 # From which view are only two roots visible on a maxillary first molar?
a. Mesial
b. Distal
c. Buccal
d. Lingual


The correct answer is A. Mesial.

On both the maxillary first and second molars from the mesial view, two roots can be seen: the lingual
root and the mesiobuccal root, which is considerably wider buccolingually than the hidden distobuccal root.  On the first maxillary molar, the convex buccal outline of the mesiobuccal root often extends a little buccal to the crown outline, but the apex of this root is in line with the tip of the mesiobuccal cusp.
