Rank the size of cusps on maxillary first molar.

ML>MB>DL>DB>Cusp of Carabelli
MB>ML>DL>DB>Cusp of Carabelli
MB>ML>DB>DL>Cusp of Carabelli
ML>MB>DB>DL>Cusp of Carabelli

The correct answer is: ML>MB>DL>DB>Cusp of Carabelli

In the maxillary first molar, the size of cusps can be ranked as follows: - The MesioLingual (ML) cusp is usually the largest cusp on the maxillary first molar. - The MesioBuccal (MB) cusp is typically the next largest after the ML cusp. - The Distolingual (DL) cusp is smaller than both the ML and MB cusps. - The Distobuccal (DB) cusp is usually smaller than the DL cusp. - The Cusp of Carabelli is a small, tubercle-like structure found on the mesial lingual aspect of the maxillary first molars in some individuals. Therefore, the correct ranking for the size of cusps on the maxillary first molar is as follows: ML>MB>DL>DB>Cusp of Carabelli, which aligns with option A.
