Q

NUG Clinical Features

A

Interdental papillae are highly inflamed, edematous, and hemorrhagic.
Papillae are blunted with crater-like necrosis covered by grey pseudomembrane.
Can lead to loss of attachment

Q

Granulomatous Gingivitis Treatment

A

Surgically excise foreign body

If no foreign body, evaluate for other diseases

17
Q

Desquamative Gingivitis

A

Gingival epithelium that sloughs spontaneously or with minor manipulation

18
Q

Desquamative Gingivitis Epidemiology

A

Female

> 40 yo

19
Q

Desquamative Gingivitis Clinical Features

A 
Gradual involvement
More facial than lingual
Smooth erythema
Loss of stippling
Painful
Can have blisters
20
Q

Desquamative Gingivitis Histology

A

Lichen planus or pemphigoid

21
Q

Desquamative Gingivitis Treatment

A

Clean area
Doxycycline
Immunosupressants

22
Q

Drug Related Gingival Hyperplasia

A

Abnormal growth of gingival tissues secondary to systemic medication due to an increased production of ECM (collagen)
Most common with cyclosporine and phenytoin
Associated with poor dental hygiene???

23
Q

DRGH Epidemiology

A

25 and younger

24
Q

DRGH Clinical Features

A

Enlargements start in interdental papillae and spread
Dark red, bleeds easily, can ulcerate
Can interfere with speech and mastication

25
Q

DRGH Histology

A

Elongated rete ridges

Increased collagen

26
Q

DRGH Treatment

A

Discontinue medication
If med can’t be stopped - professional evaluations and home plaque control
Folic Acid

27
Q

Gingival Fibromatosis

A

Hyperplasia of gingiva

28
Q

Gingival Fibromatosis Epidemiology

A

Familial or idiopathic
Begins < 20 yo
May be associated with hypertrichosis, epilepsy, and mental retardation

29
Q

Gingival Fibromatosis Clinical Features

A

Enlarged gingiva
Normal color
Smooth surface

30
Q

Gingival Fibromatosis Histopathology

A

Dense hypocellular
Hypovascular tissue
Absent inflammation

31
Q

Gingival Fibromatosis Treatment

A

Gingivectomy
Oral hygiene
Sometimes tooth extraction

32
Q

Periodontitis

A

Inflammation of gingival tissue with associated loss of bony attchment and support
Risk factors: smoking, diabetes, genetics

33
Q

Periodontitis Bacteria

A

Healthy gingiva: facultative gram postitive
Periodontisis: gram negative
-A.a.
-Bacteroides
-Prevotella intermadia
Form biofilm
Release lipopolysaccharides, stimulate inflammation

34
Q

Chronic Periodontitis

A

Primary cause of tooth loss in pts >35 yo
No inflammation
Blunting and apical positioning of the gingival margins
Loss of attachment (shown with probe)

35
Q

Necrotizing Ulcerative Periodontitis

A

Similar to NUG, with loss of attachment and alveolar bone
May occur in preexisting areas of NUG or periodontitis
Pts are younger

36
Q

Periodontal Abcess

A

Occurs in pre-existing periodontal lesion
Can result from super infection
Appears as lateral enlargement of gingiva
May be red with edema or bleeding
Pain, sensitivity on palpation, foul taste, fever

37
Q

Pericoronitis

A

Develops around impacted or partially erupted teeth with debris between the gingival flap and the crown
Inflammation
Foul taste
Can’t close jaws, pain may radiate to throat, floor of mouth, or ear

38
Q

Periodontitis Histology

A

Hyperplasia of epithelium
Increased vascularity
Inflammation
