According to Jones and Franklin, what percentage of specimens from oral and max pathology were for children under 16?

10%

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

Which lesions were rare?

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?

Radicular cyst
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

29

T/F MNE are rapidly growing?

T
