In which tooth is mesiodistal width greater than its height in both dentitions?

Maxillary central incisor
Mandibular central incisor
Maxillary lateral incisor
Mandibular lateral incisor

The correct answer is: Maxillary central incisor

In both primary and permanent dentitions, the mesiodistal width is greater than its height in the maxillary central incisors. This is due to the fact that the maxillary central incisors have a triangular shape with the apex at the incisal edge, making them wider at the base. The mandibular central incisors have a rectangular shape, making them more square and having equal mesiodistal width and height. The maxillary lateral incisors have a rectangular shape, similar to the mandibular central incisors. The mandibular lateral incisors have a tapered shape, but they are still more square compared to the maxillary central incisors. Therefore, the correct answer is A, as the maxillary central incisors are the only teeth in which the mesiodistal width is greater than its height in both dentitions.
