Inflammatory
Neoplastic
Congenital
Metabolic
Which category of pathology can look similar to osteomyelitis?
Malignant Tumor
Benign Cyst
Viral Infection
Metabolic Disorder
Fibrous Dysplasia, Cemento-osseous dysplasia, and benign tumor with fibro-osseous characteristics are examples of which pathology category?
Fibro-osseous
Odontogenic cysts
Vascular lesions
Epithelial tumors
What is the typical periphery of a cyst?
WD, corticated
ID
WD or ID
Not specified
Which category is classically characterized by 'teeth floating in air' as a specific feature?
Malignancy
Cystic lesions
Benign tumors
Inflammatory conditions
Gross displacement favors benign tumors.
True
False
Which category rarely displaces or resorbs roots and may show teeth floating in air?
Malignancy
Cyst
Benign tumor
Fibrous dysplasia
Look at the dental X-ray image with red arrows pointing to a large radiolucent area above the roots of the teeth. What is the most likely diagnosis?
Abscess
Cyst
Tumor
Fracture
Fill in the blank: A cyst is defined as a ________ lined by epithelium and surrounded by a connective tissue wall.
fluid-filled cavity
solid mass
vascular bundle
bony projection
Cysts occur more often in which bone than any other bone because they can develop from remnants of odontogenic epithelium?
Femur
Jaws
Skull
Ribs
Which of the following is NOT a clinical feature of cysts?
Swelling
Lack of pain (unless secondarily infected or related to nonvital tooth)
Associated with unerupted teeth, especially third molars
High fever
What is the typical internal structure of cysts?
Radiolucent. May have septa – multilocular appearance; Scalloping may appear to be septation.
Radiopaque with dense calcifications throughout.
Solid mass with no internal spaces or septa.
Completely opaque with no evidence of septation or scalloping.
What is the effect of cysts on other structures?
Slow-growing, can displace structures. Expands sinus border and cortical plates. Can resorb roots of teeth.
They cause immediate severe pain and bleeding in all cases.
Cysts always shrink and never affect surrounding tissues.
They only affect soft tissues and never involve bone.
What does the term 'Hydraulic' mean in the context of cysts?
Since cysts are fluid-filled, the shape will imitate a water balloon; potentially round, or spherical, but they can be influenced by the shape of surrounding structures.
It refers to the presence of solid material within the cyst.
It means the cyst is always irregular in shape regardless of its contents.
It describes cysts that are filled with air instead of fluid.
What is the likely diagnosis of the lesion in this image?
Periapical cyst
Focal cemento-osseous dysplasia
Cementoblastoma
Hypercementosis
What is the likely diagnosis of the lesion in this image?
Periapical cyst
Focal cemento-osseous dysplasia
Cementoblastoma
Hypercementosis

mesial
Refer to the radiograph labeled B. What is lacking due to secondary infection?

Wide root canal
Cortical border
Apical epicenter
What is the typical location of a residual cyst in the mandible?

Odontogenic keratocyst
Ameloblastoma

resorbed
fractured
displaced
calcified

Periapical abscess
Dentigerous cyst growing into the ramus
Ameloblastoma
Odontogenic keratocyst
What does the radiograph show?
Periapical abscess
Dentigerous cyst expanding distally from the third molar
Ameloblastoma
Odontoma
