Cervical Third of crown and roote

32
Q

Where is the lingual height of contour?

Cervical one third of the crown

Cervical one third on the cingulum

33
Q

On the maxillary canine, where is the mesial contact point?

From the distal aspect of the maxillary canine, the cervical crown usually has a CONVEXITY/CONVACITY and is more CONVEX/CONCAVE than the mesial crown surface

A

Concavity, concave

35
Q

On the maxillary canine, is the distal marginal ridge more likely to be irregular or regular in form compared to the mesial marginal ridge?

A

More irregular

36
Q

On the distal aspect of the maxillary canine, how is the contact situated when compared to the mesial contact?

A

It is situated more cervically, in the middle of the middle third of the crown

(makes sense because it’s more like the posterior teeth)

37
Q

From the incisal view, is the maxillary canine thicker mesiodistally or labiolingually?

A

Labiolingually

38
Q

From the incisal view, the tip of the cusp of the maxillary canine is towards the ____ and ____

A

Labial and mesial

39
Q

For the maxillary canine, on radicular perspectives. the root is thicker faciolingually or mesiodistally?

A

Thicker faciolingually than mesiodistally

40
Q

The root of the maxillary canine may have a curve in the apical one third of the root, which may be in a mesial or distal direction, but usually in a ____ direction

A

Distal direction

41
Q

Are all roots of maxillary canines completely convex?

The facial surface of the root is almost parallel to the _______ ______ of the tooth

A

No, some are concave which allows bone to grow into the depression, anchoring it (called mesial and distal development root depression)

Long axis

42
Q

In the radicular aspect of the maxillary tooth, root shape contribute to the formation of the….

A

Canine eminence

43
Q

These are the 4 functions of pulp chambers and canals in canines

A

Formative, Nutritive, Sensory, and Defensive

44
Q
  1. This function of the pulp is its control of the formation of dentin during the developmental period.
  2. This function of the pulp is its control of blood flow to the tooth
  3. This function is the complex system which is responsible for pain
  4. This function is the formation of reparative dentin in response to any form of irritation: mechanical, thermal, chemical, or bacterial
A
  1. Formative
  2. Nutritive
  3. Sensory
  4. Defensive
45
Q

This aspect of the pulp is the coronal pulp located in the anatomical crown

A

Pulp Chamber

46
Q
  1. This aspect of the pulp is the projections of the pulp chambers towards the cusp tips or lobes. They ae located within the pulp chamber.
  2. They are more prominent in OLDER/YOUNGER patients
A
  1. Pulp Horns
  2. Younger
47
Q

This part of th epulp is the radicular pulp located in the anatomical root

A

Root Canal

48
Q

This part of the pulp is the opening at or near the apex. It is a passageway for lymph vessels, nerve, and connective tissue elements

A

The Apical Foramen

49
Q

This part of the pulp are the branches of pulp which extend laterally

A

Lateral Canals

50
Q

It is essential to be aware of the location and size of the pulp cavities during operative procedures to prevent unnecessary ______

It is essential for endodontic procedures to adequately access preparation, locate canals, and avoid _______

A

Exposure

Perforation

  4. Apically (duh)
52

What is the shape of the crown when viewed from the labial side?

A

It has a nearly straight mesial aspect of the crown

Trapezoidal

56
Q

For the mandibular cusp ridges, which is shorter, the mesial or the distal?

A

The mesial is shorter, distal is about twice as long

57
Q

On the mandibular canine, which slopes cervically at a greater angle?

A

The distal cusp ridge

58
Q

For the mandibular canine, on the lingual aspect, how do the marginal ridges and cingulum compare to the maxillary canine?

A

They are both less prominent

59
Q

How does the lingual portion of the crown of the mandibular canine compare to the other teeth around it?

A

Resemble the form of the lingual surfaces of the mandibular lateral incisors

60
Q

On the mandibular canine, how does the lingual surface compare to the maxillary canine?

Lingual

(to allow the maxillary to be more facial/labial)
