DEOH201 Mesenchymal lesions

Fibrous epulis clinical appearance

presents as an isolated, small, firm polypoid lump in the mouth and is painless and slow growing.

Fibroma pathogenesis

Develop on response to chronic trauma such as overhanging restorations, calculus, etc. The lesion represents a proliferation of fibrous connective tissue in response to stimuli.

Variants of fibroma

denture-induced hyperplasia and irritative hyperplasia.

Fibroma behaviour

Non-aggressive, does not bleed spontaneously, and may enlarge gradually if irritation persists.

Fibroma Prognosis

Good as recurrence is rare if the causative factor is removed.

What is a pyogenic granuloma?

A non-neoplastic inflammatory lesion most commonly arises in the labial aspect of the gum, especially interdental papilla. It is a form of reactive hyperplasia comprised of granulation tissue.

Pyogenic granuloma pathogenesis

It results from an exaggerated tissue response to chronic irritation, trauma or poor oral hygiene. It may turn into a fibrous lesion over time.

Pyogenic granuloma and pregnancy

Hormonal changes, such as those during pregnancy, can lead to a subtype called pregnancy epulis.

Pyogenic granuloma behaviour

Rapid enlargement, may ulcerate if traumatised, can recur if irritants are not removed and does not invade bone or deeper tissues.

Pyogenic granuloma prognosis

Good with the complete removal of irritants, however, recurrence is possible if causal factors persist.
