in primary first molar which portion of the crown is shorter occlussogingival

a.mesial
b.distal
c.midfacial
d.midlingual

 

[wise146]

I think distal but I am not sure, anybody have an explanation

 

[wireless_doc]

My guess would be mesial because of the curve of Spee.

 

[confused tooth]

If you consider the cervical line relation, cervical line on mesil is higher than distal, whic makes distal portion shorter occluso-gingivally.....correct me if I am wrong

Distal makes sense. AFAIK all teeth are shorter occlusogingivally on the distal than the mesial (aside from MD centrals). It's one of those general trends that helps cut down on memorization.

the in primary first molar of the mandible the mesial trasnv.rige separete the rest of the occlusal surfase(the mesial trasnv.rige is higher than the small distal trasnv. rige).The shortes occlusal area of the in primary first molar of the maxilla in the distolingual. So with all this information, hands down the answers for your question is Distal .

To me it's actually the simple question of what cusp is shorter in primary molars.
However it doesn't specify which arch we are talking about so I tried to discuss them both. It's B and
