1

Gingivitis

Inflammation limited to the soft tissues that surround teeth

2

Gingivitis Clinical Features

Accumulation of dental plaque and calculusInflammation can be local or generalizedDiffuse, marginal gingivitis, or papillary gingivitis

3

Gingivitis Signs

Loss of stippling and bleeding on gentle probingErythematous gingiva Severe cases may have pyogenic granulomas

4

Gingivitis Epidemiology

Increased susceptibility during pubertyProgesterone (pregnancy) increases permeability of gingival blood vesselsRisk factors: smoking, stress, poor diet

5

Gingivitis Histology

Inflammatory infiltrate with PMN, then lymphocytes

6

Gingivitis Treatment

Reduce know risk factorsImprove oral hygieneRemove plaque

7

Necrotizing Ulcerative Gingivitis

Vincent Infection, Trench MouthInfection caused byspirochetes and bacillus fusiformis in the presence of psychological stress.

8

NUG Clinical Features

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

9

NUG Epidemiology

Mostly seen in young and middle-aged adults and militaryCan occur in all ages

10

NUG Histology

Non-specificInflammation, ulceration, necrotic material

11

NUG Treatment

Debride and rinses to remove bacteriaResolves quickly

12

Granulomatous Gingivitis

Unexplained granulomatous inflammation on gingival biopsyRule out all other possible causesMay be caused by foreign body in gingival tissue

13

Granulomatous Gingivitis Clinical Features

Red and white macules at interdental papillaePain, sensitivity

14

Granulomatous Gingivitis Epidemiology

Most frequently in adults

15

Granulomatous Gingivitis Histology

Granulomas with multinucleated giant cells

16

Granulomatous Gingivitis Treatment

Surgically excise foreign bodyIf no foreign body, evaluate for other diseases

17

Desquamative Gingivitis

Gingival epithelium that sloughs spontaneously or with minor manipulation

18

Desquamative Gingivitis Epidemiology

Female> 40 yo

19

Desquamative Gingivitis Clinical Features

Gradual involvementMore facial than lingualSmooth erythemaLoss of stipplingPainfulCan have blisters

20

Desquamative Gingivitis Histology

Lichen planus or pemphigoid

21

Desquamative Gingivitis Treatment

Clean areaDoxycyclineImmunosupressants

22

Drug Related Gingival Hyperplasia

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

23

DRGH Epidemiology

25 and younger

24

DRGH Clinical Features

Enlargements start in interdental papillae and spreadDark red, bleeds easily, can ulcerateCan interfere with speech and mastication

25

DRGH Histology

Elongated rete ridgesIncreased collagen

26

DRGH Treatment

Discontinue medicationIf med can't be stopped - professional evaluations and home plaque controlFolic Acid

27

Gingival Fibromatosis

Hyperplasia of gingiva

28

Gingival Fibromatosis Epidemiology

Familial or idiopathicBegins < 20 yoMay be associated with hypertrichosis, epilepsy, and mental retardation

29

Gingival Fibromatosis Clinical Features

Enlarged gingivaNormal colorSmooth surface

30

Gingival Fibromatosis Histopathology

Dense hypocellularHypovascular tissueAbsent inflammation
