Almost exclusively male predilection

Question 22

Posterior Lingual Mandibular
Salivary Gland Depression

All Mandible Slightly higher in females but No predominant gender No treatment

Question 26

Residual/Recurrent Cyst Pathophysiology (2)

Answer 26

Results from incomplete removal or residual viable epithelial cystic lining following treatment of a cyst Previous history of periapical disease

Question 27

Residual Cyst Clinical (2)

Answer 27

Asymptomatic, normally found on radiographic examinations of edentulous areas Tooth or root may or may not be present

Question 28

Residual Cyst Radiographic (3)

Answer 28

* Well defined radiolucency with smooth, round, corticated borders * Usually 5mm or less in diameter * May not be any root present if tooth was previously extracted

Question 29

Residual Cyst Age Site Gender (Sex)

Answer 29

Middle age or older More common in maxilla More common in males

Question 30

Residual/Recurrent Cyst Management (same as PA cyst) (2)

Answer 30

Requires removal of the cyst lining Enucleation if a large cyst

Question 31

Fibrous Healing Defect (Apical Scar) Pathophysiology (3)

Answer 31

* Develops after inflammation that affects the integrity of the periosteum * Once disease is eradicated, the bone heals without a mineralized bony matrix * Due to the loss of the periosteum, only fibrous connective tissue fills the site of the previous disease

Question 32

Fibrous Healing Defect (Apical Scar) Clinical (2)

Answer 32

* Asymptomatic * Noted in areas with a previous history of disease or trauma

Question 33

Fibrous Healing Defect (Apical Scar) Radiographic (3)

Answer 33

* Well circumscribed radiolucent lesion at site of previous surgery * “punched out” or “see through” appearance * May resemble residual cysts in edentulous areas but lack cortication

Question 34

Fibrous Healing Defect (Apical Scar) Management (2)

Answer 34

No treatment indicated A previous history of disease is critical in establishing the diagnosis

Question 35

Answer 35

* Expansion, pain, or paresthesia * Symptoms include complaints of burning, tingling, and aching sensations

Question 36

Neuroma, Neurofibroma Radiographic (2)

Answer 36

* Well circumscribed radiolucency of various shapes * In the mandible it usually forms in the mandibular canal

Question 37
