What defines a periodontal pocket?

1. A healthy gum line

2. A pathologically deepened gingival sulcus

3. A type of dental filling

4. A tooth alignment issue

The correct answer is: A pathologically deepened gingival sulcus

A periodontal pocket is specifically defined as a pathologically deepened gingival sulcus. In healthy individuals, the depth of the gingival sulcus— the space between the tooth and the surrounding gum tissue—typically ranges from 1 to 3 millimeters. When there is gum disease, this depth can increase, forming what is known as a periodontal pocket, which is often a sign of periodontal disease. The presence of these deeper pockets indicates destruction of the supportive tissues and bone that hold the tooth in place, leading to further complications if not managed properly. This distinction is crucial for diagnosing periodontal health and implementing appropriate treatment strategies.
