A key feature to tablet PCs  is the use of touch screens and inking. That means a user can easily enter information by tapping on the screen with one hand while holding the tablet in another. Ink allows users to write or draw on the screen just as if it was a piece of paper.

This allows dentists to draw on the electronic dental chart just like we used to do on the paper charts. It also allows for ink capable forms. A patient does not fill out a paper form but is handed a tablet and fills out the form using a stylus and ink. And then the patient or dentist can sign the electronic chart using ink.
