Abstract
The invention relates to a dental coupling unit (), which can be detachably coupled to an instrument attachment () for dental treatment and/or examination at the front end () of the coupling unit and also can be connected to a supply unit () for providing supply media for the instrument attachment (), wherein a media supply line () extends through the coupling unit () toward the instrument attachment () and wherein additionally a media return line () extends through the coupling unit (), which media return line is connected to an end region of the media supply line () extending through the coupling unit (), which end region faces the instrument attachment (). The coupling unit () has a valve assembly (), which conducts the liquid from the coupling unit () to the instrument attachment () when the instrument attachment () is attached and conducts the liquid to the media return line () and blocks the escape of the liquid at the front end () of the coupling unit () when the instrument attachment is not attached.
