Correct answer: A — Mesiodens
A mesiodens is a supernumerary tooth situated in the maxillary midline between the central incisors. It may be erupted or unerupted and can interfere with the eruption or alignment of the permanent incisors. A paramolar lies adjacent to a molar, whereas a distomolar is situated distal to the normal molar series, typically behind a third molar. Parapremolar and paracanine describe supernumerary teeth located in the premolar and canine regions, respectively. The midline anterior maxillary location therefore uniquely identifies a mesiodens.
