Q

What are the clinical features of OFG?

A

Lip swelling
Full thickness gingival swelling
Swelling of non labial facial tissues
Peri-oral erythema
Cobblestone appearance of the buccal mucosa
Linear oral ulceration
Mucosal tags
Lip/tongue fissuring
Angular cheilitis

18
Q

Which allergens are associated with OFG?

A

Cinnamon compounds
Benzoates
Much higher IgE mediated atopy rates

19
Q

How is OFG diagnosed?

A

Clinically - no lip biopsy needed

20
Q

What investigations can be used for OFG?

A

Measure growth
Full blood count
Haematinics
Patch testing
Diet diary to ID any triggers
Faecal Calprotectin
Endoscopy - risky in children
Serum Angiotensin Converting Enzyme

21
Q

How is OFG managed?

A

OH support
Symptomatic relief as per oral ulceration
Dietary exclusions
Manage nutritional deficiencies
Topical steroids
Topical tacrolimus
Short corses of oral steroids
Intralesional corticosteroids
Surgical intervention - if unresponsive long standing disfigurement

22
Q

Describe mucosal lesions of the tongue

A

Idiopathic and non-contagious
May be seen at a young age
Shiny red areas on the tongue with loss of filiform papillae are surrounded by white margins
Can cause discomfort with spicy food, tomato and citrus fruit/juice

23
Q

How are mucosal lesions of the tongue managed?

A

Bland diet during flare ups
Likely to become less troublesome with age

24
Q

Give examples of solid swellings

A

Fibroepithelial Polyp
Epulides
Congenital epulis
HPV-associated mucosal swellings
Neurofibromas

25
Q

Describe a fibroepithelial polyp

A

Common
Firm pink lump
Mainly in the cheeks, along occlusal line or tongue
Once established remains constant size
Thought to be initiated by minor trauma
Surgical excision is curative

26
Q

What are epulides?

A

Common solid swelling of the oral mucosa
Benign hyperplastic lesion
3 types:
- fibrous epulis
- pyogenic granuloma
- peripheral giant cell granuloma

27
Q

Describe a fibrous epulis

A

Pedunculated or sessile mass
Firm consistency
Similar colour to surrounding gingivae
Inflammatory cell infiltrate and fibrous tissue

28
Q

Describe a pyogenic granuloma

A

Soft, deep red/purple swelling
Often ulcerated
Haemorrhage spontaneously or with mild trauma
Probably a reaction to chronic trauma eg - calculus
Tend to recur after removal

29
Q

Describe a peripheral giant cell granuloma

A

Pedunculated or sessile swelling
Typically dark red and ulcerated
Usually interproximal with an hour glass shape
Radiographs may reveal superficial erosion of the interdental bone
May recur after surgical extraction

30
Q

Describe a congenital epulis

A

Rare lesion occurring in neonates
Most commonly affect the anterior maxilla
Affects females over males
Benign and simple excision is curative

31
Q

Give examples of HPV associated swellings

A

Verruca Vulgaris
Squamous cell papilloma

32
Q

Give examples of fluid swellings

A

Mucoceles
Ranula
Bohn’s nodules
Epsteins Pearls
Haemangiomas
Vesiculobullous lesions

33
Q

What is a mucocele?

A

A bluish, soft transparent cystic swelling affecting minor or major salivary glands
Most will rupture spontaneously

34
Q

When are mucoceles surgically excised?

A

Only if lesion fixed in size as will likely damage adjacent glands leading to recurrence
Involves removal of the cyst and the adjacent damaged minor salivary gland

35
Q

What is a ranula?

A

A mucocele in the floor of the mouth

36
Q

What are Bohn’s nodules?

A

Gingival cysts filled with keratin
Remnants of the dental lamina
Found in neonates and usually disappear in the early months of life

37
Q

What are Epstein Pearls?

A

Small cystic lesions found along the palatal midline
Thought to be trapped epithelium in the palatal raphe
Found in about 80% of neonates and disappear in the 1st few weeks

38
Q

What characterises TMJDS?

A

Pain
Masticatory muscle spasm
Limited jaw opening

39
Q

What questions should be asked in a history for TMJDS?

A

A description of the presenting symptoms
When did the discomfort begin?
Is the pain worse at any time during the day?
Exacerbating factors
Habits
Stress

40
Q

What should an extra oral examination for TMJDS include?

A

Palpation of the MoM both at rest and when teeth are clenched to assess tenderness and/or hypertrophy
Palpation of the TMJ at rest and when opening and closing to assess tenderness and click/crepitus
Assessment of opening - check for any deviation of the jaw and assess extent of opening

41
Q

What should an intra oral examination for TMJDS include?

A

Assessment of any dental wear facets
Signs of clenching/grinding - scalloped lateral tongue surface, buccal mucosa ridges

42
Q

How is TMJDS managed?

A

Explain the condition
Reduction of exacerbating factors
Allow the overworked muscles to rest
Symptomatic relief
If these measures are unsuccessful then refer for specialist care
