Which condition is characterized by the presence of deep periodontal pockets?

Periodontitis is characterized by the presence of deep periodontal pockets. This condition involves inflammation of the supporting structures of the teeth, including the gums, periodontal ligaments, and alveolar bone. As periodontitis progresses, it leads to the destruction of these supportive tissues, resulting in the formation of deep pockets between the gums and teeth. These pockets become spaces where bacteria can accumulate, further exacerbating the condition and potentially leading to tooth mobility or loss if not treated.

In contrast, gingivitis, which is often an early stage of periodontal disease, primarily involves inflammation of the gums without the loss of supporting structures, typically resulting in shallower pockets. Tooth decay, unrelated to periodontal health, refers to carious lesions in the tooth structure itself. Oral candidiasis is a fungal infection that affects the mucosal surfaces of the mouth and does not involve the periodontal tissues or the formation of deep pockets. Therefore, the defining characteristic of deep periodontal pockets is specifically a hallmark of periodontitis.
