Definitions

• This invention relates to a means for the application of various substances or medicaments in therapeutics, and more especially in the treatment of teeth.
• Teeth may be treated for numerous reasons-as, for example, in active disease, for the prevention of disease, or, for purposes of gaining immunity to disease, and, in the treatment, various materials or drugs may be employed. Also, very frequently it is desirable, in dental practice, to apply medicaments not only to diseased areas, such as the surface of cavities, etc., but also to entirely sound portions of the teeth.
• the procedure is generally to dry the surfaces tobe treated with the patients mouth propped open, after which the medicament is applied to a portion of the tooth or to the whole tooth.
• the patient is asked to keep his mouth open for as long aspossible to allow the solution to act.
• Another object of this invention is to provide a means for sealing the medicament on a specific tooth or area on a tooth so that it cannot be interfered with by saliva, air, food, or other substances common to the oral cavity.
• Still another object of this invention is to provide a means for limiting medication to only a given spot or area so that the danger of a strong drugs spreading where it is not needed and can cause irritation, is eliminated.
• This device contemplates sealing the medicament against the tooth by means of a thin sheath of cellulosic film or the like, one surface of which has been coated with a medicated adhesive. Physically, this tape resembles what is commonly called Scotch tape.
• Figure l is an enlarged view of the front or labial surface of an upper central incisor.
• Figure 2 is a sectional View of the same tooth made along the lines A-A of Figure 1.
• Figure 3 is also a sectional view of an upper central incisor.
• Figure 4 is an enlarged view of the front or labial surface of an upper left central incisor.
• Figure 5 is. also an. enlarged view of the front or labial surface of an upper left central incisor.
• Figure 6 is an enlarged view of the buccal or cheek surface of a lower first molar.
• Figure 7 is a diagrammatic cross sectional view of the construction of the medicated tape.
• Figure 8 is diagrammatic cross sectional view of an: other modification of the medicated tape- In Figure 7 is illustrated the novelconstruction of the medicament-carrying means. It is. a flat tape of several layers.
• At 15 is an outer layer or backing.
• a medicated adhesive layer which may be placed directly on the backing, as illustrated in Figure 8,01, on a primer coat 16, which is used to advantage Where great strength between the medicated adhesive layer and backing is required.
• the primer layer is composed of two parts rosin, two parts crepe rubber, dissolved in about thirty-two parts ben- 201, by weight. This layer should be applied very thin and. allowed to dry before adding the medicated adhesive layer 17.
• the outer layer 15, or backing to which the medicated adhesive coating is united be transparent.
• the medicated adhesive coat, itself is also generally somewhat transparent, thus lending an appearance, of transparency or unnoticeability to the entire application rendering the teeth to which an. application has been made,. not conspicuous.
• the backing 15 is generally a non-fibrous fi-lm of gelatinized ceilul'osic material, such as regenerated cellulose, cellulose esters, cellulose ethers, or composites of such materials as, for example, a film of regenerated cellulose.
• ceilul'osic material such as regenerated cellulose, cellulose esters, cellulose ethers, or composites of such materials as, for example, a film of regenerated cellulose.
• backings can be utilized comprised of materialsother than gelatinized cellulosic materials and which are either non-fibrous or are coated with non-fibrous films, preferably Waterproof, composed of cellulosic or other suitable material, including varnishes, lacquers, etc.
• sheets of such' film material are provided with coatings of normally tacky and pressure-sensitive medicated adhesive firmly united here to.
• normally tacky and pressure-sensitive it is meant that under ordinary atmospheric conditions the medicated adhesive is stable in a condition such that it does not needto be activated by solvents or heat or otherwise prepared in order to secure good adherence to surfaces against which the medicated adhesive coating, with its backing, maybe pressed when used.
• the medicated adhesive may be made in a number of ways. There are quite a few formulas for adhesive and V a any number of them can be compatible with medication according to the teachings of this invention.
• a rubber compound and a tackiness-augmented agent in the form of a synthetic resin are used together with the medicament, sodium fluoride.
• Proportions suitable for ordinary temperate climates may comprise:
• the cumarone gum or resin is an artificial resinous material coming under the group name of cumarone and indene resins, which is the polymerization product of coal tar derivatives.
• the above ingredients are compounded on a rubber rolling mill to a plastic condition and then cut to desired body or consistency, using a rubber solvent such as benzol or a petroleum solvent, such as high test gasoline.
• a rubber solvent such as benzol or a petroleum solvent, such as high test gasoline.
