What is the term for the condition of having fewer than the normal number of teeth?

1. Anodontia

2. Fusion of teeth

3. Hypodontia

4. Hyperdontia

The correct answer is: Hypodontia

The term that refers to the condition of having fewer than the normal number of teeth is hypodontia. This condition occurs when some teeth are missing, which can result from various factors, such as genetic predispositions, developmental issues, or environmental influences. Hypodontia typically affects the permanent dentition and can lead to spacing issues, bite problems, and challenges with aesthetics. Understanding this term is crucial in dentistry as it helps dental professionals diagnose and manage related complications that may arise from the absence of teeth. Anodontia, which is also mentioned, describes a more severe condition where there are no teeth present at all. The confusion between these terms is common, as both involve the absence of teeth, but hypodontia specifically addresses having fewer teeth, whereas anodontia indicates the complete absence. Fusion of teeth refers to two teeth being joined together, and hyperdontia is the condition of having extra teeth, which are distinctly different from having a reduced number of teeth. Understanding these distinctions can aid in better diagnosing and treating various dental conditions.
