BACKG~.OUND OF THE INVENTION
FJELD OF THE INVENTION .
This invention relates to a hand-held device for dispensi.ng medicaments into subgingival pockets for .
the prevention and treatment of periodontitis.
t DESCRIPTION OF THE PP.IOR ART
.
.Periodontitis is the major cause o~ tooth loss in adults. Primary among regimens to combat periodontitis is the maintenance of an oral environment that is free of food debris, desquamated or shed ti.ssue and bacteria. Brushing the teeth t~ith a. toothbrush and . toothpaste helps in keeping the oral cavity clean; but is less effective in removing debris or bacteria-laden plaque from between the teeth, and has little effect in the subgingival pockets. Plaque remaining ln the subgingival pockets results in gingi.vitis, an inflammation which is recognized to be the precursor to periodonti.tis.
Medicaments are ava.ilable which kill the bacteria in plaque and aid in reducing gingivitis and ( ~ 2~2 ~
periodontitis. However, it is difficult for the consumer to apply these materials to the subgingival areas in a ho~e environment. In recogn3tion of this problem, one manufacturer has devised an appliance called the ''Water Pik" that uses pressurized water through a small hand-held nozzle, which impinges against the teeth and gums and helps remove food debris. However, this appliance is not suitable or convenient for delivering medicaments to the subgingival pock.ets, which will remain in the poc~.ets.
The present invention has the capability of delive~ing viscous or gelled medicaments to subgingival pockets and gingival margins for the treat~ent of gingivitis and periodontal diseases.
The present invention is an improvement over United States Patent~No. 4,617,918.
SUMMARY OF THE INVENTION
The present invention is a hand-held squeezable tube filled with appropriate medication which has the rheology of a gel and is dispensed through a physiologically angled extension tube fitted with a flexible rubber or plastic tip containing an appropriately sized orifice.
The device is used by removing the protective cap covering the flexible tip. The flexible : f-:` ~ 2~2~2~
tip is then inserted into the proximal areas pointing towards the subgingival pocket l~ith the device in thjs position, the tip is gently pressed into the subgingival .
pocket, while squeezing the tube, forcing the medication through the extension tube and flexible tip into the subgingival pocket. This procedure is repeated on the lingual and buccal sides of each tooth including the gingival margin.

, ~ ~ 202~2~
DETAILED DESCRIPTION OF THE ~NVENTION
With continuing reference to the accompanying drawings, wherein like reference numerals designate similar parts throughout the various views, reference numeral 10 generally designates a hand-held device for combatting periodontitis in accordance with the concep~ts of the present invention.
The ~evice 10 includes a housing 12 having a threaded opening 14 for receiving an externally threaded neck 16 of a squeezable tube containing a medicament. The tube 10 may be formed of a plastic or metallic material and may be of a~collapslble type or may be resilient.
Integral wlth the housing 12 is a han~le 20, which extends alongside the container or tube 18, but also extends slightly divergent therefrom to facilitate manipulation of the device 10 while squeezing the container or tube 1~.
In order to facilitate application of the medication, the housing 12 includes a tubular portion or passageway 22 ~hich extends angularly to the rest of the housing at an angle ranging from 20 degrees to 45 degrees from axial alignment with the container or tube 18 and, preferably, at 30 degrees. A further offset passageway 24 extends angular~y to passageway 22 and at a reverse thirty-degree angle to the axis of the container or tube ,~ ~ 2a2~2~
18 in the direction of the passageway 2Q. The angle may vary from twenty to fort~-five degrees, but the thirty-degree angle is most preferable.
A flexible tip 28 is provided at the end oE
passageway 2~ and the channel 26 for passage of medicament may taper toward the tip 28, as desired, to obtain the desired size and shape of the medicament to be applied.
As can be seen in Fig. 2, a cap 30 may be provided for the end of tip 2&, which may have a bead 32 thereon for cooperation with a bead 34 on the tip 28 so as to pro~ide a snap-fitted closure for the tip 28.
In Fig. 4, a modified form of cap uses cooperating internal threads 42 on the cap ~0 which threadedly engage threads 44 on tip 28' to form a closure for the tip 28'.
Referring now to Fig. 3, therein is shown a squeezable refillable bulb 50, which has an externally threaded neck 52 for removable securement to the housin~
12. The bulb 50 is formed of an elastic, resilient material, such as rubber or a plastic having rubber-like properties. When squeezed, the bulb 50 acts as a hand-held pump for intermittently forcing medicament to and through the tip and is restored to its original condition through an air intake 56 provided with a screen 58 and baffle 60, which permits air to cnter the air intake 56, but prevents exit of medicament. The baffle reduces the possi~ility of clogging of the air intake 56~
~ 202~2~
In use, the angular direction of the passageways and location of the tip 28 or 28' facilitates placement of the tip in its desired location, the angled passageways facilitating visibility of the oral cavity.
A suitable yield point for the gelled medicament greatly improves the effectiveness of the product used. If the yield point is too low, the product will not be as effectively retained within the subgingival poc~et or gingival margin. If the yield point is too high, then the product will be difficult to dispense through the small opening in the tip. Low thixotropy is a desirable characteristic of the medicament. The medicament undergoes extensive shear as it is forced through the small orifice in the tip. Rapid redevelopment of the solid structure will improve the retention of the product within the subgingival pockets and on the gingival mar8ins.
The gelled medicament used in the treatment of the aforementioned gum diseases may consist of suitable antibacterial agents, oxygenating agents, antibiotics, anti-inflammatory agents, anti-calculus agents, sodium bicarbonate or other materials recognized to be effective in the treatment of gum diseases. The device may also be used to treat subgingival caries and remove subgingival calculus with gelled medicaments, such as fluoride, calcium chelating and antinucleating ingredients or other suitable materials. The use of local anesthetics, such as benzocaine, may also be used to relieve tenderness of inflamed areas.
` ~` ~ 202~2~
If desired, the device may be used to deliver medicaments that do not have a yield point and have a rheology even as low as water. Medicaments with this kind of rheology are easily dispensed ~ith this device
