An accessory for use in pricking depth-indicating washers on to dental reamers comprises a body constituting a receptacle. The washers which are located in the receptacle are brought into a free space of the body within which they are juxtaposed. They successively engage a notch in a movable small plate, constituting a distributor element, which enables the washer located in the notch, by transverse sliding of the small plate, to be brought opposite to a hole of the body. The washer thus placed can easily be pricked by a dental canal reamer passing through a hole provided in the cover of the accessory and which is situated opposite to the hole of the body. The diameter of this hole is greater than that of the washers to allow the washer which is pricked on the spindle to be withdrawn from the receptacle.
