Radiographic Interpretation
Radiographic Interpretation
Radiographic interpretation focuses on analyzing the radiographic image to identify abnormalities and potential pathologies.
Interpretation vs. Diagnosis
Interpretation vs. Diagnosis
Radiographic interpretation involves identifying features on a radiograph, while diagnosis is the final conclusion based on all available information, including clinical and radiographic findings.
Radiographic Terminology
Radiographic Terminology
Terms like radiolucent, radiopaque, unilocular, and multilocular are used to describe the appearance of structures on radiographs, aiding interpretation.

Study Notes
Radiographic Interpretation
- Importance of interpretation of radiographic image
- Difference between interpretation and diagnosis
- Understanding different radiographic terminologies
Radiolucent and Radiopaque Lesions
- Radiolucent lesions:
- Appear dark or black on film
- Examples: air space, soft tissues, dental pulp, periodontal ligament space
- Radiopaque lesions:
- Appear white or light on film
- Examples: metal restoration, enamel, dentin, bone
Terms Used to Describe Radiolucent Lesions
- Unilocular radiolucent lesion:
- Single radiolucent compartment
- Unilocular lesion with corticated border:
- Radiolucent compartment with a thin, well-demarcated radiopaque rim of bone
- Unilocular lesion with non-corticated border:
- Radiolucent compartment without a radiopaque rim of bone
- Multilocular radiolucent lesion:
- Multiple radiolucent compartments
- Exhibit well-defined corticated margins
Location of Lesions
- Periapical location:
- Area around the apex of the root
- Inter-radicular location:
- Area between the roots of adjacent teeth
- Edentulous zone:
- Area without teeth
- Pericoronal location:
- Area around the crown of an impacted tooth
Size and Shape of Lesions
- Size: varies from millimeter to several centimeters in diameter
- Shape:
- Unilocular: round, oval, or scalloped
- Multilocular: irregular or honeycomb appearance
Radiographic Features of Lesions
- Effect on adjacent surrounding structure:
- Teeth: resorption, displacement, delayed eruption, disrupted development
- Bone: expansion, alteration in size of pulp chamber, hypercementosis
- Relative radio-density and internal structure:
- Uniformly radiolucent
- Mixed radiopaque
Benign and Malignant Lesions of the Jaws
- Benign odontogenic tumors:
- Ameloblastoma
- Calcifying epithelial odontogenic tumor
- Adenomatoid odontogenic tumor
- Odontoma
- Ameloblastic fibroma

- Odontogenic myxoma
- Benign cementoblastoma
- Malignant lesions of the jaws:
- Not discussed in this text
Specific Lesions

- Bony protuberance in the middle third of the hard palate
- Can vary in size and shape
- Can cause cortical expansion
- Torus mandibularis:
- Bony growth on the lingual surface of the mandible
- Can cause cortical expansion
- Odontogenic myxoma:
- Multilocular radiolucency with angular septa
- Can cause cortical expansion and facial asymmetry
- Benign cementoblastoma:
