Q

What is the cusp form of the mandibular canine?

A

Incisal ridge divided into mesial and distal slopes . Shorter more horizontal medial slope meets the longer, steeper distal ridge to form an obtuse angle at the cusp tip. Tip more lingually placed than maxillary canine.

Study These Flashcards
A

Two cusps, large buccal cusp and smaller palatal cusp separated by mesio-distal fissure. Mesial cusp slope longer than distal cusp slope

23
Q

What are the features of the mesial surface of the maxillary first premolar?

Study These Flashcards
A

Developmental canine groove extending across mesial marginal ridge to join canine fossa

24
Q

What is the root form of the maxillary first premolar?

Study These Flashcards
A

Two roots, buccal and palatal, pronounced mesial groove, root curves distally

25
What is the outline form of the mandibular first premolar?
Diamond shaped occlusal outline, mesio lingual portion of crown pushed in. Smallest crown of all premolars, outline not symmetrical
26
What is the cusp form of the mandibular first premolar?

30
Cusp outline of maxillary second premolar?
Two cusps, more equal in size than first | Short central fissure
31
What is the root form of maxillary second premolar?

33
What are the two types of cusp outlines you can find in mandibular second premolar?
Two cusp - round | Three cusp - square
34
Where is the tip located in the buccal cusp of mandibular second premolar?
Buccal side
35
What is the cusp form of the mandibular second premolar?
Three cusps more equal in size, two lingual and single buccal cusp (taller and wider mesiolingual than distolingual) Two cusp has central curving occlusal fissure around buccal cusp joining mesial and distal fossa, distal fossa being larger than mesial
36
What is the root form of mandibular second premolars?
SIngle conical root with rounded cross section, flattened slightly mesio-distally, curves distally, root longer in second
37
