Study Notes
Radiographic Examination
- Radiographs are essential for diagnosing lesions near or within bone after clinical assessments.
- They can indicate osseous reactions, erosion, or intraosseous origins of soft tissue lesions.
- Standard radiographic techniques include periapical, occlusal, and panoramic views; specialized imaging may require computed tomography (CT) or magnetic resonance imaging (MRI).
- Cysts typically present as radiolucencies with clear borders, while aggressive lesions feature ragged, irregular borders.
- Deviation from normal structures in radiographs necessitates distinguishing between pathologic changes and atypical normal anatomy, especially in complex areas like the maxilla and mandible.
- Radiopaque dyes (e.g., sialography) can help evaluate gland structures and pathologic lesions.
- Injection of radiopaque substances into cysts can enhance determination of anatomical boundaries.
- Localization of foreign objects or lesions may involve radiopaque markers like needles or metal spheres.
Laboratory Investigation
- Laboratory tests can be crucial for identifying the systemic disease-related oral lesions.
- Conditions such as hyperparathyroidism, multiple myeloma, leukemia, and lymphomas may manifest as oral lesions.
- For instance, multiple lytic lesions and loss of the lamina dura may indicate hyperparathyroidism, which can be confirmed with serum calcium, phosphorus, and alkaline phosphatase tests.
- References for test requests and guidelines are available in oral and maxillofacial pathology textbooks.
