Abstract

A syringe for treating gums includes a cylinder in which a piston is reciprocally mounted. The fluid for treating the gums is located in the cylinder and is expelled from a spout, such as a cannula or other replaceable reusable thin irrigating tip. The tip would have a rounded end if made of metal and would be softer if made of plastic thus rendering it relatively harmless, while thin enough to provide access to the deepest regions of the periodontal pocket and deposit/irrigate effective antibacterial agents so as to eradicate periodontal disease associated micro-organisms. Fluid is discharged by depressing the piston into the cylinder. A resilient member reacts means react between the piston and the cylinder to urge the piston into the cylinder. The user may control the amount of inward movement by manually restraining the piston.

Claims

1. A method of treating a user'"'"'s gums comprising the steps of supplying a treatment fluid into the cylinder of a syringe with the plunger of the syringe extending outwardly from the cylinder and with the cylinder having a front hub portion remote from a notched end plate at the outer end of the plunger, attaching a rubberband to the hub and to the end plate to create a resilient force when the plunger is fully extended from the cylinder to urge the plunger into the cylinder, resisting the inward movement of the plunger by the user applying resistance to the syringe to resist the resilient force of the rubberband, the user inserting the blunt end of the applicating tip of the syringe into a gum pocket of the user, releasing the resistance to permit movement of the plunger into the cylinder and force the treatment fluid out of the applicating tip and into the gum pocket, and flushing the gum pocket with the treatment fluid.
