1. It is associated with platelet-specific autoantibodies: This statement is true. ITP is characterized by the presence of autoantibodies that specifically target and destroy platelets, leading to thrombocytopenia (low platelet count).

2. It causes a prolonged bleeding time: This statement is true. In ITP, the low platelet count results in a prolonged bleeding time, as there are fewer platelets available to form a clot.

3. It is often controllable by immunosuppressive treatment: This statement is true. ITP can often be managed with immunosuppressive therapies, such as corticosteroids, intravenous immunoglobulin (IVIG), or other immunosuppressive agents, to help increase platelet counts.

4. It causes more prolonged hemorrhage than hemophilia: This statement is not true. While both ITP and hemophilia can lead to bleeding, the mechanisms are different. Hemophilia is a clotting factor deficiency, which can lead to more severe and prolonged bleeding episodes, especially after trauma or surgery. In contrast, ITP primarily affects the number of platelets rather than the clotting factors. Therefore, the bleeding in hemophilia can be more severe and prolonged compared to that in ITP.

A positive tuberculin skin test indicates a past exposure to TB bacteria, which has led to the development of an immune response. Latent TB infection is asymptomatic and does not imply active disease. Further tests are needed to rule out active TB.

While systemic conditions like diabetes, pregnancy, and steroid therapy can significantly alter tissue responses to irritants, cardiovascular disease is less likely to have a direct impact on local periodontal tissue responses.

Chlorhexidine gluconate is a broad-spectrum antimicrobial agent. A well-known side effect of its use is the reversible brown staining of teeth, the tongue, and silicate or composite restorations.
