A

maxillary lateral incisor

33
Q

what tooth sometimes has a groove called the palatalgingival groove that extends onto the crown

A

34
Q

what teeth are the cornerstones of the arches?

which teeth are the last teeth to be exfoliated(lost)

A

canines

37
Q

what are the maxillary canines pulp canals and horns

A

usually have a single pulp canal and a large pulp chamber; and the pulp chamber usually only has one pulp horn

38
Q

canine protected occlusion; relieves the posterior teeth from damaging occlusal forces

A

canine guidance

39
Q

what tooth resembles a pentagon

A

canine

40
Q

which tooth is divided into mesial and distal cusp ridges

canine

41
Q

a transitional tooth

A

canine

42
Q

which tooth is the only anterior teeth with a labial ridge

A

canine

43
Q

which tooth is wider labio-lingually than it is mesio-distally to offset the forces brought against it during function

A

maxillary canine

44
Q

which tooth has cusp slopes and not incisal edges

A

maxillary canine

45
Q

which slope is shorter on the labial view of the canines? (m or d)

A

mesial slope

46
Q

how is the cusp tip situated on the root axis line of a maxillary canine labial view?(centered or mesial/distal)

A

centered on the root axis line

47
Q

which contact point on the maxillary canines is closer to the cusp tip?

A

mesial contact point- located at junction of incisal and middle thirds

48
Q

distal contact point of maxillary canine is located more (incisal or cervically)

A

more cervically located- located at middle of middle third

49
Q

max lateral incisor: on mesial view, incisal edge is more____; on distal view, the incisal edge is more_____ to root axis line

A

labial; lingual

50
Q

for the maxillary canine on the lingual view, the mesial marginal ridge is (longer or shorter) than the distal marginal ridge

A

longer

51
Q

on the maxillary canine mesial view, the cusp tip is located (labially or lingual) to the root axis line– since this tooth overlaps the mandibular teeth when the jaws are closed

A

labially

52
Q

on the maxillary canines distal view, the longitudinal depression is more distinct on the mesial or distal side?

A

distal

53

in the incisal view of maxillary canines, which bulk is greater? (mesial or distal)

A

distal

55
Q

why is the distal bulk of the maxillary canine on the incisal edge greater than the mesial bulk?

to make contact with the maxillary first premolar
