Maxillary Molar

[DrGeek]

One book says maxillary molars have 3 major cusps; another says maxillary 1st molar has 4 cusps (2 buccal & 2 lingual) plus a 5th minor cusp (cusp of Carabelli). How many major and minor cusps do they have?!!!!!!

I would reckon that the major would be both buccal cusps, and the mesiolingual. The minor would be the distolingual and the cusp of Carabelli.

Confusing, looks like there is no consensus
