Q

This is the part of the crown that is covered with enamel

A

Anatomical Crown

28
Q

This is part of the crown that is the portion of the anatomical crown that is visible clinically. It is what you see when you look in the mouth.

A

Clinical Crown

29
Q

This is the portion of the root that is covered with cementum

A

Anatomical Root

30
Q

This is the portion of the root that is part of the anatomical root that is actually embedded in the jaw. In a patient with advanced bone loss, the clinical root may be reduced in size.

A

Clinical Root

31
Q

This is the line that separates the anatomical crown from the anatomical root

A

Cervical line

32
Q

The cervical line is the junction between which two tissues? Therefore, it is also called the… Also called the cervix (neck) of the tooth

A

Enamel and Cementum cemento-enamel junction (CEJ)

33
Q

This is the space of the tooth which contains the pulp or ‘nerve’ of the tooth

A

Pulp cavity

34
Q

The pulp cavity has two portions, one for the crown and one for the root. What are they?

A

Coronal and radicular (usually called root canal)

35
Q

The pulp cavity enters the tooth from the bottom through the ____ of the root

A

Apex of the root

36
Q

This dental tissue is the protective outer surface of the anatomic crown. It is 96% mineral and is the hardest tissue in the body

A

Enamel

37
Q

This dental tissue is located in both the crown and root, makes of the bulk of the tooth beneath the enamel and cementum.

A

Dentin

38
Q

Dentin lines what part of the tooth?

A

Pulp Cavity

39
Q

This dental tissue is the central, innermost portion of the tooth. It has formative, sensory nutritive and reparative functions during the life of the tooth

A

Pulp

40
Q

This dental tissue covers the surface of the anatomic root. It facilitates anchorage of the tooth in its bony socket (the alveolus) It is really similar to what other body tissue?

A

Cementum Bone

41
Q

An imaginary line that bisects the dental arch at the center.

A

Midline

42
Q

Toward the center midline of the dental arch Away from the center midline The surface of a tooth that is toward another tooth in the arch

A

Mesial Distal Proximal (interproximal)

43
Q

Toward the cheeks or lips

A

Facial

44
Q

Facial surface of anterior teeth (toward the lips)

A

Labial

45
Q

Facial surface of posterior teeth (toward the cheeks)

A

buccal

46
Q

Toward the tongue

A

Lingual

47
Q

The biting surface; the surface that articulates with an antagonist tooth in an opposing arch

A

Occlusal

48
Q

The cutting edge of anterior teeth (note: posterior teeth don’t have incisal surfaces, they just grind. Use occlusal for the surface)

A

Incisal

49
Q

Contact

A

A point or area where one tooth is in contact (touching) its neighbor

50
Q

Review location on a tooth slide

A

JUST DO IT!

51
Q

A point or peak on the occlusal surface of molar and premolar teeth - an elevation on the surface of the crown of a tooth making up a divisional part of the occlusal surface

A

Cusp

52
Q

A bulge or elevation on the lingual surface of incisors or canines. It makes up the bulk of the cervical third of the lingual surface (booty of the tooth). Its convexity mesiodistally resembles a girdle encircling the lingual surface at the cervical

A

Cingulum (only on the anterior teeth)

53
Q

One of the primary centers of formation on the development of the crown of the tooth. Cusps and mamelons are representative of them

A

Lobes

54
Q

Lobes seen on anterior teeth, only the incisors. Any of three rounded protuberances.

A

Mamelons

55
Q

Rounded borders of enamel that form the margins of the surfaces of premolars and molars, mesially and distally, and the mesial and distal margins of the incisors and canines lingually

A

Marginal Ridge

56
Q

Ridges that descend from the tips of the cusps molars and premolars toward the central groove of the occlusal surface

A

Triangular Ridges

57
Q

These ridges are created when a buccal and lingual triangular ridge join. It is the union of two triangular ridges crossing transversely across the surface of a posterior tooth.

A

Transverse ridges

58
Q

These ridges are seen on maxillary molars and are a companion feature to the distal oblique groove Also known as the elevation in the enamel that runs obliquely across the occlusal surface of a maxillary molar

A

Oblique Ridges

59
Q

This fossae is found on the occlusal surface of a molar. They are formed by the converging of ridges terminating at a central point in the bottom of a depression where there is a junction of developmental grooves.

A

Central Fossa

60
Q

This fossa is the sulcus on the lingual surface of incisors

A

Lingual Fossa

61
Q

This fossa is found on molars and premolars on the occlusal surfaces or distal to marginal ridges

A

Triangula fossae

62
Q

This is a small pinpoint depression located at the junction of developmental grooves or at the terminals of these groups. A pit is often the site of the onset of dental decay.

A

Pit Note: there are buccal or central pits

63
Q

This groove/fissues is a sharply definted, narrow or linear depression formed during tooth development and usually separating lobes or major portions of a tooth. Major grooves are named according to their location

A

Developmental groove

64
Q

A groove/fissure that is a shallow linear depression but is usually less distinct and is more variable than a developmental groove and does not mark the junction of primary parts of a tooth.

A

Supplemental groove

65
Q

When two teeth in the same arch are in contact, their curvatures adjacent to the contact areas form spillway spaces called….

A

Embrasures

66
Q

Review the types of embrasures

A

Facial (buccal/labial)* Occlusal or incisal Lingual* Gingival (interproximal space
