    摘要: A hand-held dental instrument is used for supporting a working tool and driving it according to a relative movement, including at least first fluid conveying means for conveying fluids through a body from the proximal end of the body towards fluid projection means. The first fluid conveying means include an upstream fluid conveying channel, a downstream fluid conveying channel, as well as a fluid collection radial chamber provided in the body between the upstream fluid conveying channel and the downstream fluid conveying channel. A filtration pin is mounted in the fluid collection radial chamber with a clearance allowing for the through-flow and the filtration of the fluids between the upstream fluid conveying channel and the downstream fluid conveying channel.
