Abstract
The specification describes an applicator for the treatment of teeth with small amounts of polymerizable material. The applicator is in the form of an elongated member having an applicator head which contains a chamber enclosing a similarly-shaped resilient member. A closure fits over the end of the applicator head and serves to close off the base of the chamber and seal the peripheral edge of the resilient member to prevent leakage. The closure is provided with a smaller chamber which communicates with a channel extending out through the closure and adapted to receive a disposable tube. The channel is positioned at an angle to the main body of the applicator. The applicator is provided with a movable lever-operated piston which presses on the resilient member for drawing liquid into and dispensing liquid from a disposable tube after the same has been inserted into the applicator head.
