Study Notes
Radiographic Features of Jaw Lesions
- Fibrous dysplasia can present with various internal patterns including granular, ground-glass, cotton-wool, and orange-peel patterns.
- Fibrous dysplasia can cause expansion and displacement of surrounding structures, such as the mandible and maxilla, as well as the inferior alveolar nerve canal.
- Fibrous dysplasia can lead to changes in bone pattern, root resorption, and hypercementosis in affected teeth.
- Periapical osseous dysplasia predominantly affects middle-aged females and is more common in blacks, with a predilection for the periapical bone of mandibular anterior teeth.
- Periapical osseous dysplasia can develop at the apex of a vital tooth, leading to the loss of lamina dura and widening of the periodontal membrane space.
- Periapical osseous dysplasia presents with well-defined, irregularly shaped lesions with a radiolucent border and sclerotic bone band.
- Florid osseous dysplasia, prevalent in African Americans and Asians, can displace the inferior alveolar nerve canal and cause enlargement of the alveolar bone.
- Florid osseous dysplasia can exhibit radiopaque regions with cotton-wool appearance and prominent radiolucent regions, potentially leading to displacement of the floor of the antrum.
- Central giant cell granuloma primarily affects individuals younger than 20 years, with lesions developing more frequently in the mandible.
- Central giant cell granuloma shows well-defined radiographic margins in the mandible and may have ill-defined borders in the maxilla.
- Internal structure of central giant cell granuloma may exhibit a soap bubble appearance and uneven expansion with indentation, leading to displacement and resorption of teeth.
- Central giant cell granuloma can displace the inferior alveolar canal and cause the lamina dura of affected teeth to be missing.
Jaw Lesions and Their Characteristics
- Aneurysmal Bone Cyst (ABC) is found in individuals younger than 30 years old, with a predilection for females, occurring more in the mandible than the maxilla, often affecting the molar and ramus regions.
- ABCs have a well-defined circular shape, and when large, they cause extreme expansion of the outer cortical plates, displacing and resorbing teeth.
- Cherubism, occurring between 2 and 6 years of age, presents as painless, bilateral enlargement of the lower face, affecting the mandible's posterior aspect, with a classic "eyes raised to heaven" appearance due to maxilla swelling.
- Cherubism has a multilocular pattern and causes expansion of the maxilla and mandible, displacing teeth in an anterior direction and destroying tooth buds in some cases.
- Paget's Disease commonly occurs in individuals older than 40, affecting men twice as commonly as women, leading to enlargement and deformation of affected bones, including the skull, pelvis, femur, and vertebrae.
- Paget's Disease results in malocclusion, tight or poorly fitting dentures, and neurologic pain due to bone impingement on nerve canals, often accompanied by elevated levels of serum alkaline phosphatase and hydroxyproline in the urine.
- Fibrous Dysplasia, Florid Osseous Dysplasia, and Langerhans' Cell Histiocytosis (LCH) are differential diagnoses for jaw lesions, with LCH commonly occurring in older children and young adults, often in the mandible's posterior regions.
- LCH may present as a single or multifocal, aggressive disease, and the disseminated form may involve multiple bone lesions, diabetes insipidus, and exophthalmos.
- Fibrous Dysplasia presents as expanding, irregular, radiolucent lesions, and may cause loosening or sloughing of teeth after destroying alveolar bone.
- Florid Osseous Dysplasia affects the mandible more than the maxilla, with a cotton-wool appearance on imaging, and prominent pagetoid skull bones that may swell to three or four times their normal thickness.
- The lesions of Fibrous Dysplasia, Florid Osseous Dysplasia, and LCH can have a scooped-out shape and vary from moderately to well defined peripheries without cortication.
- These jaw lesions have distinct characteristics, affecting different age groups and genders, with specific patterns of expansion, internal structure, and effects on surrounding structures.
