35
Q

Periapical

A

Anything surrounding the apex

36
Q

Cervix

A

The narrow area of the tooth where the crown and the root meet (cervix means neck)

37
Q

Cementoenamel junction

A

is formed by the enamel of the crown and the cementum of the root. Also known as the cervical line or the cementoenamel junction

38
Q

Enamel

A

Makes up the anatomic crown of the tooth, and is the hardest material of the body; similar to bone in its hardness and mineral content

39
Q

Enamel Prisms

A

Also known as enamel rods; What enamel is composed of; Extends from the surface of the tooth to the dentinoenamel junction.

40
Q

Dentin

A

Mineralized tissue that is harder than bone and cementum but not as hard as enamel. Makes up the primary portion of the tooth structure and extends almost the entire length of the tooth; color tends to darken as we age

41
Q

Dentinal Tubules

A

Microscopic canals that make up dentin; Extend from the exterior surface, where the dentin joins the enamel, then these tubules form a direct passage for invading bacteria into the pulp.

42
Q

Dentinal Fiber

A

Transmits pain to the pulp

43
Q

Pulp

A

Vascular tissue filling the interior cavity and root canals of a tooth

44
Q

Coronal Pulp

A

Portion of the pulp that lies within the crown portion of the tooth; It includes the pulp horns. which are extensions of the pulp that project toward the cusp tips and incisal edges.

45
Q

Cementum

A

Not as hard as either enamel or dentin, protects the root of the tooth and joins the enamel at the CEJ; Light yellow shade that is somewhat light than the color of dentin and darker than enamel.

46
Q

Periodontium

A

Supports the teeth in the alveola bone and consists of cementum, alveolar bone, and the periodontal ligaments. These tissues also protect and nurish the teeth.

47
Q

Periodontal ligament

A

dense connective tissue organized into groups of fiber that connect the cementum covering the root of the tooth with the alveolar bone of the socket wall.

48
Q

Embrasure

A

A triangular space near the the gingiva between the proximal surfaces of two adjoining teeth.

49
Q

Occlusion

A

the contact between the maxillary and mandibular teeth in all mandibular positions and movements.

50
Q

Fossae

A

Indentations or grooves.

51
Q

cusps

A

Raised areas

52
Q

Edentulous

A

Means without natural teeth and is used to describe the condition where the permanent teeth have been lost.

53
Q

Primary dentition

A

Childs teeth that fall out

54
Q

Permanent dentition

A

permanent adult teeth

55
Q

Mixed dentition

A

When both primary and permanent teeth are in the mouth.

56
Q

Eruption

A

The movement of a tooth through the bone and gingival tissue

57
Q

Exfoliation

A

The normal process by which primary teeth are shed; During this process the root of the primary teeth is resorbed

58
Q

A

Something that is on a higher level

65
Q

Innervation

A

Another term for nerve supply

66
Q

Mucous membrane

A

specialized tissue that lines the inside of the mouth

67
Q

Nasopalatine nerve

A

passes through the incisive foramen, supplies the tissue palatal to the maxillary anterior teeth.

68
Q

Foramen

A

An opening in a bone through which blood vessels, nerves, and ligaments pass

69
Q

Vestibule

A

Space between the teeth and the inner mucosal lining of the lips and cheeks.

70
Q

Oral cavity proper

A

Space on the tongue side within the upper and lower dental arches.

71
Q

Papillae

A

tiny projections; inside the papillae are sensory organs and the nerves for both taste and touch.

72
Q

Dorsum

A

Consists of the superior (upper) and posterior roughened aspects of the tongue and is covered with small papillae of various shapes and colors.

73
Q

Frenum

A

narrow band of tissue that connects two structures.

74
Q

Salivary glands

A

produce saliva and lubricates and cleans the oral cavity and helps with digestion

75
Q

Hard and Soft Palates

A

Serve as the roof of the mouth, and they separate the mouth from the nasal cavity

76
Q

lining Mucosa

A

covers the inside of the cheeks, vestibule, lips, ventral surface of the tongue, and soft palate, is delicate, thin, and easily injured.

77
Q

masticatory mucosa

A

covers the gingivae (guns), hard palate, and dorsum of the tongue, is firmly attached to the bone, is very dense, and designed to withstand the vigorous activity of chewing and swallowing food.

78
Q

gingivae

A

the tissues that surround the teeth (gums); masticatory mucosa that covers the alveolar processes of the jaws and surrounds the necks of the teeth
