Which maxillary anterior teeth are known to have 2 roots?

Tooth #5, which is the maxillary lateral incisor, and tooth #12, which is the maxillary first molar, are the correct choices when identifying maxillary anterior teeth that may have two roots. Maxillary first molars are well-known for having three roots, but they can also exhibit unique anatomical variations, where the mesiobuccal root may occasionally present as two distinct roots. In contrast, maxillary lateral incisors typically have a single root; therefore, they do not contribute to options regarding two-rooted maxillary anterior teeth.

Anatomically, maxillary incisors such as teeth #7 (central incisors) and #8 (also central incisors) are characterized by a single root, reinforcing that maxillary anterior teeth traditionally do not have multiple roots. Nevertheless, it is essential to understand that the complexity of dental anatomy can lead practitioners to encounter variations that challenge common knowledge. The correct identification here emphasizes the importance of recognizing variations in dentition while understanding that typical dental anatomy usually features single roots in maxillary anterior teeth.
