rare

33
Q

Salivary Gland Depression (stafne cyst)
clinical

A

Asymptomatic, usually found in routine
radiographic examinations

34
Q
A

stafne cyst

35
Q

Posterior Lingual Mandibular
Salivary Gland Depression
radio app

A

Well circumscribed posterior radiolucency in molar region between mandibular canal and inferior border

36
Q

Posterior Lingual Mandibular
Salivary Gland Depression

37
Q
A

Posterior Lingual Mandibular
Salivary Gland Depression

38
Q
A

stafne cyst on PA

39
Q

how could stafne cyst be confirmed

A

radio dye into whartons duct

40
Q

Posterior Lingual Mandibular
Salivary Gland Depression age, site, gender

Site: Between the mandibular canal and inferior border
Gender: Almost exclusively male predilection

41
Q

Posterior Lingual Mandibular
Salivary Gland Depression management

A

Positive diagnosis based on clincial and radiologic history negates the need for biopsy and histologic examination

42
Q

Focal Osteoporotic Bone
Marrow Defect of the Jaws clinical symptoms

A

asymptomatic

43
Q

Focal Osteoporotic Bone
Marrow Defect of the Jaws radio app

A
  • Unilocular, faint radiolucency
  • Not ragged but difficult to discern as a separate entity
  • loss of trabeculae
44
Q
A

focal osteoporotic bone defect

45
Q

Focal Osteoporotic Bone Marrow Defect of the Jaws age, site, gender?

Age: All
Site: Mandible
Gender (Sex): Slightly higher in females but No
predominant gender

46
Q

Focal Osteoporotic Bone
Marrow Defect of the Jaws management

A

no tx

47
Q

Residual/Recurrent Cyst
Pathophysiology

A

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

48
Q

Residual Cyst
Clinical

A

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

49
Q

residual cyst radio app

A
  • 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
50
Q

residual cyst age, site, gender

A

Age: Middle age or older
Site: More common in maxilla
Gender (Sex): More common in males

51
Q

Residual/Recurrent Cyst
Management

A

(same as PA cyst)
Requires removal of the cyst lining
Enucleation if a large cyst

52
Q

Fibrous Healing Defect (Apical Scar) Pathophysiology

A
  • 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
53
Q

fibrous healing defect Clinical

A
  • Asymptomatic
  • Noted in areas with a previous history of disease or trauma
54
Q

Fibrous Healing Defect radio app

A
  • 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
55
Q
A

fibrous healing defect

56
Q

Fibrous Healing Defect
(Apical Scar)
Management

A

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

57
Q

Neuroma, Neurofibroma
Clinical

A
  • Expansion, pain, or paresthesia
  • Symptoms include complaints of burning, tingling, and aching sensations
58
Q

Neuroma, Neurofibroma radio app

A
  • Well circumscribed radiolucency of various shapes
  • In the mandible it usually forms in the mandibular canal
59
Q
A

neuroma/neurofibroma

60
Q

Other Radiolucencies…

A

Many other odontogenic and non-odontogenic
lesions may manifest as solitary “cyst-like” radiolucencies.

Examples:
Odontogenic
*Amelobastoma
*Central giant cell granuloma
*Cementoossifying fibroma (early stage)
Non-odontogenic
*Chronic localized Langerhans’ cell disease
*Myeloma
