Abstract
A dental compound applicator, having a shaft (1) that can be gripped in pencil-hold fashion, the front end of which can be connected to a syringe (4) containing the dental compound and a plunger, and containing a piston (6) for driving forward the plunger, which piston is connected to an actuation device (10) in that region of the shaft where a fingertip is located when gripping in pencil-hold fashion. The actuation device (10) comprises a toothed wheel which is mounted on the shaft, can be rotated by the fingertip and engages in a rack provided on the piston (6). The toothed wheel can consist of a larger grip wheel to be actuated using the finger, and a smaller pinion, cooperating with the rack, so that gearing down results.
