distal

3

True or False. The distobuccal groove is unique to the second molar, starts at the central groove and extends between the distobuccal and distal cusps.

false (first molar)

4

on a mandibular second molar, where is the mesial contact point?

junction of middle and buccal third

5

on some ___ molars, there may be a small 5th cusp called the cusp of carabelli on the ___ lingual surface.

first, lingual

6

this tooth can have a 5th cusp, Cusp of Carabelli, located on the lingual surface of the ___ cusp

maxillary 1st molar, mesiolingual

7

what is the mesial contact pint of the maxillary 1st molar?

junction of occlusal and middle thirds

8

the mesiolingual cusp of the tooth is larger than the distolingual cusp.

maxillary 1st molar

9

on the mesial, the roots of this tooth usually extend wider than the crown.
