A computer-implemented dental charting system includes a computer storing tooth data for at least one patient and a display operable to display the tooth data. The computer is responsive to voice commands, and the display has a periodontal mode and a restorative mode. The display includes an exam overview window illustrating a plurality of tooth images, each tooth image corresponding to a patient tooth location, and an exam focus window. The exam focus window illustrates a magnified view of at least one of the plurality of tooth images, and illustrates data corresponding to the selected tooth location. The exam focus window may be displayed beside the exam overview window, as a floating window on top of the exam overview window, or on a physically separate display from the exam overview window.
