What is the treatment for a fibroma?
Surgical excision
If you took a sagittal section of a fibroma what would its shape be?
It would look like a tree (as a 3 year old would draw one) with a narrow trunk at the base (peduncalated) and a larger circular globed structure on top

Pink, White, or Grey
What is the male to female ratio for irritation fibromas
1:2
What causes the leaf shaped “flat” variant of the irritation fibroma?
It is flat because it develops underneath a denture….tissue goes back to normal after excision

What causes a Giant Cell Granuloma?
Trauma to the alveolus
What is the histology of the Giant Cell Carcinoma
Multinucleated cells with a vascular background
What is the treatment of for a Giant Cell Carcinoma
Excision down to bone + Scale and RP
In some cases, this lesion can be describes as a maturing pyogenic or giant cell granuloma with dystrophic calcifications

What is the histology of a Peripheral Ossifying Fibroma?
Bone within fibrous CT
What is the cellular cause of a Focal Inflammatory Fibrous Hyperplasia
An increase of fibrocytes and collagen production in response to irritation
What are Fordyce’s Granules
Ectopic sebaceous glands
What % of the population has Fordyce’s Granules

What is the visual description of Fordyce’s Granules?
Yellowish White Papules
Where are the two most likely locations to develop Fordyce’s Granules?
Buccal Mucose > Lips
What is the treatment for Fordyce’s Granules?
There is no treatment
When do Fordyce’s Granules start?
In childhood and they stick around through adulthood
How could you describe the number 6 most common lesion….Hemangioma?
A benign proliferation of blood vessels
What percent of kids have a hemangioma?
10-12%
How can palpating the lesion help diagnose a hemangioma?
It blanches

20-25%
How are the lesions grouped (apthous ulcers)?
1-2 lesion
0.5-1.0 cm in diameter
What is the treatment for Recurrent Aphthous Ulcerations
Steroids + Antibiotics
How would you describe the tissue of a recurrent aphthous ulceration?
Non-keratinized
Non-bound Mucosa
What causes recurrent aphthous ulcerations?
Unknown???
What is the key to diagnosing Recurring Aphthous Ulcerations
Location + Size + Number of Lesions
What are 3 complications of RAU?
