Which premolar is most likely to have 1 root and 1 canal?

  1. Maxillary 1st premolar

  2. Mandibular 1st premolar

  3. Maxillary 2nd premolar

  4. Mandibular 2nd premolar

The correct answer is: Mandibular 2nd premolar

The mandibular 2nd premolar is most likely to have 1 root and 1 canal. Mandibular premolars typically have two roots: one mesial and one distal. However, the mandibular 2nd premolar often has one root and one canal, unlike the mandibular 1st premolar which usually has two roots and the maxillary premolars which typically have multiple roots and canals.
