Flashcards in Exam 2; Dental Plaque Induced Gingivitis Deck (33):
1

What are some examples of gingival diseases modified with systemic factors

associated with endocrine system
puberty induced
menstrual cycle
pregnancy
diabetes
associated with blood; leukemia

2

What are two gingival diseases modified by medications

gingival enlargements
oral contraceptive associated gingivitis

3

What is a gingival disease modified by malnutrition

ascorbic acid deficiency gingivitis

4

What is the term of gingivitis around implants

peri-mucositis

5

What are the 6 common characteristics to all gingival diseases

1. signs and symptoms limited to the gingiva
2. presence of dental plaque
3. clinical signs of inflammation
4. clinical signs and symptoms associated on a periodontium with NO attachment loss or on a stable nut reduced periodontium
5. reversibility of disease by removing the etiology
6. possible role as a precursor to attachment loss

6

what are 5 common clinical changes from health to gingivitis

color
texture/edema
bleeding
exudate
plaque

7

What is the color of severely inflamed gingiva

red and cyanotic; no oxygen = purple/blue

8

Where does the change of color of inflamed gingiva begin

starts in the interdental papilla and gingival margin and then spreads to the attached gingiva

9

This occurs with increasing inflammation due to dilation and engorgement of the capillaries and the thinning or ulceration of the sulcular epithelium

gingival bleeding

10

Spontaneous bleeding occurs in acute/severe gingival disease and may be related to what

systemic health problems

11

Healthy gingiva is firm and resilient, when inflamed, what three things occur

increased ECF and exudate
degeneration of connective tissue and epithelium
engorged connective tissue and thinning of epithelium

12

Chronic inflammation of the gingiva can induce what

fibrosis and epithelial proliferation

13

Healthy gingiva has a dull surface texture with stippling present in some cases, when inflamed, what three things occur

loss of stifling
smooth and shiny, if exudate changes occur
firm and modular, if fibrotic changes occur

14

In healthy gingiva, it is scalloped with gingiva filling the interdental spaces, but with inflammation what occurs

knife edge gingival adaptation or loose gingival margins
in some cases, clefts or festoons may develop

15

What is the primary etiologic factor of gingivitis

bacterial plaque

16

What are four secondary etiological factors of gingivitis

calculus
marginal deficiencies in restorations and rough surfaces
malocclusion
tooth/root anomalies

17

Describe the biologic width

a minimun digestion of 3mm coronal to the alveolar crest, to permit healing and proper restoration

18

Periodontitis starts with what

gingivitis!
but gingivitis does not always progress into periodontitis

19

How does gingivitis lead to periodontitis

progression of the inflammatory process to the underlying connective tissue attachment and PDL, can be recurrent

20

True or False
Recurrent inflammation may be confined to the gingival tissues and may not cause further attachment loss, but still diagnosed as recurrent periodontitis

True

21

Gingival disease are modified by what

endocrine factors

22

What causes pregnancy associated gingivitis

exaggerated localized host response modulated by levels of endogenous hormones causing changes in the microbiota; 2nd trimester

23

While clinically detectable changes do not seem to be associated with the menstrual cycle, what does

there has been shown to be a 20% increase in GCF

24

This commonly arises from the proximal gingival tissues and has a pedunculated base; is a highly vascularized mass of granulation tissue

pyogenic granuloma of pregnancy

25

What can cause some gingival disease modified by malnutrition

deficiency in vitamin C
lack of vitamins A, B2, and B12

26

What are some systemic conditions that can modify gingival diseases

diabetes mellitus
leukemias
thrombocytopenia
cyclic neutropenia

27

What are 3 commonly used drugs that are associated with gingival overgrowth

anticonvulsants (phenytoin)
immunosuppressants
calcium channel blocking agents

28

This can cause pain, ulceration and necrosis of the interdental papilla, and bleeding

necrotizing ulcerative gingivitis

29

What are three predisposing factors for NUG

systemic diseases like ulcerative colitis, blood dyscrasias, and nutritional deficiency states
abnormalities of WBC function
AIDS

30

What are the differences in the cause of NUG and primary herpetic gingivostomatitis (PHS)

NUG = bacteria
PHS = herpes simplex

31

What are the differences in symptoms between NUG and primary herpetic gingivostomatitis (PHS)

NUG = ulceration and necrotic tissue, yellowish-white plaque
PHS = multiple vesicles which burst leaving small round fibrin covered ulcers

32

What are the differences in duration of NUG and primary herpetic gingivostomatitis (PHS)

NUG = 1-2 days if treated
PHS = 1-2 weeks

33

What are the differences in contagious-ness of NUG and primary herpetic gingivostomatitis (PHS)

NUG = No
PHS = Yes
