why did u choose mesial
i would say distal as mesially the primary mand molars have well developped cusps .


and about transverse ridges in mand first molar: 2

Where are the 2 transverse ridges formed.? I know one connects the ML and MB ridges. How about the other.?

you are right its definitely not mesial and could be distal. not sure though?

 

[drkooks]

transversre ridge between one bu cusp and one li
so in man 1st molar
between MB and ML
DB and DL
