Acquired deformities

Answer 2

defects seen in the periodontium related to recession, gingival enlargement, or personal habits that may or may not require therapeutic intervention

Question 3

Aggressive periodontitis

Answer 3

periodontal disease that progresses exceedingly rapidly with massive bone loss

Question 4

Antibiotic therapy

Answer 4

treatment of disease by the local or systemic administration of antibiotics

Question 5

Bone loss

Answer 5

decrease in periodontal bone structure or strength, usually as a result of inflammation

Question 6

Chronic periodontitis

Answer 6

most common form of periodontal disease, with a long slow course

Clinical attachment loss

Answer 7

measurement that documents increases in the distance from the cementoenamel junction to the apical depth of the periodontal pocket

Question 8

Developmental anomalies

Answer 8

aberrations or deviations from the normal pattern of development

Question 9

Enzyme suppression therapy

Answer 9

promising treatment for periodontitis involving antimicrobial doses of doxycycline to produce enzyme inhibition unrelated to antibiotic activity and enhance the results of scaling and root planing in patients with moderate periodontal disease

Question 10

Episodic periodontal disease

Answer 10

periodontal disease exhibiting occasional bursts of activity followed by periods of remission

Question 11

Gingival enlargements

Answer 11

localized deepening of the gingival crevice of 2 mm or more caused by swelling or increase in the volume of the gingiva

Question 12

Intrabony pocket

Answer 12

pocket that extends apically from the crest of the alveolar bone, also called infra bony pocket

Question 13

Necrotizing ulcerative gingivitis

Answer 13

inflammation of the gingival characterized by necrosis of the interdental papillae, ulceration of the gingival margins, appearance of the pseudomembrane, pain, and a fetid odor

Question 14

Necrotizing ulcerative periodontitis

Answer 14

most appropriate term for the massive tissue-destroying process that is an extension of acute necrotizing ulcerative gingivitis

Question 15

Pathogenesis

Answer 15

course of an illness or condition, from its origin to manifestation and outbreak

Question 16

Pathogenicity

Answer 16

ability to cause disease

Question 17

Periodontal abscess

Answer 17

acute, localized, purulent infection of the periodontium

Question 18

Periodontal bone loss

Answer 18

loss of crystal alveolar bone through the inflammatory process

Question 19

Periodontal disease

Answer 19

any of a group of inflammatory and infectious diseases affecting the gums and supporting tissues of the teeth

Question 20

Periodontal pocket

Answer 20

pathologically depended gingival sulcus

Question 21

Periodontitis

Answer 21

alterations in the periodontium resulting from inflammation or any chronic progressive disease of the periodontium

Question 22

Prepubertal periodontitis

Answer 22

very rare condition among children that may be localized or generalized and may affect both the primary and secondary dentitions; usually involves severe gingival inflammation, rapid bone loss, and early tooth loss

Question 23

Pseudopockets

Answer 23

pocket formed by gingival hyperplasia and edema without apical migration of the epithelial tissue

Question 24

Rapidly progressing periodontitis

Answer 24

periodontitis that occurs in young adults, usually between 20 and 30 years old, and causes rapid and severe gingival inflammation

Question 25

Refractory periodontitis

Answer 25

periodontal disease that does not respond to appropriate treatment

Question 26

Risk factor

Answer 26

exposures, behaviors, and characteristics associated with a disease

Question 27

Site specific

Answer 27

localized to a particular area

Question 28

Suprabony pocket

Answer 28

periodontal pockets that occur above the crest of the alveolar bone

Question 29

Suppuration

Answer 29

formation and discharge of pus

Question 30

What is the principal etiologic agent of periodontitis?

Answer 30

dental plaque biofilm

Question 31

Gingivitis and periodontitis share all the following characteristics EXCEPT one. Which one is the EXCEPTION?

Answer 31

alveolar bone loss

Question 32

All of the following conditions contribute to the retention of dental plaque biofilm EXCEPT one. Which one is the EXCEPTION?

Answer 32

cigarette smoking

Question 33

Chronic periodontitis is

Answer 33

not treatable with antibiotics

Question 34

Localized aggressive periodontitis in its juvenile form is associated with all of the following characteristics EXCEPT one. Which one is the EXCEPTION?

Answer 34

Neutrophil defect

Question 35

Which type of bacteria is associated with localized juvenile periodontitis?

Answer 35

A. actinomycetemcomitans

Question 36

Refractory periodontitis never responds adequately to treatment and the disease essentially continues unabated because of the failure of nonsurgical therapy

Answer 36

The statement is correct, but the reason is NOT correct

Question 37

Cigarette smokers are more likely to have tooth loss and impaired healing than non smokers. It is important for patients to refrain from smoking during periodontal therapy

Answer 37

Both statements are true
