Minimal dentinal destruction to get evident on the radiograph
1) 30 microns
2) 40 microns
3) 200 microns
4) 300 microns
Radiology
Answer: 2
Radiographic detection of carious lesions or dentinal destruction typically requires a certain threshold of loss of tooth structure. Studies have shown that a loss of approximately 40 microns of dentin is necessary for a radiograph to show evidence of carious lesions.
