What causes a periapical radiolucency?
Most of periapical radiolucencies are the result of inflammation such as pulpal disease due to infection or trauma. Not all radiolucencies near the tooth root are due to infection. Odontogenic or non odontogenic lesions can over impose the apices of teeth.
What is meant by radiolucency?
[ra″de-o-loo´sen-se] the quality of permitting the passage of radiant energy, such as x-rays, yet offering some resistance to it, the representative areas appearing dark on the exposed film. adj., adj radiolu´cent.
What radiolucency means?
Radiolucency or hypodensity indicates greater passage (greater transradiancy) to X-ray photons and is the analogue of transparency and translucency with visible light.
What is radiopacity mean?
Radiodensity (or radiopacity) is opacity to the radio wave and X-ray portion of the electromagnetic spectrum: that is, the relative inability of those kinds of electromagnetic radiation to pass through a particular material.
What is radiopacity dental?
Objectives: Radiopacity of dental materials enables clinician to radiographically diagnose secondary caries and marginal defects which are usually located on the proximal gingival margin.
How is radiography used in a Panorex procedure?
Panorex imaging uses the radiographic technique called tomography. During a panoramic procedure, the radiation source and image receptor rotate around the patient’s head in opposite directions while the patient remains stationary. This rotation produces a radiograph by imaging one area of the orofacial region while blurring other areas.
What are the different types of radiopaque jaw lesions?
Radiopaque Jaw Lesions: An Approach to the Differential Diagnosis 1 Cementoblastoma. If a lesion is periapical, the differential diagnosis includes cementoblastoma,… 2 Cemento-osseous Dysplasia. Cemento-osseous dysplasia represents a hamartomatous process… 3 Condensing Osteitis. Condensing osteitis occurs in children and young adults,…
Where is the focal trough in a Panorex image?
The focal trough is an arciform area between the radiation source and image receptor. The maxilla and mandible must be positioned in the focal trough to create a detailed and diagnostic-quality panoramic image.
What is the differential diagnosis of a periapical lesion?
If a lesion is periapical, the differential diagnosis includes cementoblastoma, cemento-osseous dysplasia, and condensing osteitis. If it is pericoronal, odontoma should be considered (Table 1).
