In the early stage of gingivitis, gingival hemorrhage is commonly observed as a key clinical sign. This condition occurs primarily due to inflammation of the gingival tissues caused by the accumulation of plaque. As plaque buildup irritates the gums, small blood vessels become more permeable and prone to bleeding, especially during brushing or flossing.

In contrast, severe tissue loss, mobility of teeth, and formation of periodontal pockets are associated with more advanced stages of periodontal disease. Severe tissue loss indicates a chronic condition where the supporting structures of the teeth are compromised. Mobility of teeth often occurs when there is significant periodontal disease that has led to loss of attachment and bone. Formation of periodontal pockets is a sign of deeper tissue involvement and typically develops as gingivitis progresses into periodontitis. Thus, gingival hemorrhage serves as a hallmark of the early inflammatory response in gingivitis, making it the correct observation for this stage.
