease, reduce inflammation, and promote the healing of periodontal tissues.

The other options, while related to dental care, do not accurately reflect the primary objective of nonsurgical periodontal therapy. Whitening teeth is typically a cosmetic goal rather than a therapeutic one. Eliminating plaque alone does not encompass the broader aim of reducing inflammation and bacterial load for periodontal health. Similarly, straightening misaligned teeth pertains to orthodontics, which is not a focus or goal of periodontal therapy.
