**Core Concept**
Delayed dentition, also known as hypodontia, is a condition characterized by the partial or complete absence of teeth. This condition can be due to various factors, including genetic, environmental, and developmental causes.

**Why the Correct Answer is Right**
Delayed dentition is often associated with conditions such as hypothyroidism, Turner syndrome, and Down syndrome. In these conditions, the normal development of teeth is disrupted, leading to delayed or absent eruption of teeth. The underlying pathophysiology involves the disruption of the normal dental development process, which is regulated by a complex interplay of genetic and hormonal factors.
