Hypodontia, which refers to the developmental absence of one or more teeth, is particularly associated with Down's syndrome. Individuals with Down's syndrome often exhibit a range of dental anomalies, including hypodontia, which can affect both primary and permanent teeth. This condition is linked to the chromosomal abnormalities characteristic of Down's syndrome, which not only impact overall health but also influence various aspects of dental development.

While the other conditions listed may involve dental issues, they are not primarily associated with hypodontia. Cleidocranial dysplasia is more often linked with the presence of supernumerary teeth or other dental anomalies rather than their absence. Papillon-Lefevre syndrome typically presents with severe periodontitis leading to tooth loss, while rickets involves issues related to bone mineralization and does not directly correlate with hypodontia. Understanding these associations helps in recognizing the spectrum of dental anomalies that may occur in patients with specific genetic or systemic conditions.
