1. Periodontitis

2. Periodontal pocket

3. Cavity

4. Gingivitis

The correct answer is: Periodontal pocket

The condition that is characterized by deepening of the gingival sulcus is indeed the periodontal pocket. This occurs when there is a loss of connective tissue and alveolar bone around the teeth, which leads to the formation of a pocket between the gum tissue and the tooth. When the gingival sulcus, which is the space between the tooth and the healthy gum, becomes deeper than normal (greater than 3 mm), it indicates periodontal disease. In periodontal pockets, favorable conditions for bacteria to thrive can develop, leading to further periodontal issues. Recognizing this deepening is important for diagnosing periodontal disease, as it signifies a more advanced stage beyond just inflammation or bleeding gums, such as what is seen in gingivitis. Other conditions like periodontitis involve the inflammation of the supporting structures of the teeth which can also be linked to the presence of periodontal pockets, but the term specifically "periodontal pocket" refers directly to the condition of a deepened sulcus. Understanding these distinctions is crucial for effective dental diagnosis and treatment planning.
