Palpation gives information as to
1. induration.
2. tenderness.
3. size.
4. fixation.
5. mobility.

The oral examination of the edentulous patient should include digital palpation because
1. the arch form can be more accurately evaluated.
2. the thickness of the mucosa can better be evaluated.
3. undercut areas may be hard to visualize.
4. spicules under the mucosa may be overlooked.
5. the ridge relationship will be better understood
