solitary bone cyst additional names
Unicameral Bone cyst Solitary Bone Cyst* Hemorrahgic Bone Cyst* Intravasational Bone Cyst Traumatic Bone Cyst * Extravasational Bone Cyst
26
traumatic bone cyst radio app
Unilocular radiolucency with interradicular scalloped superior margins Usually >10mm and associated with > 1 root apex
27
traumatic bone cyst
28
differential? (this class content only)
lat perio cyst traumatic bone cyst
29
traumatic bone cyst aggressive lesions?
can be expansive
30
traumatic bone cyst age, site, gender
Age: Second decade, Usually <25 years; but not absolute Site: Body and ramus of mandible Gender: No predilection
31
solitary bone cyst tx
iniate bleeding
32
solitary bone cyst recurrence
rare
33
Posterior Lingual Mandibular Salivary Gland Depression (stafne cyst) clinical
Asymptomatic, usually found in routine radiographic examinations
34
stafne cyst
35
Posterior Lingual Mandibular Salivary Gland Depression radio app
Well circumscribed posterior radiolucency in molar region between mandibular canal and inferior border
36
Posterior Lingual Mandibular Salivary Gland Depression
37
Posterior Lingual Mandibular Salivary Gland Depression
38
stafne cyst on PA
39
how could stafne cyst be confirmed
radio dye into whartons duct
40
Posterior Lingual Mandibular Salivary Gland Depression age, site, gender
Age: Adults; prominent over 50 years Site: Between the mandibular canal and inferior border Gender: Almost exclusively male predilection
41
Posterior Lingual Mandibular Salivary Gland Depression management
Positive diagnosis based on clincial and radiologic history negates the need for biopsy and histologic examination
42
Focal Osteoporotic Bone Marrow Defect of the Jaws clinical symptoms
asymptomatic
43
Focal Osteoporotic Bone Marrow Defect of the Jaws radio app
* Unilocular, faint radiolucency * Not ragged but difficult to discern as a separate entity * loss of trabeculae
44
focal osteoporotic bone defect
45
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
Focal Osteoporotic Bone Marrow Defect of the Jaws management
no tx
47
Residual/Recurrent Cyst Pathophysiology
Results from incomplete removal or residual viable epithelial cystic lining following treatment of a cyst Previous history of periapical disease
48
Residual Cyst Clinical
Asymptomatic, normally found on radiographic examinations of edentulous areas Tooth or root may or may not be present
49
residual cyst radio app
* 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
residual cyst age, site, gender
Age: Middle age or older Site: More common in maxilla Gender (Sex): More common in males
51
Residual/Recurrent Cyst Management
(same as PA cyst) Requires removal of the cyst lining Enucleation if a large cyst
52
Fibrous Healing Defect (Apical Scar) Pathophysiology
* 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
fibrous healing defect Clinical
* Asymptomatic * Noted in areas with a previous history of disease or trauma
54
Fibrous Healing Defect radio app
* 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
fibrous healing defect
56
Fibrous Healing Defect (Apical Scar) Management
No treatment indicated A previous history of disease is critical in establishing the diagnosis
57
Neuroma, Neurofibroma Clinical
* Expansion, pain, or paresthesia * Symptoms include complaints of burning, tingling, and aching sensations
58
Neuroma, Neurofibroma radio app
* Well circumscribed radiolucency of various shapes * In the mandible it usually forms in the mandibular canal
59
neuroma/neurofibroma
60
Other Radiolucencies...
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
