Question

List in sequential order the largest to smallest cusp: primary

a.MAX + MAN - M1,
b.M2 perm
c.MAX + MAN - M1,
d.M2

Answer 1

Listing from largest to smallest for the given cuspids in human dentition would be the permanent first molars, followed by the permanent maxillary second molar, and finally the primary first molars with the primary second molar being the smallest.

Step-by-step explanation:

The student's question pertains to the comparative size of cuspids in human dentition, specifically the primary and permanent maxillary (MAX) and mandibular (MAN) first molars (M1) and the permanent maxillary second molar (M2). Given the developmental biology of dentition, the largest to smallest would generally be as follows:

1. Primary MAX + MAN - M1: Typically, primary molars are smaller than permanent molars.
2. MAX + MAN - M1: The permanent first molars are larger than primary molars and have a broader chewing surface.
3. M2 perm: The permanent maxillary second molar is usually slightly smaller than the first molar but larger than primary molars.
4. d.M2: If this refers to a deciduous (primary) molar, it would likely be the smallest; if permanent, it would follow the trend above.
