Which tooth may develop the cusp of Carabelli?

Explanation:
The cusp of Carabelli is an extra cusp that appears on the lingual (tongue-side) surface of the maxillary first permanent molar, specifically near the mesiolingual area. Because this extra cusp occurs on the upper first molar rather than on the lower teeth or on canines or incisors, the upper first molar is the tooth that may develop it. It’s a genetic variation seen in some individuals and varies in frequency among populations.
