Microdontia typically affects how many teeth?

• A. One or two teeth
• B. All teeth
• C. Three to five teeth
• D. Six or more teeth

Answer: (A)

Microdontia is a dental condition characterized by teeth that are smaller than the normal size. This condition can affect either one specific tooth (often a single smaller tooth like a maxillary lateral incisor) or a small number of teeth. The most common presentation of microdontia is localized, which means it typically involves one or two teeth rather than multiple teeth throughout the mouth.

When considering the options, the prevalence of microdontia in an isolated manner supports the understanding that it usually affects a limited number of teeth, thus making the choice of one or two teeth the most accurate. In contrast, the other options suggest a more widespread occurrence, which is less commonly seen in clinical practice. Therefore, the assertion that microdontia typically affects one or two teeth is substantiated by its common presentation in dental scenarios.
