Mean age of NPD in industrialized countries is

Answer 11

22-24 years old

Question 12

Mucogingival conditions are assessed through clinical examinations for

Recession
Frenum pulling of gingiva
Width of attached gingiva

Question 13

Attached gingiva formula: to calculate the width of attached gingiva at a specific site

Answer 13

Measure the width of the gingiva (from margin to Mucogingival junction)
Subtract the probing depth from total width

Maxillary and mandibular frenum pull
Buccal frenum
Recession
Bruxism
Ortho
Age
Lip/tongue piercing

Question 17

Gingival phenotype refers to

Answer 17

Clinical observation of variation in the thickness and width of facial keratinized tissue

Question 18

Periodontal biotype describes

Answer 18

Individual differences in bone and soft tissue that make up the periodontium as well as tooth form

Question 19

3 main biotypes

Answer 19

Thin scalloped
Thick flat
Thick scalloped

Question 20

Research shows that plaque associated inflammation may result in

Answer 20

Deep periodontal pockets with a thick flat biotype and into gingival recession in a thin scalloped biotype

Question 21

Thin scalloped biotype is slender

Answer 21

Triangular shaped tooth crowns
Clear thin delicate gingiva /thin alveolar bone

Question 22

Thick flay biotype; what shape tooth crowns

Answer 22

Square shaped
Thick fibrotic gingiva: thick alveolar bone

Question 23

Thick scalloped biotype has pronounced gingival scalloping; what kind of fibrotic tissue

Answer 23

Thick fibrotic tissue
Narrow zone of keratinized tissue

Question 24

Gingival recession is the most common Mucogingival deformity and is characterized by

Answer 24

Apical displacement of gingival margin with respect to CEJ
-attachment loss with root exposure

Question 25

Risk factors of gingival recession

Answer 25

Thin periodontal biotype Absence of attached gingiva Reduced thickness of alveolar bone due to abnormal tooth position

Question 26

-Marginal recession but does not extend to MGJ -no loss of bone or soft tissue in interdental area -Complete root coverage is obtainable What miller recession classification?

Answer 26

Class I gingival recession

Question 27

Class II miller gingival recession same as class one miller except

Answer 27

Marginal recession extends beyond MGJ

Question 28

-marginal recession extends beyond MGJ -bone and soft tissue loss in interdental - may have tooth malpositioning that prevents coverage of certain roots Miller classification?

Answer 28

Class III gingival recession

Question 29

T/F. Class IV miller gingival recession is the same as class III miler just more extreme and crater like

Answer 29

True

Question 30

RT1 gingival recession with no loss of Interproximal attachment. Most likely associated with

Answer 30

Traumatic tooth brushing

Question 31

RT2 gingival recession with loss of Interproximal attachment most likely associated with

Answer 31

Periodontitis associated horizontal bone loss

Question 32

RT3 same as RT2 but with Interproximal attachment loss greater than buccal loss associated with

Answer 32

Infrabony defects

Question 33

Aberrant (abnormal) frenum can contribute to a

Diastema Recession Muscle tension

Question 34

Non carious cervical lesions (NCCL’S) Are defined as dental tissue lost at or near the CEJ and not related to?

Answer 34

Tooth decay

Question 35

Traumatic occlusal forces are forces that exceeds?

Answer 35

Adaptive capacity of periodontium and or the teeth (Excessive wear, occlusal trauma, fracture)

Question 36

Primary occlusal trauma occurs in the presence of?

Answer 36

Normal bone level Normal attachment level Excessive occlusal forces

Question 37