• low melting point natural resin may be employed, such as Burgundy pitch or pine oil foots. Burgundy pitch is soluble in both alcohol and benzol.
• the sodium fluoride may be varied from of 1% to 18% by weight, depending on where it is to be used in the mouth and on whom it is to be used. In the case of children where there is a likelihood of a childs dislodging the medicated tape and perhaps even swallowing it during sleep, very low percentages of concentration are indicated. Where it is to be applied as the base in a cavity or in a position where it cannot come loose, the percentage can be increased for greater effectiveness.
• Sodium fluoride is used to illustrate this invention because it has been found that the application of this medicament against the tooth has the effect of greatly increasin gjhe tooths resistance to decay.
• this sodium fluoride medicated tape enables the dentist to place sodium fluoride for long periods where it is needed to obtain significant results.
• sodium fluoride has been here illustrated as a medicament for immunizing teeth against caries, it is clearly understood that any medicament may be used for this purpose-stannous fluoride, calcium fluoride (fluorspar), cryolite, which is a double fluoride of sodium and aluminum, or zinc fluoride.
• various bleaching agents such as potassium chlorate
• a central incisor has a medicated adhesive strip 4 attached to the labial surface 2 of the tooth.
• the reason for placing a patch of strip, as illustrated, may be that the dentist has noted incipient decay, and, instead of cutting away a large portion of the tooth, he has decided to try to immunize the tooth against further decay.
• an immunity thereby results, which not only is present at the area of the patch, but may extend to the entire tooth.
• the patch should be permitted to stay on the tooth for a minimum of three or four days, if possible.
• Figure 2 is a cross section of the same tooth along the lines AA of Figure 1.
• At 4 is the medicated adhesive tape, at 2 is the crown of the tooth, and 3 is the root.
• the patch 4 has been made to cover the labial surface of the tooth, excepting that it was desired that the tape not touch the area 8, so a small piece of cotton was inserted underneath the tape at the point 8 and this part of the tooth consequently is not in contact with the medicament.
• a patch 4 has been placed over the area '7 of the root 3 and the gingival area 6 of the labial surface 2.
• the patch of this type is especially valuable in treating sensitive dentine and enamel which frequently exists or occurs where gums recede.
• the preferred medicament for sensitivity is a 5% sodium fluoride adhesive mixture or a 1% Zinc chloride adhesive mixture. There are, of course, other medicaments, equally eflicacious which can be substituted.
• the medicated adhesive band completely encircles the crown 18 of the tooth and laps over at the point 5 on the labial surface 2.
• This treatment is used to prepare a tooth for orthodontia bands or where decay or white spots may be forming on numerous places in the crown.
• sodium fluoride is the preferred medicament in the adhesive.
• Figure 6 is a lower first molar where the medicated adhesive tape 4 covers the gingival portion 12 of the crown 9 and the gingival portion 11 of the root 10.
• the medicament in the adhesive tape of this nature would be indicated by what condition was being treated.
• the tooth is While the surface is dry, the medicated tape is applied with sutficient pressure to seal the tape on the tooth surface.
• the tape After the tape has served its purpose, it is peeled off by engaging a corner with a sharp instrument or the finger nail. Should any of the adhesive adhere to the tooth structure it can be removed with any organic solvent such as zylol, benzine, acetone, alcohol-or a dry piece of cotton, where no solvent is available, will suffice through mere friction.
• organic solvent such as zylol, benzine, acetone, alcohol-or a dry piece of cotton, where no solvent is available, will suffice through mere friction.
• a device for sealing a medicament on a tooth surface so that it cannot be interfered with by saliva, air, food, or other substances common to the oral cavity comprising an easily removable inconspicuous laminated patch of tooth size, said patch consisting of an outer layer in the form of a thin sheath of transparent, water insoluble cellulosic film and a transparent inner layer in the form of a pressure sensitive adhesive containing a fluoride salt, in the amount of /10 of 1% to 18% by weight.
• a device as in claim 1 in which a primer layer is 5 interposed between the outer and inner layers, said primer layer being composed of two parts rosin, two parts crepe rubber, dissolved in about 32 parts benzol by weight.
• a method of preventing tooth decay which comprises sealing a medicament against a tooth by means of a patch of tooth size, said patch comprising a thin sheath of cellulosic film, one surface of which has been coated with a pressure sensitive medicated adhesive containing a fluoride salt, in the amount of A of 1% to 18% by weight, allowing the patch to remain upon the tooth for a desired time interval, and then peeling the patch 011?.
