What is likely to result from effective nonsurgical treatment in terms of quality of life?

Effective nonsurgical treatment in periodontal therapy primarily focuses on improving oral health, which can significantly enhance a patient's quality of life. Greater psychological comfort arises from the reduction in oral pain and discomfort, improved aesthetics, and the increased ability to engage in social interactions without the anxiety associated with periodontal disease. As individuals experience improved oral health, they tend to feel more confident in their appearance, experience less anxiety about dental visits, and generally have a more positive outlook on their overall health and well-being.

The other options — increased dietary restrictions, worsened mobility, and improved economic conditions — do not directly relate to the benefits of nonsurgical periodontal treatment. While effective treatment may allow for a broader range of dietary choices due to improved oral condition, it is not associated with increased restrictions. Similarly, mobility is not a direct outcome of periodontal treatment, and while improved quality of life may have some economic benefits, the immediate psychological comfort resulting from improved oral health is clearer and more direct.
