scalloped superior
margins
Usually >10mm and
associated with > 1

Recurrence is rare
Posterior Lingual Mandibular
Salivary Gland Depression
Radiographic
Well circumscribed
posterior radiolucency
in molar region
between mandibular
canal and inferior
border
Posterior Lingual Mandibular
Salivary Gland Depression
Age
Site
Gender
Adults; prominent over 50 years
Between the mandibular canal and inferior border
Almost exclusively male predilection
Posterior Lingual Mandibular
Salivary Gland Depression
Management
Positive diagnosis based on clincial and
radiologic history negates the need for biopsy
and histologic examination
Focal Osteoporotic Bone
Marrow Defect of the Jaws
Clinical
Asymptomatic
Focal Osteoporotic Bone
Marrow Defect of the Jaws
Radiographic
(2)
- Unilocular, faint
radiolucency - Not ragged but
difficult to discern as
a separate entity

Age

Gender (Sex)
Management
All
Mandible
Slightly higher in females but No
predominant gender
No treatment
Residual/Recurrent Cyst
Pathophysiology
(2)
Results from incomplete removal or
residual viable epithelial cystic lining
following treatment of a cyst
Previous history of periapical disease
Residual Cyst
Clinical
(2)
Asymptomatic, normally
found on radiographic
examinations of
edentulous areas
Tooth or root may or may
not be present
Residual Cyst
Radiographic
(3)
- 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
Residual Cyst
Age
Site
Gender (Sex)
Middle age or older
More common in maxilla
More common in males
Residual/Recurrent Cyst
Management (same as PA cyst)
(2)
Requires removal of the cyst lining
Enucleation if a large cyst
Fibrous Healing Defect
(Apical Scar)
Pathophysiology
(3)
- 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
Fibrous Healing Defect
(Apical Scar)
Clinical
(2)
- Asymptomatic
- Noted in areas with a previous
history of disease or trauma
Fibrous Healing Defect (Apical Scar)
Radiographic
(3)
- 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
Fibrous Healing Defect (Apical Scar)
Management
(2)
No treatment indicated
A previous history of disease is critical in
establishing the diagnosis
Neuroma, Neurofibroma
Clinical
(2)
- Expansion, pain, or paresthesia
- Symptoms include complaints of burning,
tingling, and aching sensations
Neuroma, Neurofibroma
Radiographic
(2)
- Well circumscribed
radiolucency of
various shapes - In the mandible it
usually forms in the
mandibular canal
Neuroma, Neurofibroma
Management
Excision, recurrence is rare
skipped
Many other odontogenic and non-odontogenic
lesions may manifest as solitary “cyst-like”
radiolucencies.
Examples:
Odontogenic
(3)
*Amelobastoma
*Central giant cell granuloma
*Cementoossifying fibroma (early stage)
skipped
Many other odontogenic and non-odontogenic
lesions may manifest as solitary “cyst-like”
radiolucencies.
Examples:
Non-odontogenic
(2)
*Chronic localized Langerhans’ cell disease
*Myeloma
