Summary
New direct digital radiography (RadioVisioGraphy or RVG) shows promise for detecting periapical lesions. While conventional radiography is better for subtle changes, RVG excels when lesions affect bone structure.
Area of Science:
- Dentistry
- Radiology
- Oral Pathology
Background:
- Radiographic density and gray-scale are key for bone pattern evaluation.
- Direct digital radiology systems like RadioVisioGraphy (RVG) allow contrast adjustment.
Purpose of the Study:
- To compare the diagnostic efficacy of RVG versus conventional radiography in detecting periapical lesions.
Main Methods:
- Periapical lesions were artificially created in human cadaver specimens.
- Specimens were radiographed using both conventional methods and RVG.
- Three endodontists evaluated the radiographic images for lesion detection.
Main Results:
- Conventional radiography was more diagnostic when no lesion was present (p < 0.05).
- RVG demonstrated superiority in detecting lesions involving the lamina dura and medullary bone (p < 0.05).
- No significant difference was observed between RVG and conventional radiography when lesions involved cortical bone.
Conclusions:
- RVG shows potential for diagnosing periapical lesions, particularly when they extend into medullary bone.
- The choice between RVG and conventional radiography may depend on the lesion's extent and characteristics.
- Further research may refine the application of RVG in endodontic diagnostics.
