The deciduous tooth which does not have a resemblance to any other teeth is: PGCEE MDS 2022

 # The deciduous tooth which does not have a resemblance to any other teeth is:
a) Maxillary first molar 
b) Mandibular first molar
c) Maxillary 2nd molar 
d) Mandibular canine



The correct answer is B. Mandibular first molar.

The deciduous mandibular first molar is unique in that it has a crown form unlike that of any permanent tooth. It does, however, have two strong roots, one mesial and one distal—an arrangement similar to that of a mandibular permanent molar. These two primary teeth, the maxillary and mandibular first molars, differ from any teeth in the permanent set when crown forms are compared, in particular.
