Q

Why are dentures, particularly ill-fitting dentures, associated with a heterogenous group of oral mucosal lesions? Give three reasons.

A
  1. Acute or chronic reactions to microbial denture plaque
  2. A reaction to constituents of denture base materials
  3. Mechanical denture injury
17
Q

List 7 pathological changes related to denture wear in the mouth.

A
  1. Ulcers
  2. Denture stomatitis
  3. Angular chelitis
  4. Denture irritation hyperplasia
  5. Flabby ridges
  6. MRONJ/osteoradionecrosis
  7. Allergic reactions
18
Q

What ulcer would indicate a need for urgent referral pathway?

A
  • non-healing desire adjustments to denture
  • obviously suspicious lesion
  • persist for >3 weeks
19
Q

What is the clinical appearance of denture stomatitis?

A

Oedema and erythema

20
Q

What is the management for denture stomatitis?

A
  1. Advise patient to take denture out at night
  2. Advise patient to clean denture with a. Soft brush
  3. Possible use of Chlorohexidine mouthwash
  4. Use of nystatin or other appropriate antifungal
  5. New denture
21
Q

What condition often co-exist with denture Stomatitis?

A

Angular cheilitis

22
Q

What is often the cause of angular cheilitis?

A

Overclosure, loss of OVD/excessive FWS. Normally due to old worn dentures.

23
Q

What is the treatment for angular cheilitis?

A

Miconazole

24
Q

What is the initial management for denture induced hyperplasia?

A
  1. Major ease of denture
  2. Tissue conditioner
  3. Review and repeat if required
  4. New denture
25
Q

When does a flabby ridge most often occur?

A

When lower anterior only present and no lower denture, trauma to anterior upper ridge.

26
Q

What processes cause a flabby ridge?

A

Bone resorption and fibrous replacement resorption.

27
Q

What is the management of a flabby ridge?

A

New denture covering whole denture bearing area with good peripheral seal AND opposing arch denture giving posterior support.

28
Q

Why might you have to be careful making dentures for a patient with who has received radiotherapy or is taking bisphosphonates?

A

An ill fitting denture in a patient on anti-resorptive medication can be a factor in MRONJ or ORN

29
Q

What condition do allergic reactions to dentures often mimic?

A

Denture stomatitis

30
Q

Allergic reactions to dentures are uncommon. What are the usual culprits?

A

Nickel contains CO/CR
OR
PMMA (especially self-cure relines as higher monomer content)
