Abstract: A novel dental practice operation system affords computer controlled activation and control of a multitude of instrument operation and auxiliary functions by providing a plurality of distinct functionalities of at least one activation device for activation and control signals for a dental unit and a patient's rest. Increased efficiency for the dentist or dental team with increased integration of instrument control and auxiliary functions as well as operation of facilities provided by external sources is provided by simultaneous computer displayed guidance to the dentist of a first configuration of individually selectable symbols representing a number of distinct functionalities of the activation device and a second configuration of individually selectable symbols representing functions executable by a distinct functionality of the activation device made available by activation of a selected symbol in said first configuration.
