A

Distal lingually

30
Q

Where is the cingulum located on the mand lateral?

A

distal lingually

31
Q

Where is the cingulum located on the mand canine?

A

distal lingually

32
Q

A

Max Centrals

33
Q

Which is the only tooth with a cross section through the CEJ that appear triangular?

A

Max Central Incisor

34
Q

Most common congenitally missing or malformed teeth

A
  1. 3rds
  2. max laterals
  3. mand 2nd premolar
35
Q

T or F: The Max lateral root is shorter than the mand central root

A

False, it is long or longer and is distally inclined

36
Q

T or F: the max lateral incisor incisal edge slopes cervically from mesial to distal

A

True

37
Q

True or False: on the lateral max incisor, the distal marginal ridge is smaller than the mesial marginal ridge

A

Yes, due to the cervical slope of the incisal edge

38
Q

T or F from the incisal view, the max lateral incisor is more oval than the central

A

True

39
Q

Which tooth has a cingulum that is in the central and which is more distal? Max central or lateral

A

Max central cingulum is more distally displaced.
Max lateral cingulum is more central

40
Q

T or F The mand lateral has a distal lingual groove that makes scaling and root planing here more difficult

Smallest tooth in the mouth

A

Mand central incisor

42
Q

Narrowest tooth mesial distally

A

Mand Central incisor

43
Q

Most symmetrical tooth

A

mand centrals, very hard t tell the difference between #24 and #25. Also why the facial is the same size as the lingual embrasure–because it’s so symetrical

44
Q

First succedaneous teeth

A

mand centrals

45
Q

Has smallest facial and lingual embrasure

A

mand centrals

A

false, it is lingual

47
Q

A

Mand Central: centered
Mand Lateral: distal
