1. HYPERPLASIAAND
RELATED DISORDER
RELATED TO ORAL
MUCOSA

2. hyperplasia
Localized hyperplastic lesion of the oral mucosa:
 Epulides;
A) fibrous epulis
B) pregnancy epulis
C) peipheral giant cell granuloma
 Pyogenic granuloma
 Fibroepithelial polyp
 Denture irritation hyperplasia
 Papillary hyperplasia of the palate

3. Epulides
 Common, localized tumour-like gingival enlargment.
 Mostly arise from interdental tissue.
 Trauma & chronic irritation (e.g subgingival plaque) are
the main aetiological factors.
 F > M
 80% occur anterior to molar teeth.
 Maxilla > Mandible.

4. A) Fibrous epulis
• Most common, present as pedunculated mass, firm of
consistency, with similar colour to adjacent gingiva.
• Mostly arise btween 11 – 40 years of age.

5. B) Pregnancy epulis “vascular epulides”
• Present as soft, deep reddish-purple swelling, extensively
ulcerated.
• Haemorrhage occur spontaneously or in minor trauma.
• Arise any time of pregnancy with onset usually around the
end of the first trimester.
• After delivery may regress spontaneously.

6. C) Peripheral giant cell granuloma
• Least common.
• Present as pedunculated drak-
red in colour commonly ulcerated.
• Peak incidence in males is the 2nd
decade, while in female is the 5th
decade.
• Arise anywhere on gingival or
alveolar mucosa.
• Mandible > Maxilla.

7. Pyogenic granuloma
 Arise on gingiva, tongue,
buccal and labial mucosa.
 Initiated by trauma or irritation.
 Hyperplastic granulation
tissue.
 treatment include; Excision to
periosteum or periodontal
membrane.
 May be recur but no malignant
potential.

8. Fibroepithelial polyp
 Arise manily in cheeks ( along the occlusal line), lips,
tongue.
 Present as firm, pink, painless swellling from few
millimeters to centimeters in diameter.
Leaf fibroma: a fibroepithelial polyp occurs in the palate
under denture, occaionally the surface is whitish due to
frictional keratosis.

9. Denture irritation hyperplasia
 Related to the periphery of an ill
fitting denture.
 Single or multiple.
 Present as firm leaf-like folds of
tissue embracing the over
extending flange of denture.
 Arise in the depth of vestibular
and lingual sulci but may
involve the inner surface of lips,
cheeks, palate ( along posterior
edge of upper denture).
 More in the lower denture.
 F > M

10. Papillary hyperplasia of palate
 Aetiology not fully
understood, on the other
hand; poor denture
hygiene / trauma related to
rocking of ill fitting denture
/ sleping with dentures /
candida associated
denture stomatitis paly a
significant role.
 Present clinically as
numerous, small, tightly
packed papillary
projections over part or all
denture bearing area.
