progression of aggressive periodontitis

A
  • might burn out
  • might extend to more teeth
  • localized might become generalized
  • **observe unaffected siblings
  • susceptibility for progression/extension might be environmental (both types found in siblings) or if genetic, suggests varying degrees of penetrance for the genes

Q

periodontitis as manifestation of systemic diseases

A
  1. hematologic disorders: leukemia, neutropenias, etc
  2. immune system disorders: HIV, transplant patients
  3. genetic disorders: cyclic neutropenia, down syndrome (cause reduced immune system)

NOT METABOLIC DISEASES (diabetes, hormonal – you can have periodontitis as a complication of diabetes, but no ‘diabetes assoc. periodontitis’ like in gingivitis)

Q

NUG/NUP

A

NUP = NUG + attachment loss

NUG = necrotizing ulcerative gingivitis = acute infection of the gingiva which may have a combo of…

  • ulceration/ necrosis of gingival margins/papilla
  • necrotic gray pseudo- membrane
  • severe pain
  • bright red marginal gingiva
  • spontaneously bleeding gums
  • malodor
  • possible fever adn lymphadonopathy

22
Q

difference in NUG and NUP

A

in NUP, you lose attachment

***these are the ones they check for on college campuses around exam time – smoking, stress, lack of sleep

23
Q

NUG and NUP

A

treat with light scaling and chlorhexadine

rare and usually only in HIV+

localized or generalized

24
Q

clinical patterns of NUG/NUP (soft tissue destruction/necrosis of papillary and possibly marginal gingiva)

A
  • rare
  • localized or generalized
  • predisposing factors = stress, usually young adults, poor oral hygiene, smoking, poor nutrition

USUALLY HIV+

25
Q

histology of NUG and NUP

A
  • ulcerated epithelium
  • severe inflammation
  • areas of necrosis
  • FREQUENT PRESENCE OF SPIROCHETES
26
Q

NUP vs chronic perio

A

NUP can occur in a matter of weeks, very rapid loss

chronic – 1mm/6months is as fast as it gets

27
Q

clinical signs of NUP

A
  • NUG superimposed on previously existing or rapidly progressing perio lesions
  • might not be separate disease, might just be NUG combined with periodontitis at some sites
28
Q

gingival abscess

A
  • localized purulent infection that involves the marginal gingiva ir interdental papilla
  • clinical features = localized swelling in marginal or interdental gingiva with smooth red shiny surface; no attachment loss; pain; purulent exudate
29
Q

chronic vs acute (NUG, abscess)

A
  • chronic is slow, more manageable, comes and goes, patient might not even know they have it
  • acute is more painful adn exaggerated symptoms
  • NUG adn abscesses are more acute than chronic
30
Q

periodontal abscess

A

-localized purulent infection in tissues adjacent to periodontal pocket that may lead to destruction of PDL and alveolar bone

31
Q

periodontal abscess clinical features

A
  1. smooth, shiny swelling of gingiva
  2. pain, area tender to touch
  3. purulent exudate
  4. increased probing depth, NOT TO APEX
  5. tooth sensitive to percussion
  6. increased tooth mobility
  7. rapid loss of periodontal attachment
32
Q

when is periodontal abscess very likely

A

a few days after scaling in people with deep pockets. get top 4mm very clean, and they tighten up bc clean. so the pus from bottom part is trapped.

33
Q

combined perio-endo lesion

A
  • localized circumscribed area of infection involving both the perio and/or pulpal tissue.
  • infection can arise from pulpal inflammatory disease and express itself through the PDL or alveolar bone to oral cavity
  • or can arise from perio pocket communicating through accessory canals of tooth and/or apical communication and secondarily infect the pulp
  • can arise as sequela of fractured tooth
34
Q

