Front 1

Describes the teeth in natural jawbone

Back 1

Dentition

Front 2

Includes 20 teeth in all
8 incisors
4 canines
8 molars

Back 4

Front 5

Includes 32 teeth in all
8 incisors
4 canines
8 premolars
12 molars

Back 5

Permanent dentition

Front 6

Dentition that has premolars

Back 6

Permanent Dentition

Front 7

Functions to bite and cut food duriing mastication

Back 7

Incisors

Front 8

Functions to pierce and tear during mastication

Back 8

Canines

Front 9

Functions to assist the molars in grinding food because of their broad surface and also assists the canines in piercing and tearing food during mastication

Back 9

Premolars

Front 10

Largest and storongest tooth in the dentition, function in grinding food during mastication, assisted by the premolars, due to the fact that they have a wide occlusal surfaces with prominent cusps.

Back 10

Molars

Front 11

Most widely used in America, its adaptable to electonic data transfer.
Uses A- T for the primary; starting with the Maxillary second molar and ending with the right Mandibular second molar
1-32 starting with the Maxillary thrid molar and ending with the Mandibular thrid molar.

Back 11

Universal Tooth Designation System

Front 12

Uses two-digit code, first digit indicates the quadrant and second digit indicates the tooth in that quadrant.
1st Digit---
Digits 1-4 used for the quadrant in the Permanent dentition
Digits 5-8 used for the quadrant number in the primary
2nd Digit----
1-8 permanent, starting from the midline
1-5 primary, starting from the midline

Back 12

International Standards Orginization Designation System (ISO)

Front 13

Commonly used in Orthodonics. In this system the teeth are designated with a right-angle symbol indicating the quadrants with the tooth number inside, similar to the ISo system.

Back 13

Palmer Method

Front 14

Begins with the eruption of the primary mandibular central incisors, occurs from 6 months- 6 years, jawbone growth is just beginning

Back 14

Primary Dentition Period

Front 15

Begins with the eruption of permanent mandibular first molar, occurs from 6-12 years, primary and permanent teeth, fastest and most noticeable jabone growth

Back 15

Mixed Dentition Period

Front 16

Beging with the shedding of the last primary tooth, after 12 years of age, usually only permanent teeth, slowest and least noticeable jawbone growth.

Back 16

Permanent Dentition Period

Front 17

What period is oral hygiene most difficult for patients because of the bacterial plaque biofilm retention?

Back 17

Mixed Dentiton Period/ Ugly Duckling Stage

Front 18

The way that the teeth in the maxillary and mandibular arch come into contact with each other

Back 18

Occlusion

Front 19

Tooth socket

Back 19

Alveolus

Front 20

Alveolus is located in this; tooth-bearing portion of each jawbone

Back 20

Alveolar process

Front 21

Each dental ARCH can be divided into

Back 21

Two Quadrants

Front 22

There are _______ quadrants in the entire mouth

Back 22

Four

Front 23

The correct sequence to describe a tooth is

Back 23

D-A-Q-T; Dentition, Arch, Quadrant, and Tooth Type

Front 24

Divide each dental arch into three portions according to their relationship to the midline

Back 24

Sextants

Front 25

The portion covered by enamel, remains mostly constant throughout, except for attrition and other physical wear.

Back 25

Anatomical Crown

Front 26

Portion of the anatomical crwn not covered by gingiva, its height is determined by the location of the gingival margin, the clinical crown of a tooth can change over time.

Back 26

Clinical Crown

Front 27

Portion of the root covered by cementum,

Back 27

Anatomical Root

Front 28

Portion of the anatomical root that is visible and subject to variability.

Back 28

Clinical Root

Front 29

Many surfaces of the roots have indentions or

Back 29

Root Concavities

Front 30

Imaginary line representing the long axis of a tooth

Back 30

Root Axis Line (RAL)

Front 31

Area between adjacent tooth surfaces

Back 31

Interproximal Space

Front 32

Where the crowns of adjacent teeth in the same arch physically touch

Back 32

Contact Area

Front 33

Crest of curvature, the greatest elevation of the tooth either incisocervically or occlusocervically.

Back 33

Height of Contour

Front 34

triangular-shaped space between two teeth created by the sloping away of the mesial and distal surfaces; when two teeth in the same arch come into contact their curvatures next to the spaces form spaces

Back 34

Embrasures

Front 35

Formed by the junction of two crown surfaces

Back 35

Line angles

Front 36

How many line angles do posterior teeth have?

Back 36

Eight- Mesiobuccal, Distobuccal, Mesiolingual, Distolingual, Mesio-occlusal, Disto-occlusal, bucco-occlusal, and linguo-occlusal.

Front 37

Anterior have ____ line angles.

Back 37

Six- Mesiolabial, Distolabial, Mesiolingual, Distolingual, labioincisal, and linguoincisal.

Front 38

Another way to determine a specific area of the crown, the junction of three crown surfaces.

Back 38

Point angle

Front 39

How many point angles does each tooth have?

Back 39

Four

Front 40

A crown can be divided into thirds.

Back 40

Cervical, middle, and Incisal thirds

Front 41

What defines the "face" of a tooth?

Back 41

Angles, height of contour, and spaces.

Front 42

Dental professionals must be careful to note the access to the proximal surfaces and interproximal space is more difficult than access to the facial and lingual surfaces.

Back 42

This access problem occurs for the patient during oral care as well as for the clinician during instumentation and restoration.

Front 43

Extraction allows both the

Back 43

anatomical crown and anatomical root to be viewed

Front 44

Fewer features can be seen clinically when portions of the CEJ and root are covered by gingiva and only the _______ is visible.
