Abstract
A device for alerting a dentist when the angular position of the drill and the angular position of the tooth being drilled do not correspond so that during drilling the angular position of the hole being drilled does not change. The device includes a drill transducer, a tooth transducer, a central control unit, and an alarm. The drill transducer is attachable to a dental drill and generates a drill angular position signal representing an angular position of the dental drill. The tooth transducer is removably attachable to a tooth and generates a tooth angular position signal representing an angular position of the tooth. The central control unit compares the drill angular position signal and the tooth angular position signal to each other to determine if the difference is within the value of a predetermined difference angular position. And, the alarm alerts when the drill angular position signal and the tooth angular position signal do not correspond with each other within the value of the predetermined difference angular position so that repositioning of the drill can be initiated.
