mand 2nd pm doesn't have a mesial root depression/or is least likely to have compared to the other premolars.
max 1st pm ,max 2nd pm & md 1st pm have mesial root depressions with the max 1st pm being the most prominent.
p.s: check out wheelers if u have it🙂

yes, answ: max 2nd pm.
"on single -root specimens, the concavity on the crown and root is also plainly seen, althouth it may not be as deeply marked. Masilarry second premolars don not have this feature." Wheeler's chapter 9, pg149.

 

[dentimax]

bifurcation is correct.

yeah..i read it too but on pg194(chapter 9) in wheelers(6th edition) it says for max 2nd pm(under mesial aspect)
'A shallow developmental groove appears on the single tapered root'

I thought the best ans was mand 2nd pm among the given options since there is no description of any developmental depression/groove for it.
I'm now thoroughly confused 😕 can anyone plz confirm

i think ans is mand 2nd premolar.pls confirm....
