Another term for overgrown gingival tissue is?

Atrophy
Hyperplasia
Hypotrophy
Caries

The correct answer is: Hyperplasia

Overgrown gingival tissue is a result of an increase in the number of cells, known as hyperplasia. Atrophy refers to a decrease in the size or function of tissue, so it is the opposite of overgrown tissue. Hypotrophy is also a decrease in tissue, but specifically refers to a decrease in the size of individual cells. Caries is a term used to describe tooth decay, which is unrelated to overgrown gingival tissue. Therefore, the term for overgrown gingival tissue is hyperplasia.
