HOSA Dental Terminology Practice

What term is used for having fewer teeth than normal due to congenital issues?

1. Hypodontia

2. Macrodontia

3. Amelogenesis imperfecta

4. Anodontia

The correct answer is: Hypodontia

Hypodontia is the term that refers to having fewer teeth than normal due to congenital issues. This condition typically means that one or more teeth have not developed, resulting in a reduced number of teeth in an individual's dentition. It can affect both primary (baby) teeth and permanent teeth, manifesting in a variety of patterns. In comparison to other terms, macrodontia refers to teeth that are larger than normal, which is unrelated to the quantity of teeth present. Amelogenesis imperfecta describes a condition affecting the enamel of the teeth, leading to problems with how the enamel forms; it does not factor in the number of teeth. Anodontia, on the other hand, signifies the complete absence of teeth, which is a more severe condition than hypodontia where some teeth are still present. Understanding these distinctions helps clarify dental terminology and conditions associated with tooth development.
