A method, system, device and an artificial tooth is disclosed for simulating both pain and anesthesia in a model of jaws. The tooth is equipped with sensors and connected to a data processing unit, memory unit and audiovisual display unit. The system is for teaching and practicing in the field of dentistry according to which removing artificial tooth or artificial bone substances by a dental drill, generates signals of pseudo pain with different intensities. Signals are fed to the data processing unit which simulates perception of the simulated pain and accordingly to said audio-visual display unit which simulates reaction to the different intensities of generated pseudo pain signals by playing different sounds which are stored in said memory unit. Furthermore, the system is able to simulate anesthesia by generating block signals as a result of applying different anesthetic techniques by means of a dental syringe connected to the system.

The present invention relates to a wireless remote control for dental equipment, such as dental scaler tools, dental drills, prophy angles and other rotary instruments.
