The epithelial lining of radicular cysts may be derived from:

cell rests of
epithelium of the
Oral epithelium from a f tract

What are some sequelae of chronic apical periodontitis?

1

What are some developmental odontogenic cysts?

1

What are some inflammatory odontogenic cysts?

Reduced enamel epithelium gives rise to...

1

Epithelial cell rests of serres give rise to odontogenic keratocysts and eruption cysts

1

Reduced enamel epithelium gives rise to eruption cyst, paradental cyst and dentigerous cyst

1

Epithelial cell rests of malassez are the source of all radicular cysts

Pocket radicular cysts are

True radicular cysts are

1

The cyst cavity of a radicular cyst develops from death of the cells and necrosis of the tissue.

Clinical features of radicular cysts:

Majority are

Histological features of radicular cysts:

epithelial lining
crystals
Plasma cell and infiltration
bodies
Epithelial mucus

Contents of a radicular cyst:

proteins

1

What type of molecule breaks down bone matrix to make room for cyst expansion?

1

A radicular cysts lumen is when compared to the inflammatory exudate. This means breakdown products in the inflammatory exudate travel into the which draws more water in, leading to further .

1

Which molecules are important in bone resorption

1

Features of residual cysts are:

connective tissue
Retained after
epithelium

1

Condensing osteitis leads to dense s bone being deposited around the root apex due to low grade .

Radiographic features include radio mass surrounding the of the root(s). The periodontal ligament is also .

Histological features include dense bony t with little marrow tissue.

In periapical cemental d -osseous tissue replaces bone. It most commonly occurs in the anterior .

The three stages of periapical cemental dysplasia are:

Osteo
Cemento
M

1

Acute alveolar abscess is a process following on from periapical periodontitis. It causes initial t of the tooth which goes on to become extremely painful.

Radiographic features including slight of the periodontal ligament space

Histological features include:
Disintegrating s
C debris
N material
Bacterial c
