A clamp usable by dentists to retain a rubber dam in a depressed position so as to isolate a tooth being worked on from mouth saliva and moisture. The clamp is constituted by a bow spring whose legs are joined to jaws adapted to grip the tooth, the spring being so biased as to normally spread the jaws apart. Associated with the legs of the spring is a trigger mechanism which, when the legs of the bow spring are pressed together to cause the jaws to grip the tooth, acts to lock the jaws in this position, and at the same time to cock the trigger, the mechanism including a trigger pin passing through a hole in the yoke of the bow springs. When this pin is actuated, the jaws are immediately spread apart by the released spring tension.

A dental tool for measuring, triturating and dispensing amalgam having a hand piece holding a reciprocable chamber into which the amalgam ingredients are metered and then shaken is provided with an opening through which the triturated amalgam can be dispensed into a cavity. A pin mounted in the receptacle can be used to valve the passageway out of the receptacle and functions also as a tamper when the receptacle is reciprocated for tamping dispensed amalgam into a cavity.
