Q

Impact of 2018 periodontal disease classification

what is the reasons highlighted for the change in 2018:

A
  1. Differentiation between gingival and periodontal abscesses can be confusing.
  2. Abscess by definition is an acute lesion – hence chronic and acute terminology removed
  3. No peri-coronal abscess terminology

Q

FEATURES OF PERIODONTAL ABSCESS - RADIOGRAPHIC

A

Radiographic

Cannot see a periodontal abscess on a radiograph!

Supporting evidence of periodontal involvement:
- Bone loss
- Furcation may be involved if molar tooth

22
Q

Signs and symptoms depend on stage of development of abscess

What will diagnosis be based upon?

A

Clinical examination findings
special tests results:
- Radiographic examination
- Pulp vitality tests

23
Q

What does management depend on?

A
  • Stage of development of abscess
  • Overall prognosis of tooth
  • Patient’s medical history/ compliance and motivation
24
Q

Management of acute periodontal abscess

May be an unplanned “emergency” and may interrupt treatment plan

What will this require?

A

Control of infection
Relief from pain
Assessment of prognosis/need for further therapy

25
Q

what are the Proposed 4 therapeutic alternatives ?

A
  • Incision and drainage and debridement of the abscess
  • Tooth extraction
  • Antimicrobials ?
  • Surgery
26
Q

describe the MANAGEMENT OF PERIODONTAL ABSCESS WITH PUS NOT DRAINING (1)

A
  • Check no impacted material in pocket
  • Relieving occlusion is advocated
    - Although affected tooth may be slightly extruded, may be more comfortable to grind opposing tooth? Keep in mind not to be aggressive with this.
  • Advise hot salt mouthwashes to encourage drainage
    - 1/2 teaspoon salt in cup of hot water
    - rinse for 1 min; repeat until cup empty
    - repeat several times daily for 2-3 days
27
Q

describe the MANAGEMENT OF PERIODONTAL ABSCESS WITH PUS NOT DRAINING (2)

A

Advise pain killers
e.g. ibuprofen (2 x 200mg three to four times daily) or paracetamol (2 x 500mg every 4-6 hours)

 If not possible to achieve drainage and severe pain is present and risk of spread of infection:
- Systemic antibiotic may be prescribed, for example: (refer SDCEP guidelines and BNF)
- Preferred first line of antibiotic - Phenoxymethyl penicillin 500mg 4 times a day – due to narrow spectrum
- Metronidazole 400mg three times per day for 5 days.

 Review patient after a few days

28
Q

What is included in the review stage?

A

Review signs and symptoms

After acute phase, assess prognosis
- Is it a recurrent abscess?
- Is further periodontal therapy indicated?
- Is extraction indicated?

29
Q

describe the MANAGEMENT OF PERIODONTAL ABSCESS WITH PUS TO DRAIN

A

Achieve drainage
- Local gentle debridement in the pocket
- Remove any impacted material
- Incision and drainage if indicated

Advise hot salt mouthwashes
Relieve occlusion
Advise pain killers as appropriate
Review in a few days

30
Q

describe the PERIODONTAL ABSCESS WITH SYSTEMIC INVOLVEMENT

A

Occasionally see evidence of associated systemic involvement:

Extraoral swelling
Lymphadenopathy
Rarely cellulitis
Malaise
Raised temperature

31
Q

MANAGEMENT OF PERIODONTAL ABSCESS WITH SYSTEMIC INVOLVEMENT

A

Acute phase as for abscess with pus to drain, plus:
- Incision and drainage if appropriate
- Systemic antibiotics (consider if severe systemic involvement or immunocompromised situations such as uncontrolled diabetic)
- Antibiotic sensitivity ideal
- Phenoxymethyl penicillin q.i.d for 5 days (recent update – June 2021 SDCEP), amoxicillin if patient is not compliant
- eg Metronidazole 400 mg t.i.d. 5 days

  - Re evaluation after 24 to 48 hours.
32
Q

What do we need to consider in a differential diagnosis?

A

Need to consider relevant findings from history, examination, signs, symptoms, results of special tests

33
Q

For periodontal abscess, what may differential diagnosis include?

A
  • Gingival abscess – not anymore as per the new classification 2018
  • Pericoronal abscess - not anymore as per the new classification 2018
  • Periodontic-endodontic lesion
  • Periapical abscess
34
Q

describe a gingival abcess

A
  • Localised purulent infection that involves the marginal or interdental papilla
  • Localised, painful, rapidly expanding
    - Acute inflammatory response to foreign agents
  • Red, shiny, smooth
  • Fluctuant within 24 – 48 hours
  • Points and discharges spontaneously
35
Q

describe pericoronal abscess

A

Localised purulent infection within tissue surrounding crown of partially erupted tooth
- Mandibular third molar common site
- Red and swollen gingival flap
- Infection may spread
- Possible systemic involvement

36
Q

PERIODONTAL-ENDODONTIC LESIONS

what may be aetiology be?

