Claim 15

A periodontal implement for applying a medicinal fluid to the tissue in a patient's mouth adjacent teeth to be treated comprising, a handle having opposite ends, a first blade extending outwardly from one of said ends, a second blade extending outwardly from the opposite end of said handle, a first shank for connecting said first blade to said handle, a second shank for connecting said second blade to said handle, a first fluid passageway within said handle, said first fluid passageway extending through said handle and said first shank, a first opening in said first shank which communicates with said first fluid passageway, said first opening being oriented so as to discharge fluid to said first blade, a second fluid passageway extending through said handle and said second shank, a second opening in said second shank communicating with said second fluid passageway, fluid inlet means for supplying a source of fluid to said first and second fluid passageways, said means for supplying fluid includes a valve means mounted within said handle, said valve means being rotateable between a first and a second position and including an inlet and an outlet passageway, said outlet passageway of said valve means communicating with said first fluid passageway when in said first position and communicating with said second fluid passageway when in said second position.

Claim 16

The periodontal implement of claim 13 in which said first and second blades include upper and lower surfaces, said upper surface being generally concave.

Claim 17

The periodontal implement of claim 14 in which said first and second blades have at least one opening therethrough between said upper and lower surfaces.

Claim 18

The periodontal implement of claim 15 in which said first and second blades include outer edges, said outer edges being generally rounded.

Claim 19

The periodontal implement of claim 16 including grooves in said outer edges of said first and second blades.

Claim 20

The periodontal implement of claim 13 in which said means for supplying a source of fluid also includes a fluid conduit selectively connected to said inlet of said valve, a fluid reservoir, and means for applying pressure to said fluid reservoir so as to discharge fluid therefrom and through said conduit into the implement by way of said valve.

Claim 21

A periodontal implement for applying a medicinal fluid to the tissue in a patient's mouth adjacent teeth to be treated comprising, a handle having at least one blade extending therefrom, a shank for connecting said blade to said handle, a fluid passageway within said handle, said fluid passageway extending within said shank, an opening in said shank which communicates with said fluid passageway, said opening being oriented so as to discharge fluid to said blade, said blade having opposite edge portions, and a plurality of grooves formed in said edge portions of said blade.
