Which incisor is most likely to have 2 roots and 2 canals?

  1. Mandibular lateral

  2. Mandibular central

  3. Maxillary central

  4. Maxillary lateral

The correct answer is: Mandibular lateral

The mandibular lateral incisor is most likely to have 2 roots and 2 canals. This is because it is the largest and strongest incisor in the lower jaw and requires extra support from the additional root. Additionally, the mandibular central incisor only has one root, while the maxillary central and lateral incisors typically have one root and one canal. This can vary from person to person, but the mandibular lateral incisor is the most common tooth to have 2 roots and 2 canals.
