Flashcards in Dental Terminology - Anatomic Terms Deck (59):
1

alveolar bone

cancellous bone directly surrounding the tooth roots

2

alveolar crest

the ridge of bone between two adjacent teeth or between the roots of a tooth

3

alveolar mucosa

less densely keratinized gingival tissue covering the bone

4

alveolus

the cavity or socket in either jaw bone that surrounds and supports the root of the tooth

5

anterior teeth

the canine and incisor teeth

6

apex

terminal portion of the root

7

apical delta

the diverging branches of the root canal at the apical end of the tooth root

8

apical foramen

the opening in the apex of the root through which nerves and vessels pass into the root canal

9

attached gingiva

the gingiva that extends from the free gingival groove to the mucogingival line

10

attachment apparatus

the periodontal ligament, cementum, and alveolar bone that holds the tooth in place

11

canine tooth

large single root tooth designed for tearing and grasping

12

carnassial tooth

shearing tooth upper P4 and lower M1 in the dog and cat

13

cementoenamel junction

found at the neck of the tooth where the enamel and the cementum meet

14

cementum

bony layer covering the root surface

15

cingulum

the cervical third of the palatal surface of the anterior teeth

16

crown

the portion of the tooth covered with enamel

17

cusp

tip or pointed prominence on the occlusal surface of the crown

18

deciduous teeth

teeth of the primary dentition ("baby teeth")

19

dental arch

formed by the curve of the crowns of the teeth in their normal position or by the residual ridge if the teeth are missing

20

dental quadrant

half of each dental arch when divided at the midline

21

dentin

the main component of the tooth, consists of multiple tubules that extend from the pulp to its outer surface. the tubules contain sensory nerve fibers that register various degrees of pain. Harder then bone, dentin is covered by enamel on the crown and by cementum on the root.

22

diastema

the space between two adjacent teeth that are not in contact with each other in an arch

23

enamel

the hard shiny outer layer of the crown composed of hydroxyapatite crystalline components

24

free gingiva

portion of the gingiva not directly attached to the tooth that forms the gingival wall of the sulcus

25

epithelial attachment

tissue attaching the gingiva to the tooth

26

free gingival groove

on the surface of the gingiva a slight concavity or line seperating free from attached gingiva

27

free gingival margin

the free edge of the gingiva on the tooth surface

28

furcation

space between the tooth roots where they join the crown

29

gingiva

soft tissue surrounding the teeth

30

gingival sulcus

the normal space created by the free gingiva and the tooth

31

gnathic

referring to the jaw

32

halitosis

foul, offensive or unpleasant breath

33

incisal edge

the cutting edge of the incisors

34

incisor

small anterior tooth with a single root

35

infrabony pocket

a periodontal pocket in the alveolar bone

36

interdental

the area between the proximal surfaces of adjacent teeth in the same arch

37

interproximal

between adjoining surfaces of the teeth in the same arch

38

interradicuar

between roots of multirooted teeth

39

juga

the depressions between the ridges of bone formed by roots in the alveolar process on the mandible or the premaxilla and maxilla

40

lamina dura

the dense cortical bone forming the wall of the alveolus next to the tooth. it appears on a radiograph as a white line next to the dark line of the periodontal ligament

41

lateral or accessory canal

small canal leading from the root canal to the outer surface of the toot

42

line angle

the imaginary intersection of two tooth walls

43

mental foramen

openings in the mandible through which nerves and vessels pass

44

molar

large multicusp teeth designed for grinding upper (2) molars have three roots and lower (3) molars have two roots in dogs

45

mucogingival line

definite line of demarcation where the attached gingiva and alveolar mucosa meet

46

neck (cervical line)

the junction of the crown and root

47

odontoblast

the cells in the pulp that produce dentin

48

palate

the structure that separates the oral and nasal cavities

49

periodontal ligament

a network of fibers connecting the tooth to the bone

50

posterior teeth

the premolar and molar teeth

51

premolar

the teeth distal to the canine and mesial to the molars with one to three roots

52

primary teeth

the first teeth to erupt, eventually replaced by adult teeth

53

proximal

the surface of a tooth that is adjacent to another tooth

54

pulp

soft tissue component of the tooth consisting of blood and lymphatic vessels, nerve tissue and loose connective tissue

55

pulp chamber

portion of the crown containing the pulp

56

radicular

pertaining to the root

57

root

the portion of the tooth normally covered by cementum

58

root canal

portion of the root containing the pulp

59

ruga palatina

the irregular ridge in the mucous membrane covering the anterior part of the hard palate