endo lesion

A

periapical = chronic apical periodontitis

35
Q

clinical features of combined perio-endo lesion

A
  • sever perio attachment loss that often can be probed to apex of tooth
  • non responsive/ necrotic pulp
  • may have clinical appearance of perio abscess or endo abscess
  • signs may vary whether acute or chronic
  • smooth, shiny swelling of gingiva/mucosa
  • possible pain with area of swelling tender to touch
  • purulent exudate often noted
  • increased probing depth
  • tooth sensitive to percussion
  • increased tooth mobility
  • fistulous tract possible
  • rapid perio. att. loss
  • facial swelling, cellulitis possible
36
Q

does perio-endo lesion have to have fiistula

A

no. can drain through sulcus

37
Q

tooth related factors

A
  1. defective restorations
  2. anatomic (enamel pearl)
  3. fracture
38
Q

mucogingival deformaties

A
  • deviations from normal anatomic relationship between gingival margin and mucogingival junction
  • recession
  • probing beyond MGJ
  • loss of keratinized tissue
39
Q

mucogingival deformaties - gingival recession

A
  • relatively common, most often on facial surfaces
  • preexisting thin facial gingiva/bone
  • toothbrush abrasion, ortho, restorative
  • can be localized or generalized
  • periodontitis — you do have attachment loss but might not be periodontitis if overall healthy mouth with exact casue of recession known
40
Q

mucogingival deformaties - lack of keratinized gingiva

A
  • may occur in absence of disease

- generally narrowest on buccal of mandibular PMs

41
Q

common mucogingival conditions

A
  1. recession
  2. absence/reduction of keratinized gingiva
  3. probing depths beyond MGJ
    * *anatomic variations can complicate management – tooth position, frenulum inerstions, vestibular depth
42
Q

gingivitis on a reduced periodontium

A
  • resolution of periodontitis so prexisting attachment loss/bone loss possible
  • plaque at gingival margin
  • disease starts at gingival margin
  • change in gingival color and contour
  • increased gingival exudate
  • bleeding on provocation
  • inflammatory histo changes
  • reversible with plaque removal
43
Q

problems with ‘gingival health on reduced periodontium’ or ‘plaque induced gingivitis on reduced periodontium’

A
  • impossible to determine disease activity in single appt, so patient could have episodic periodontitis (whetehr or not there is bleeding)
  • if there is bleeding on probing, impossible to tell if it is gingivitis on reduced periodontium or active periodontitis
  • patients with thin periodontium may have active periodontitis that caises attachment loss and recession of gingiva, possibly ywithout deep pockets
44
Q

perio case types

A

I: gingivitis– inflammation of gingiva, no att.loss, hyperplasia/ edema/ shallow pocket (unless hyperplasia)
II: slight periodontitis– moderate pockets = 3-5mm; minor-moderate att loss = 1-2mm; no tooth mobility; satisfactory topography
III: moderate periodontitis– mod to deep pockets = 5-7mm; mod-severe att loss = 3-4mm; unsatisfactory topography; slight mobility
IV: severe periodontitis– deep pockets = 7+mm; severe att loss = 5+mm; advanced mobility, usually missiing teeth, may become prosthetic reconstruction cases

V = refractory — NOT USED– destructive periodontitis in patients who, when longitudnally monitored, demonstrate attachment loss at one or more sites despite well executed efforts to slow progression

45
Q

what are AAP case types used for?

A
  • initially to describe adult periodontitis for insurance companies
  • not used frequently now but still in use for disaes severity
46
Q

limitations of AAP case types

A
  1. not applicable to NUP, abscesses, aggressive periodontitis – really only for chronic periodontitis
  2. more easily applied to sextants than whole mouth bc it goes by worst area, and you could have localized severe and generalized slight
47
Q

difference between diagnosis adn AAP case type

A
  • diagnosis can be much more discriminating

- such as “localized severe with generalized moderate chronic perio” vs case type 4

48
Q

broad overview of case types

A 
I = gingivitis
II-IV = periodontitis
V = refractory perio, NOT USED
49

50
Q

AAP Case Type II

A

SLIGHT PERIODONTITIS: moderate pockets (3-5mm) and attachment loss of 1-2mm; minor-moderate bone/att loss; satisfactory topography; no tooth mobility

51
Q
