22
Q

What are the 5 tooth surfaces?

A

facial, lingual, occlusal, mesial, distal

23
Q

mesial & distal

A

mesial - towards midline distal - away from midline

24
Q

buccal or labial surface

A

buccal - side of tooth touching cheek side (posterior)
labial - side of tooth touch lip area (anterior)

25
Q

lingual & Occlusal surface

A

lingual - side of tooth on the tongue side
occlusal - top surface of posterior teeth

26
Q

What are the anatomical features of the teeth?

A

contours, contacts, and embrasures

27
Q

Curved surface except when the tooth is fractured or worn
facial and lingual - protects gingiva
mesial and distal - normal contact and embrasures form

A

contours

28
Q

Mesail or distal surface of a tooth that touches the adjacent tooth in the same arch.
- prevents food from being trapped between teeth
-stabilizes dental arches

A

contacts

29
Q

“bulge” or widest point on a specific surface of the crown

A

Height of contour

30
Q

When two teeth in the same arch touch, their curvatures next to the contact areas form spaces called __________

A

Embrasures

31
Q

What is used only as a descriptive term to indicate specific locations?

A

Line & Point angles

32
Q

formed by the junction of two surfaces

A

line angle

33
Q

formed by the junction of three surfaces at one point

A

Point angle

34
Q

Each tooth surface is divided into imaginary ___________ to help identify a specific area of the tooth

A

thirds

35
Q

Division into thirds: Root of tooth

A

Apical third, middle third, & cervical third

36
Q

Division into thirds: Crown of tooth

A

Occlusocervical, mesiodistal, & buccolingual

37
Q

Relationship between maxillary and mandibular teeth when upper and lower jaws are fully closed and relationship between teeth in the same arch.

A

Occlusion

38
Q

Occurs when the jaws are closed in a position that produces maximal stable contact.

A

Centric Occlusion

39
Q

Abnormal or malpositioned relationships of maxillary teeth to mandibular teeth when they are in centric occlusion.

A

Malocclusion

40
Q
  • Used to describe and classify occlusion and malocclusion
A

Angles Classification

41
Q

An ideal mesiodistal relationship exists between the jaws and the dental arches

A

Class I Neutroclusion

42
Q

Mesiobuccal cusp of maxillary first molar occludes (by more than the width of the premolar) mesial to the mesiobuccal groove of mandibular first molar.

A

Class II Distoclusion

43
Q

What are the divisions of Class II Malocclusion

A

Division 1 : lips flat and parted, lower lip tucked behind upper incisors
Division 2: maxillary incisors are not in lavioversion

44
Q

Body of the mandible must be in a abnormal mesial relationship to the maxilla frequently give the appearance of protrusion of the mandible

A

Class III Malocclusion

45
Q

Anterior teeth are not designed to fully support the occlusal forces on the entire dental arch

A

Closure

46
Q

Occlusal surfaces of the posterior teeth do not form a flat plane

A

Curve of Spee

47
Q

Cross-arch curvature of the posterior occlusal plane

A

Palmer Notation System

49
Q

How are permanent teeth numbered?

A

1-32 maxilla right to left, down to mandibular left to right.
