Q

What is necrotizing stomatitis?

A

The most severe condition with severe tissue necrosis that extends beyond the gingival tissues in the cheeks, tongue and palate along with bone destruction and osteitis (inflammation of the bone).

Q

What is the treatment for necrotizing gingivitis?

A

Anti-inflammatory for pain
Chlorhexidine or hydrogen peroxide rinse
Removal of pseudo membrane
Debridement
Avoid alcohol, drugs, smoking
OHI and nutrition counselling
Antibiotics may be prescribed

17
Q

Treatment for necrotizing periodontitis

A

Referral to peridontist

18
Q

Treatment for necrotizing stomatitis

A

Immediate referral to an oral pathologist and/or oral surgeon

19
Q

What are examples of systemic diseases affecting the periodontium?

A

Rare disorders (down symdrome)
Oral cancer
Diabetes
Osetoporosis

20
Q

What are the mucogingival deformaties and conditions around the teeth?

A

Gingival recession
Lack of keratinized gingiva
Decreased vestibular depth
Absent frenum/muscle position
Gingival excess
Abnormal colour

21
Q

What is the most common of the mucoingival deformaties and conditions around the teeth?

A

Gingival recession

22
Q

What was the most commonly used classification system for recession of the margin but has recently been replaced?

A

Miller Classifcation System for Recession of Gingival Margin

23
Q

What is the current classification system for recession?

A

Cairo Classification System for Recession of Gingival Margin

24
Q

How does the Cairo classification system for recession work?

A

It is based on CAL measurements at buccal and interproximal sites

25
Q

What is RT1?

A

Gingival recession with no loss of interproximal attachment

26
Q

What is RT2?

A

Gingival recession associated with interproximal attachment loss (interproximal loss is less than or equal to the buccal loss). Periodontitis horizontal bone loss.

27
Q

What is RT3?

A

Gingival recession associated with interproximal attachment loss (interproximal loss is greater than buccal loss). Periodontitis infrabony defect.

28
Q

What are the localized dental prosetheses-related factors?

A

Partial denture
Crown/bridge

29
Q

What is the space occupied by the JE and CT attachment fibers?

A

Supracrestal Tissue Attachement (Biological Width)

30
Q

Impingement on the supracrestal tissues attachment will cause

A

Chronic gingival inflammation and bone loss

31
Q

A crown placement of ___mm coronal to alveolar crest is paramount in maintaining gingival health.

A

2mm

32
Q

What can happen if the crown margin is closer than 2mm to the alveolar crest?

A

Bone resorption

33
Q

What occurs if margins of restorations encroach upon the zone of soft tissue occupied by the JE and conntective tissue attachment fibers?

A

Supracrestal tissue attachment violation

34
Q

What is a localized accumulation of pus in a peridontal pocket?

A

A periodontal abscess

35
Q

What can trigger an endo-periodontal lesion?

A

Carious or traumatic lesion that affects both the pulp and periodontium

36
Q

What is traumatic occlusal force or excessive occlusal trauma?

A

Force that exceeds that adaptive capacity of the periodontium or teeth

37
Q

True or False: Local risk factors can be either acquired or anatomical

A

True

38
Q

What are some aquired local risk factors?

A

Calculus
Restoration overhangs
Poorly contoured restorations

39
Q

What are some anatomical local risk factors?

A

Malpositioned teeth
Root grooves
Concavities
Furcations
