Chronic apical gran
13% of cases
Now can you classify lesions?
Pigmented, vascular and red lesions
Which newborn pathology is there?
Gingival cysts of infancy which include:
1. Bohns nodules
2. Gingival cyst of newborn
3. Epstein pearl
congenital epulis of newborn
Melanotic nueroectoderma, tumour of infancy
How do gingival cysts appear?
Grey lesions on mucosa, alveolar ridge and hard palate
How common are gingival cysts of newborn?
75% of new borns
Why may parents not know their babies have gingival cysts?
Asymmptomic and rupture witching first three months of life
What is the name of the gingival cyst that occurs on the alveolar ridge?
Where do Bohns nodules arise from?
They arise from the remanants of the dental lamina
What is the dental lamina?
It is the earliest epithelium to grow into ectomesenchyme
What are the remnants of dental lamina called?
Epithelial cell rests of serres
Where are the epithelial cell rests of serres located?
In the CT between the developing tooth crowns and oral mucosa
What can happen to the Bohns nodules?
Can undergo cystic degen
What are the midline raphe cysts called?
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
What are Epstein pearls lined by?
Keratinising stratified squamous epithelium
Wheee do you find a congenital epulis?
Rare lesion seen in neonates
Usually in the anterior maxilla along the alveolar ridge
What is the clinical appearance of a congenital epulis?
Soft round exophytic swelling
In which gender a congenital epulis err common amongst?
80% seen in females
What is inside congenital epulis?
Granular cells which are covered by epithelium
How do you manage congenital epulis?
When does a melanocytic tumour develop??
This develops withing the first few mths of life.
60% are found in those less than 6 months
Where are the majority of the MNT?
70% anterior maxilla
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
