12

What is the biofilm life cycle?

Attachment
Growth
Detachment

13

A type of periodontal disease characterized by changes in the color, contour, and consistency of the gingival tissues

Gingivitis

14

Gingivitis that lasts a short period of time

Acute gingivitis

15

Gingivitis that lasts for months or years

Chronic gingivitis

16

Type of periodontal disease that is characterized by the apical migration of the JE, loss of CT attachment and loss of alveolar bone

Periodontitis

17

Movement of the JE apical to its normal location is termed

Apical migration of the JE

18

Bodies reaction to injury or invasion by disease producing organisms

Inflammation

19

Resorption of alveolar bone as a result of periodontitis

Alveolar bone loss

20

Bone loss fairly even, overall reduction in the height of alveolar bone

Horizontal bone loss

21

Less common pattern of bone loss and also called angular bone loss

Vertical bone loss

22

Bone resorption is uneven primarily on 1 tooth

Infra bony defect

23

Bowl shaped defect in the interdental alveolar bone with bone loss nearly equal on roots of 2 adjacent teeth

Osseous craters

24

Occurs on a multi rooted tooth when periodontal infection invades the area between and around the roots

Furcation involvement

25

A disease site that is stable with the attachment level of the JE remaining the same over time

Inactive disease site

26

A disease site that shows continued apical migration of the JE over time

Active disease site

27

A deepening of the gingival sulcus as a result of swelling or enlargement of gingival tissue

Gingival pocket

28

A pathologic deepening of gingival sulcus

Periodontal pocket

29

The movement of the cells of the JE from their normal position-- coronal to the CEJ-- to a position apical to the CEJ

Apical migration

30

Occurs when there is horizontal bone loss

Supra bony pockets

31

Occurs when there is vertical bone loss

Infrabony pockets

32

A systemic arrangement into groups or categories based on common attributes

Classification

33

Periodontal diseases involving inflammation of the gingiva in response to bacteria located at the gingival margin

Plaque induced gingival diseases

34

Most common form of periodontitis-- is a bacterial infection within the supporting tissues of the teeth

Chronic periodontitis

35

Characterized by a rapid loss of attachment and a less predictable response to periodontal therapy

Aggressive periodontitis

36

The study of health and disease within the total population and the risk factors influence health and disease

Epidemiology

37

Refers to the number of all cases (both old and new) of a disease that can be identified within a specified population at a given point in time
