With a dental apparatus comprising several instruments (8) connected to a power supply panel (11) by helicoidal flexible lines (4) fixed at the upper level (2) to the apparatus, and provided at the lower level (6) with a rack for the instruments (8), it is desired to have the possibility of easily withdrawing each instrument from the rack or of putting it back into the rack without moving the other instruments. It is proposed to locate the power supply panel at the top level (2), to provide each supply flexible line with an individual anchoring point to the apparatus, situated in its connection to the power supply panel, to give each flexible line a helicoidal shape along its entire length between the power supply panel at the top level and the instrument kept at the lower level (8), to render the helicoidal portion of the supply flexible line between the connection panel and the instrument substantially rectilinear, when at rest, and slightly inclined with respect to the vertical, and to sling the instruments in notches in the rack (5) by means of elements of appropriate shape (9) located at the extremity of the supply lines adjacent to the instruments or on the instruments themselves.
