Abstract
A dental handpiece has two sleeves rotatable relative to each other about a longitudinal axis. A chuck for a burr is driven by a gas turbine mounted in one of the sleeves. Air to drive the turbine is conducted through both sleeves by passages having a joint swivelling about the axis. Similarly, light, cleansing air and water are carried to the turbine vicinity and through swivel connections so that relative rotation of the handpiece sleeves can always be accomplished without interrupting any of the flows between the two sleeves.
