Propylthiouracil is used in the treatment of what?

  1. Periodontitis

  2. Enamel mottling

  3. Hyperthyroidism

  4. Hypothyroidism

The correct answer is: Hyperthyroidism

Propylthiouracil is a medication that is used to treat hyperthyroidism, a condition where the thyroid gland is overactive and producing too much thyroid hormone. This medication works by blocking the production of thyroid hormones, helping to restore balance in the body. Option A, periodontitis, is incorrect because it refers to a bacterial infection of the gums, which has nothing to do with the function of the thyroid gland. Option B, enamel mottling, is also incorrect because it refers to a condition where the enamel on teeth becomes discolored, and is not related to the use of propylthiouracil. Option D, hypothyroidism, is the opposite of hyperthyroidism and is a condition where the thyroid gland is underactive, so propylthiouracil would not be an effective treatment. In
