MICROANATOMY

Detailed explanation-1: -The Cusp of Carabelli is a characteristic morphological trait often seen on the palatal surface of the mesiopalatal cusp of maxillary permanent molars and maxillary second deciduous molars [2].

Detailed explanation-2: -Of all the maxillary molars, the first molar is the least variable in anatomic form, and is thus the standard to which the other maxillary molars are compared. There are four major cusps and one minor, sometimes indistinct cusp, which is the cusp of Carabelli.

Detailed explanation-3: -The cusp of Carabelli, or Carabelli’s tubercle, or tuberculum anomale of Georg Carabelli is a small additional cusp at the mesiopalatal line angle of maxillary first molars.

Detailed explanation-4: -On many maxillary first molars, there is a fifth, much smaller cusp (cusp of Carabelli) located on the lingual surface of the longest and largest mesiolingual cusp (Appendix 8i). The number of lobes forming molars is one per cusp, including the cusp of Carabelli.
