What is characterized by an increase in gingival tissue volume?

Gingival enlargement is characterized by an increase in gingival tissue volume, which can result from various factors such as inflammation, medication side effects, or systemic conditions. This increase in volume leads to swollen, overgrown gum tissues that can often cover the teeth and affect oral hygiene. It is crucial to understand that while pain and inflammation can accompany gingival enlargement, the essential feature that distinguishes this condition is the actual increase in tissue size.

Other conditions listed do not describe an increase in tissue volume. Painful gingivitis refers to inflammation of the gums that can cause discomfort but does not inherently involve an increase in size. A periodontal abscess is localized and involves pus, typically due to infection, leading to more destruction than swelling of the tissue. Gingival recession involves the loss of gum tissue, which results in the exposure of the tooth roots rather than an increase in volume. Recognizing these distinctions is vital for proper diagnosis and treatment planning in periodontal health.
