In which aspect is the maxillary lateral incisor NOT smaller than the maxillary central incisor ______________?
Show answer Hide answer
Answer: D. Root length
Explanation
The root length of the maxillary lateral incisor is typically greater or equal. Therefore it is not smaller in this specific anatomical dimension. Its root often features a distinct distal curve near the apex. Maxillary lateral incisors are generally smaller than central incisors in most aspects. Crown width and length are both noticeably reduced on the lateral incisor. Root proportion comparisons help identify extracted anterior teeth accurately.
Endodontic access must account for the curved root apex of lateral incisors. Aesthetic restorations compensate for smaller crown widths by reshaping proportions. Anatomical variations like peg lateral incisors deviate significantly from these norms. Crown length is indeed smaller on the maxillary lateral than the central incisor. Mesiodistal crown width is markedly smaller on the lateral incisor. Faciolingual crown width is also smaller on the lateral incisor compared to the central.
