What does hypodontia refer to in dental terminology?

1. Presence of extra teeth

2. Missing teeth due to lack of growth

3. Teeth with excessive wear

4. Teeth that are discolored

The correct answer is: Missing teeth due to lack of growth

Hypodontia refers to the condition characterized by the absence of one or more teeth due to a lack of development. This condition typically arises during the developmental stages of the child’s dentition, often affecting permanent teeth. While a person with hypodontia may have some teeth present, the condition specifically indicates that there are fewer teeth than expected in the dental arch. Understanding this term is crucial in dentistry as it can significantly impact a person’s oral health, chewing function, and aesthetic appearance. Treatment for hypodontia often involves planning for prosthetic replacements or orthodontic interventions, depending on the specific teeth that are missing and the overall dental health of the patient. The other options represent different dental conditions: the presence of extra teeth relates to hyperdontia, excessive wear is associated with attrition or abrasion, and discolored teeth are indicative of conditions like staining or dental fluorosis.
