1
What percentage of lesions were benign and what percentage were malignant?
Majority of lesions were benign
Less the 1% malignant
2
Which lesions predominate?
AOT
Ameoloblastic fibroma
3

Odontogenic tumours
4
What were the most frequently diagnosed mucosa lesions?
Mucous extravasion cyst 16%
5
How frequent were tooth pathology, salivary gland disease and mucosal path?
Tooth: 22%
Salivary gland: 19%
Mucosal: 12%
6
What percentage of Periapical path was seen and what type of lesions were they?nand how frequent were they?

Residual cyst
Chronic apical gran
13% of cases
7
Now can you classify lesions?
Newborn
Infective/ulcerative
Pigmented, vascular and red lesions
Exophytic
Gingival enlargement
8
Which newborn pathology is there?
Gingival cysts of infancy which include:
1. Bohns nodules
2. Gingival cyst of newborn
3. Epstein pearl
Rare:
congenital epulis of newborn
Melanotic nueroectoderma, tumour of infancy
Other
Partial ankyloglossa
9
How do gingival cysts appear?
Small
White
Grey lesions on mucosa, alveolar ridge and hard palate
10
How common are gingival cysts of newborn?
75% of new borns
11
Why may parents not know their babies have gingival cysts?
Asymmptomic and rupture witching first three months of life
12
What is the name of the gingival cyst that occurs on the alveolar ridge?
Bohns nodules
13
Where do Bohns nodules arise from?
They arise from the remanants of the dental lamina
14
What is the dental lamina?
It is the earliest epithelium to grow into ectomesenchyme
15
What are the remnants of dental lamina called?
Epithelial cell rests of serres
16
Where are the epithelial cell rests of serres located?
In the CT between the developing tooth crowns and oral mucosa
17
What can happen to the Bohns nodules?
Can undergo cystic degen
18
What are the midline raphe cysts called?
Epstein pearls
19
How do Epstein pearls develop?
Small lesions located along the Palatal midline and they develop from trapped epithelium in the Palatal raphe which then undergo cystic change
20
What are Epstein pearls lined by?
Keratinising stratified squamous epithelium
21
Wheee do you find a congenital epulis?
Rare lesion seen in neonates
Usually in the anterior maxilla along the alveolar ridge
22
What is the clinical appearance of a congenital epulis?
Soft round exophytic swelling
23
In which gender a congenital epulis err common amongst?
Females
80% seen in females
24
What is inside congenital epulis?
Granular cells which are covered by epithelium
25
How do you manage congenital epulis?
Benign
Excise
26
When does a melanocytic tumour develop??
This develops withing the first few mths of life.
60% are found in those less than 6 months
27
Where are the majority of the MNT?
70% anterior maxilla
28
What is the composition of a MNE?
Epithelial cells containing melanin with a fibrous stroma
Neoplasm of neuroblsstic pigmented epithelial cells of neural crest origin
