What is the most severe NPD seen in kids due to severe malnutrition?

A

Noma (don’t look it up, trust me its terrible)

  3. Antibiotics (only if needed, not for pain)
26
Q

What are some further treatment options beyond the acute therapies?

A
  1. Further medical therapy
  2. Surgical therapy (defect elimination)
  3. Predisposing factor elimination
27
Q

Define GINGIVAL abscess

A
  • Localized, painful, rapidly expanding lesion in vital tissue
  • Usually of sudden onset
  • Generally limited to the marginal gingiva or interdental papillae (sulcus)
28
Q

What is the usual etiology (cause) of gingival abscesses?

A

Irritation from foreign bodies forcefully embedded into previously healthy tissues

29
Q

Define PERIODONTAL abscess

A
  • Localized, purulent inflammation in the periodontal tissues
  • Acute or chronic,
  • Vital pulp
  • Extension from pocket to perio tissues (not restricted to gingiva)
30
Q

Where does a periodontal abscess tend to localize upon extension from the pocket to periodontal tissues?

A

Along the lateral root surfaces

31
Q

When does localization of a periodontal abscess tend to occur?

A

Localization occurs when drainage through the pocket is impaired

32
Q

What is a common reason for impaired drainage leading to periodontal abscess?

A

Post-treatment shrinkage of tissue over incompletely removed calculus

33
Q

What 2 events/procedures often are followed by a periodontal abscess?

A
  1. Trauma (root fracture)

2. Endodontic perforation

34
Q

What are the 3 types of periodontitis-related abscesses?

A
  1. Exacerbation of chronic lesion
  2. Post-therapy abscess
  3. Post-antibiotic abscess
35
Q

When and to whom does a periodontitis-related abscess due to exacerbation of a chronic lesion occur?

A
  • Occurs when chronic lesion becomes acute

- Seen in untreated patients and maintenance patients (recurrent infection)

36
Q

When does a periodontitis-related Post-therapy abscess usually occur?

A
  1. Following SRP (calculus)

2. Following surgical therapy (calculus, foreign bodies)

37
Q

Why might someone end up with a periodontitis-related post-antibiotic abscess?

A
  • Taking antibiotics for OTHER reasons
  • 40% get abscess within 4 weeks
  • B/c MUST have mechanical debridement with antibiotics or get SUPER-INFECTION!!!!!
38
Q

What are the 2 non-periodontitis-related abscesses?

A
  1. Foreign body impaction

2. Root morphology alterations

39
Q

What are 2 common causes of non-periodontitis-related Foreign Body Impaction Abscesses?

A
  1. Oral Hygiene devices

2. Food Particles

40
Q

What are 3 common causes of non-periodontitis-related Root morphology alteration abscesses?

A
  1. External root resorption
  2. Cemental (root) tears
  3. Iatrogenic (endodontic perforation)
41
Q

What percent of periodontal abscesses are emergency conditions?

A

8-14%

How common are periodontal abscesses among patients treated for periodontitis?

A

27%

43
Q

How common are periodontal abscesses in untreated patients with periodontitis?

A

> 50%

44
Q

What is the most prevalent site for periodontal abscesses (which tooth) and why?

A

Molars, due to anatomical features such as multiple roots

45
Q

What 2 bacteria tend to be found in periodontal abscesses?

A
  1. Periodontitis flora

2. P. gingivalis

46
Q

What type of obstruction tends to prevent drainage and leads to abscess

A

Mechanical obstruction

47
Q

What are the 4 MOST IMPORTANT features to look for when diagnosing as a periodontal abscess?

  3. Suppuration
  4. Pain
48
Q

A
  1. Swelling
  2. Redness
  3. Suppuration (spontaneous or elicited)
  4. Pain
  5. Gingival tenderness
  6. Assoc. with deep pocket
  7. BOP
  8. mobility
  9. Radiographic bone loss
  10. Fever
  11. Malaise
  12. Lymphadenopathy
49
Q

How does a periodontal abscess differ from a periapical abscess!!! KNOW! LIKELY TQ!

A

Peri-apical abscess = DEAD TOOTH

Periodontal abscess = tooth is usually vital

50
Q

What are 2 important complications resulting from periodontal abscesses?

A
  1. Tooth loss

2. Systemic infection

51
Q

What are the 2 mechanisms by which a periodontal abscess may become a systemic infection (travels to brain, blood, and/or vital organs)?

A
  1. Dissemination thru tissues DURING THERAPY

2. Dissemination thru bacteremia (untreated abscess) – upon brushing or chewing

52
Q

What is the #1 site in the mouth for metastatic tumors? TQ!!

A

Gingiva – must biopsy if does not respond to tx within 2 weeks

53
Q

What other diseases must you eliminate via differential diagnosis for a periodontal lesion?

A
  1. Periapical (endodontic) abscess
  2. Vertical root fractures
  3. Endo-perio abscess
  4. Osteomyelitis
  5. Tumor
54
Q

Describe therapy prescribed for periodontal abscesses

A
  1. Acute lesion management:
    • incision and drainage
    • SRP
    • Antibiotics
    • Periodontal surgery
  2. Treatment of original/residual lesion
55
Q

When should you include antibiotics in acute treatment of a periodontal abscess?

A

If there is systemic involvement

56
Q

When should you include periodontal surgery in acute treatment of a periodontal abscess?
