Histology

Question 1

Describe a pyogenic granuloma

Answer 1

• It is a tumour like growth of theoralcavity, frequently located surrounding the anterior teeth or skin that is considered to be neoplastic in nature. Non- cancerous
• Not associated with pus and does not represent a granuloma histologically
• Very vascular = bleeds easily
• Scattered inflammatory cells
• Gingiva is affected more than the alveolar part

Question 2

Describe a fibrous cell epulis

Answer 2

• Appears in the interdental papilla as a result of local irritation
• Fibrous epulis usually presents as a firm, pink, uninflamed mass
• More fibrotic in nature, few blood vessels, doesn’t bleed easily

Question 3

Describe a giant cell epulis

Answer 3

• Overgrowth of tissue due to irritation or trauma
• May be osteogenic in nature: bone growth due to calcified fibrosis
• Appears microscopicallyas a large number of multinucleated giant cells, which can have up to dozens of nuclei

Question 4

Describe a congenital granular cell epulis

Answer 4

• Masses that occur on the alveolar ridges of newborns
• Microscopically; hypervascularity, large granular cells with significant eosinophilic cytoplasm, and small basophilic nuclei

Question 5

Describe a heredity gingival fibromatosis

Answer 5

• Nonhemorrhagic, fibrous enlargement of keratinized gingiva
• Almost covers entire tooth crown
• It presents an autosomal dominant inheritance
• Great amount of fibroblasts causing collagen and fibronectin synthesis

Question 6

Describe a chronic hyperplastic gingivitis

Answer 6

• An overgrowth of gum tissue around the teeth
• Often a symptom of poor oral hygiene or a side effect of using certain medications
• Antiseizure drugs and immunosuppressants can be causes

Question 7

Describe an acute necrotising gingivitis

Answer 7

• Trench mouth is a severe gum infection caused by a buildup of bacteria in the mouth
• It’s characterized by painful, bleeding gums and ulcers in the gums
