Description

METHOD AND COMPOSITION FOR TREATMENT OF PERIODONTAL DISEASE
BACKGROUND OF THE INVENTION
Field of the Invention
The present invention relates to a method and composition for treatment of periodontal disease and, more particularly, to a composition suitable for topical application to prevent and treat periodontitis.
Description of the Prior Art
Periodontal disease is the major cause of tooth loss in adults. The periodontium is subject to inflammation for many reasons, primary among them being the accumulation of plaque deposits under and above the gumline. These calcareous deposits of organic and mineral matter, which consist of microbial colonies growing in carbohydrate residues (from food) , attach themselves to tooth surfaces and can, over time, calcify into tartar. This hard, mineralized substance adheres tenaciously to the teeth and, when under the gumline, causes inflammation of the periodontium. Other causes of periodontitis can include malocclusion, food impaction and mouth breathing.
Periodontitis can cause the gumline to retract due to supporting bone loss and the gums to bleed, and eventually, if not treated, can result in tooth loss. Until now, the only known treatment for periodontitis, outside of taking preventive measures to keep it from developing in the first place, was surgery. The accepted surgical procedure involves removing the inflamed gum tissue, which is expensive and requires a long and painful recovery.
There have been various attempts at treating periodontal disease without such surgical intervention. The best such attempt to date resides in an oral rinse sold by Procter & Gamble under the name Peridex®. The chemistry of this product is described in the 1988 Phvsicans' Desk Reference at pages 1648-49. Unfortunately, Peridex® rinse has not proved as efficacious against periodontal disease as might be desired and exhibits unwanted side effects, such as staining of tooth surfaces.
The following patents also disclose oral treatment agents, but none is believed to represent a substitute for surgical intervention as a treatment for periodontal disease:

Of interest with regard to the present invention are U.S. Patent 4,486,404 which, in Example 5, discloses a toothpaste containing chlorhexidine gluconate and allantoin, U.S. Patents 3,937,807 and 4,051,234, which disclose mouthwashes with gluconates and anti-stain agents, and U.S. Patent 4,569,837, which discloses the use of chlorhexidine gluconate and aspirin to treat periodontal disease. SUMMARY OF THE INVENTION It is an object of the present invention to provide a composition and method for treating Periodontitis I without costly and painful surgical intervention.
In accordance with one aspect of the invention, a composition suitable for treating periodontitis comprises an aqueous solution of an antimicrobial agent with bacteriacidal activity, an agent with therapeutic action against skin ulcers, an analgesic, a stain remover and, if desired, suitable wetting agents, emulsifiers, dispersants, buffers stabilizers, preservatives, flavoring and coloring.
In accordance with another aspect of the invention, the composition is used in a treatment method which comprises the steps of topically applying the composition to inflamed periodontium.
DESCRIPTION OF PREFERRED EMBODIMENTS In a preferred embodiment of the invention the various components of the composition of the present invention are present in an aqueous carrier of sterile distilled water, glycerine and ethanol. The glycerine provides the composition with the desired feel and texture and the ethanol acts as an antiseptic.
To this water-glycerine-ethanol carrier is added (1) chlorhexidine gluconate (0.12% solution), C3H5Cl2N10O14 (Merck Index 2057) , as an antimicrobial agent with bacteriacidal action, (2) allantoin, or (2,5-dioxo-4- imidazolidinyl)urea (Merck Index 242) as an agent that exhibits therapeutic action against skin ulcers, (3) sodium salicylate, or 2-hydroxybenzoic acid monosodium salt (Merck Index 8515) , as an analgesic, and (4) sodium bicarbonate (Merck Index 8414) as a stain remover, along with wetting agents, preservatives, emulsifiers, dispersants, buffers stabilizers, flavoring and coloring, as desired. (All references herein to the Merck Index refer to the 1983 edition.)
In particularly preferred embodiment, the above ingredients are provided in the following proportions:
TABLE 1
Sterile Water 70.77%
Glycerine (MI 4347) 11.15%
Ethanol (MI 212) 7.50% Polysorbate 80 (as an emulsifier and dispersant; MI 7455) 4.20% Chlorhexidine gluconate (0.12% sol.) (MI 2057) 3.50% Sodium bicarbonate (as a stain remover; MI 8414) 0.50% Sodium lauryl sulfate (as a wetting agent; MI 8474) 0.50%
Vanilla (as flavoring; MI 9732) 0.60%
Saccharine (as flavoring; MI 8170) 0.20%
Sodium salicylate (MI 8515) 0.15%
Allantoin (MI 242) 0.638% Sodium benzoate (as a preservative;
MI 8413) 0.10% Xanthan gum (as a stabilizer and e ulsifier; MI 9868) 0.10%
Sodium borate (as a buffer; MI 8421) 0.085%
F.D.& C. Blue (as coloring) 0.005%
F.D.& C. Red 40 (as coloring) 0.002%
[Notes to Table 1 - (1) All proportions of the above ingredients are v/v; (2) "MI" refers to the Merck Index]
The above composition is prepared by first measuring an appropriate quantity of sterile distilled water; for example, lOOOcc of the composition is to be prepared, 101 . lc . of water are used. The remaining ingredients are added in the order listed in Table 1, with each ingredient being thoroughly mixed by gently stirring the composition before the next ingredient is added.
A clinical test involving 30 people was performed using a composition similar to that set out above, except for using 72.77% sterile water, 8.00% ethanol, 1.50% chlorhexidine gluconate (0.12% solution) and 0.138% allantoin. The subjects were chosen because all exhibited, periodontal pockets up to 8mm or 9mm deep. Prior to beginning the treatment regimen, all 30 subjects agreed not to brush or floss their teeth for one week. Then, 15 of the subjects rinsed their mouths three times a day with 1.0 cc of the above composition 30 seconds before brushing and 15 rinsed their mouths three times a day with an equal amount of a colored sugar-water placebo 30 seconds before brushing. The subjects did not know whether they were using the inventive composition or the placebo.
Once a week the teeth of each subject were checked for the presence of plaque using a commercially available plaque- disclosing solution, Superdent® disclosing solution concentrate, made by Rugby Laboratories, Inc., of Rockville Centre, Long Island, NY 11570. All subjects using the inventive composition showed little or no plaque accumulation, while there was such plaque accumulation on the teeth of the subjects using the placebo.
The test procedures were continued for 12 weeks, and the subjects' conditions were measured in accordance with the Simplified Oral Hygiene Index (OHI-S) described in Orban's Periodontics (3rd Ed. 1968), The C.V. Mosby Co., St. Louis, MO, at page 134. It was found that the average OHI-S for the subjects on the placebo went from 8mm to 9mm periodontal pocket depth to 6mm to 8mm pocket depth during the 12 week test, while that for the subjects using the inventive composition improved from 8mm" to 9mm periodontal pocket depth to 2mm or 3mm pocket depth, which is considered within normal range.
It is expected that repeated use of the inventive solution will reduce inflammation, stop bleeding and keratenize damaged periodontal tissue.
Of course, variations of the above preferred embodiment are possible within the scope of the present invention, such as varying the proportions of the chlorhexidine gluconate, allantoin and sodium salicylate within ranges that provide efficacious results. It is intended by the claims appended below to include all such variations within the present invention.
