A dental equipment stand with an adjustable multi-component carrying arm for a dental mounting component, wherein the carrying arm consists of two hingedly interconnected pivot arms, of which the first pivot arm is arranged to be pivotable about a pivot bearing at the end remote from the second pivot arm so as to be pivotable about a horizontal axis. The pivot bearing is, in turn, supported in a carrying component so as to be rotatable about a vertical axis, and in which the second pivot arm at its free end supports the mounting component. The mounting component which is arranged at the free end of the second pivot arm so as to be pivotable can, for example, be a holder for dental instruments, a repository plate with, possibly, a holder located thereon for dental instruments, or the like. The carrying component which includes the pivot bearing can be arranged stationarily or movably on the floor or, for example, as a console on the wall, on the ceiling or on a professional furniture piece, for instance, on a cabinet or on a writing desk.
