What will be an ideal response?
The same as a healthy status. The lamina dura appears as an uninterrupted, continuous, dense radiopaque line around the roots of the teeth. As gingivitis is a disease of soft tissue only, there are no radiographic changes and the lamina dura appears the same as in a healthy periodontal status.
