Abstract
One or more dental instruments are connected by flexible supply lines to a dental unit. A retractor is arranged to pull an extended instrument back to the unit upon being triggered. The dental instrument carries a magnet. A magnetic sensor is located near the retractor. When the instrument is passed near to sensor a signal activates the retractor which pulls in the instrument.
