In the early stages, which radiographic sign may be absent?

• A. No changes
• B. Loss of lamina dura
• C. Increased bone density around the apex
• D. Cortical plate expansion

Answer: (A)

In radiographic diagnosis, early pathology often doesn’t show up on the image because bone remodeling takes time and the pathological changes haven’t produced visible mineral loss or new bone formation yet. So, at the earliest stage the film can appear normal.

Loss of the lamina dura is a sign of periapical or inflammatory change but usually appears after the process has started to resorb surrounding bone. Increased bone density around the apex (sclerosis) or cortical plate expansion reflect later, more chronic or expanding processes. They only appear once the lesion has progressed enough to alter bone structure visibly.

Therefore, the most accurate statement for the earliest stage is that there may be no radiographic changes at all. If clinical suspicion remains, repeat imaging or advanced techniques can help detect evolving pathology.