A

Primary periodontal, secondary endodontic
- ie necrotic pulp as consequence of periodontal involvement
Often, poor/hopeless prognosis

Primary endodontic, secondary periodontic
- ie periodontium is involved after pulpal necrosis

37
Q

describe periapical abcess

A

Pulpal necrosis eg carious pulpal involvement on heavily restored tooth

Non-vital (confirm with pulp test)

Periapical tissues involved (periapical periodontitis)

Periodontal tissue involvement NOT a key feature

Tooth Tender To Percussion (TTP), may be acutely painful

38
Q

NECROTISING PERIODONTAL DISEASES (1999 classification)

A
  • Necrotising ulcerative gingivitis (NUG) and
  • Necrotising ulcerative periodontitis (NUP)
    be collectively called “Necrotising periodontal
    diseases” as may be different stages of same infection
39
Q

describe specific features of NECROTISING PERIODONTAL DISEASES (NPD)

A
  • painful, interdental necrosis, bleeding gingivae
  • necrotic ulcers affecting interdental papillae
  • “punched out” appearance
  • ulcers painful, covered by grey slough
  • gingival bleeding with little provocation
  • possible halitosis, “foetor oris”
  • possible lymph nodes – involvement
  • NB there is not a “chronic” form of NPD – can recur tho’
40
Q

AETIOLOGY OF NPD (NECROTISING PERIODONTAL DISEASES)

A

Fusiform-spirochaete bacterial infection
- Selenomonas sp., Fusobacteria sp., P. intermedia
- spirochaetes, Treponema sp

4 zones in gingival lesion
Bacterial zone
- Neutrophil rich zone
- Necrotic zone
- Spirochaetal infiltration zone

41
Q

list the NPD PREDISPOSING FACTORS

A

Stress
Immune suppression (may be feature of HIV infection)
Smoking
Poor diet or malnutrition
Pre-existing gingivitis, poor oral hygiene, previous history of NPD

42
Q

MANAGEMENT NPD - local measures

A
  • remove gross deposits plaque and calculus
  • ultrasonic scaler useful
  • oxidising mouthwash (hydrogen peroxide; Bocasan)
  • gentle oral hygiene + 0.2% chlorhexidine rinse to aid plaque control, help prevent secondary infection
43
Q

MANAGEMENT NPD - systemic measures

A

metronidazole 200 (or 250 mg) t.i.d. for 3 days

44
Q

MANAGEMENT NPD - after “acute” phase

A

Periodontal therapy
- OHI
- Scale and polish/ root surface debridement
- Advise stop smoking
- Other predisposing factors eg stress management

Some minor regeneration of papillae possible

45
Q

RECURRENCE / PROGRESSION OF NPD

A

NPD:
- May become “recurrent”

Necrotising periodontitis:
- May involve the necrosis of gingival tissues, periodontal ligament, alveolar bone

Necrotising stomatitis:
- Necrotising process below / apical to mucogingival junction

46
Q

describe PRIMARY HERPETIC GINGIVOSTOMATITIS

A
  • Caused by herpes simplex virus type 1.
  • Primary contact
  • Essentially disease of childhood
  • Becoming more common in older ages
  • Immunity to virus develops
  • Lowered resistance may lead to herpes labialis - “cold sore” (30% population)
47
Q

describe the DIAGNOSIS OF PRIMARY HERPETIC GINGIVOSTOMATITIS (1)

A

Acute onset
Fever
Malaise
Cervical lymphadenopathy
Gingivae very acutely inflamed
- very red
- swollen

Vesicles:
- painful, any part of oral mucosa
- often hard palate, dorsum tongue, gingiva
- 2-3mm, dome shaped
- rupture leaves circular shallow ulcers with yellowish or grey floors and red margins
- smears show ballooning degeneration of viral damaged cells

Rising titre of antibodies to virus

48
Q

describe the MANAGEMENT OF PRIMARY HERPETIC GINGIVOSTOMATITIS as a viral infection

A
  • It will run its course in 7-18 days
  • Antibiotics are NOT indicated! it is viral infection!
  • Anti-viral therapy acyclovir would need to be used early to be effective
49
Q

describe the MANAGEMENT OF PRIMARY HERPETIC GINGIVOSTOMATITIS

supportive treatment

A

Soft diet and plenty of fluids
Analgesics for control of pain and fever
Bed rest if necessary
Chlorhexidine rinse/gentle swab can
- relieve soreness
- control secondary infection
- may hasten healing

50
Q

CAUTION: PRIMARY HERPETIC GINGIVOSTOMATITIS

A

Very infectious, via close contact
Transmissable via saliva
Caution when treating patients with virus - infection from vesicle or saliva:
potential for painful “herpetic whitlow” of digit
vesicles and crusting resemble herpes labialis
