17
Q

Solitary (traumatic) Bone Cyst
Radiographic
(3)

A

Unilocular
radiolucency with
interradicular
scalloped superior
margins
Usually >10mm and
associated with > 1
root apex
Aggressive lesions
can be expansive

18
Q

Solitary (traumatic) Bone Cyst
Age
Site
Gender

A

Usually <25 years; but not absolute, Second decade
Body and ramus of mandible
No predilection

19
Q

Solitary (traumatic) Bone Cyst
Management
Other

A

Initiate bleeding
Recurrence is rare

20
Q

Posterior Lingual Mandibular
Salivary Gland Depression
Radiographic

A

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

21
Q

Posterior Lingual Mandibular
Salivary Gland Depression
Age
Site
Gender

A

Adults; prominent over 50 years
Between the mandibular canal and inferior border
Almost exclusively male predilection

22
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

23
Q

Focal Osteoporotic Bone
Marrow Defect of the Jaws
Clinical

A

Asymptomatic

24
Q

Focal Osteoporotic Bone
Marrow Defect of the Jaws
Radiographic
(2)

A
  • Unilocular, faint
    radiolucency
  • Not ragged but
    difficult to discern as
    a separate entity
25
Q

Focal Osteoporotic Bone
Marrow Defect of the Jaws
Age
Site
Gender (Sex)
Management

A

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

26
Q

Residual/Recurrent Cyst
Pathophysiology
(2)

A

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

27
Q

Residual Cyst
Clinical
(2)

A

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

28
Q

Residual Cyst
Radiographic
(3)

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
29
Q

Residual Cyst
Age
Site
Gender (Sex)

A

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

30
Q

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

A

Requires removal of the cyst lining
Enucleation if a large cyst

31
Q

Fibrous Healing Defect
(Apical Scar)
Pathophysiology
(3)

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
32
Q

Fibrous Healing Defect
(Apical Scar)
Clinical
(2)

A
  • Asymptomatic
  • Noted in areas with a previous
    history of disease or trauma
33
Q

Fibrous Healing Defect (Apical Scar)
Radiographic
(3)

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
34
Q

Fibrous Healing Defect (Apical Scar)
Management
(2)

A

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

35
Q

Neuroma, Neurofibroma
Clinical
(2)

A
  • Expansion, pain, or paresthesia
  • Symptoms include complaints of burning,
    tingling, and aching sensations
36
Q

Neuroma, Neurofibroma
Radiographic
(2)

A
  • Well circumscribed
    radiolucency of
    various shapes
  • In the mandible it
    usually forms in the
    mandibular canal
37
Q

Neuroma, Neurofibroma
Management

A

Excision, recurrence is rare

38
Q

skipped
Many other odontogenic and non-odontogenic
lesions may manifest as solitary “cyst-like”
radiolucencies.
Examples:
Odontogenic
(3)

A

*Amelobastoma
*Central giant cell granuloma
*Cementoossifying fibroma (early stage)

39
Q

skipped
Many other odontogenic and non-odontogenic
lesions may manifest as solitary “cyst-like”
radiolucencies.
Examples:
Non-odontogenic
(2)

A

*Chronic localized Langerhans’ cell disease
*Myeloma
