Solitary Radiolucencies Flashcards
Most likely cyst seen on line of fusion
-Usually in midline
Incisive canal cyst
• Painless swelling • Sinus tract may be present • Unilocular radiolucency in vicinity of maxillary midline • Cause alterations to walls of incisive canals • Root divergence in cases of large cysts Age 4th and 6th decades Site Anterior maxilla; close to midline Gender Male:Female 3:1 Management Enucleation Other Recurrence unusual
Incisive canal cyst
Clinical Asymptomatic Radiographic Unilocular radiolucency in the symphyseal region of the mandible - Very rare
Median Mandibular Cyst
Clinical Asymptomatic Radiographic • Unilocular radiolucency • Palatal midline, posterior to papilla Midpalate posterior to papilla -Rare Treat via enucleation
Mid palatine cyst
Asymptomatic, dome-shaped swellings of the interdental papilla, attached gingiva, or alveolar mucosa. • Well defined radiolucency • Round to ovoid • Normally in inter- radicular areas between alveolar crest and apices • May or may not come in contact with the root surface Age (middle aged) Adult Site Mandible – Canine–premolar region Gender (Sex) Male Management Enucleation Other The cyst does not recur Must be differentiated from early stage OKC’s and ameloblastomas
Lateral periodontal cyst
Clinical Normally asymptomatic, may have swelling or pain. Radiographic Unilocular radiolucency with interradicular scalloped superior margins Usually >10mm and associated with > 1 root apex Aggressive lesions can be expansive Age Second decade Usually <25 years; but not absolute Site Body and ramus of mandible Gender (Sex) No gender predilection Management Initiate bleeding Other Recurrence is rare
(Traumatic) Solitary Bone Cyst
Clinical
Asymptomatic, usually found in routine radiographic examinations
Well circumscribed posterior radiolucency in molar region between mandibular canal and inferior border
Age
Adults; prominent over 50 years
Site
Between the mandibular canal and inferior border
Gender (Sex)
Male predilection
Management
Positive diagnosis based on clinical and radiologic history negates the need for biopsy and histologic examination
Posterior Lingual Mand Salivary Gland Depression
• Unilocular, faint radiolucency • Not ragged but difficult to discern as a separate entity Age All Site Mandible Gender (Sex) Slightly higher in females but No predominant gender No treatment
Focal Osteoporotic Bone Marrow Defect of the Jaws
