Definitions

• a composition for admixture with water cooling sprays in dental treatment processes is provided.
• This invention relates to a method for alleviating pain in dental treatment processes and for preventing cloud ⁇ ing of a dental mirror by water droplets when cooling the mouth of a patient with the aid of a water spray, and also to a composition for admixture with such spray water during dental treatment.
• a composition which contains one or more surfactants so as to reduce surface tension and wet the surface to prevent fogging there is used.
• the sur ⁇ factant or surfactants is, or are, added directly to the water used for cooling purposes. Because the water is delivered under pressure, it will tend to foam. This foaming tendency is counteracted, however, by the add ⁇ ition of a foam retarding agent.
• This enables sur ⁇ factants to be added directly to the water, without needing to provide separate arrangements, as distinct from the case in the solution proposed in the afore mentioned US Patent Specification 3.755.903.
• the continual supply of wetting agent enables work to be carried without interruption, e.g. stopping to wipe dry the mirror, this advantage being beneficial from the aspect of safety and also from the aspect time.
• inventive composition Another advantage afforded by the inventive composition is that the supply of surfactant solution will keep the instruments used clean and that cavities and the sur ⁇ faces of teeth are also made cleaner during treatment, due to the washing effect of the solution. It has been found that when using the inventive composition, no additional cleansing or washing liquid, such as type "Tubulicid", need be used to clean cavities and tooth- surfaces after treatment with dental instruments.
• surfactant may be used and the type of surfactant selected and the surfactant mixture is deter ⁇ mined in accordance with a number of desired, different qualities or properties, such as
• present day surfactants are divided into different groups, such as soaps, alkane sulphonates, olefin sulphonates, ester sulphonates, alkylaryl sulph ⁇ onates, particularly alkylbenzene sulphonates of the type dodecyl benzene sulphonate and alkyl naphthalene sulphonates, alkyl sulphates, ether sulphates, fatty alcohol (ether) sulphates; cationic surfactants such as straight chain and cyclic ammonium compounds, those compounds earlier referred to as invert soaps, benzal- konium chloride and other quaternary ammonium salts, amine salts, pyridiniura salts; non-ionic surfactants such as polyethers, particularly alkylphenyl polyglycol ethers etc., products obtained from the ethoxylation of fatty acids, fatty acid amides, fatty amines, and fatty
• the inventive composition includes one or more surfactants, the choice of surfactant being contingent on the aforesaid desired properties.
• the upper limit of the quantity of surfactant used is determined by the taste of the ready-to-use solution; it will be under ⁇ stood that the taste should not be excessively bitter. Many surfactants have a markedly bitter taste.
• the lower limit is determined by the lowest level at which fogging or the formation of water droplets on the mirror surface will not take place and at which wetting of the surface is achieved such as to provide good vision through the mirror.
• the read-to-use solution may contain surfactant in quantities of, for instance, 0.02-0.5 percent by volume, preferably 0.04-0.25 percent by volume, and particularly 0.06-0.20 percent by volume.
• the inventive composition also contains an anti-foaming agent which is added in quantities to extinguish foam generated by the surfactant solution or to retard the. " foam so that it will not obstruct the view in the mir- ror.
• the anti-foam agent, or foam retarding agent may be added in quantities of, for instance, 0.002-0.125 per ⁇ cent by weight, suitably 0.005-0.065 percent by weight, preferably 0.08-0.050 percent by weight.
• the aforesaid properties or qualities recited with respect to the surfactant used will naturally also apply to the foam retarding agent with regard to human toxic and dermatological effects, taste, foam retarding effi ⁇ ciency, water solubility, its lenient effect on sub- stances in the oral cavity, such as saliva, tooth fill ⁇ ings, tooth enamel, etc..
• the foam retarding agent used will also preferably be biodegradable.
• the inventive composition is produced in the form of a concentration containing surfactant, foam retarding agent and water, preferably in the form of "Aqua puri- ficata".
• the amounts in which these substances are present in the concentrate solution are, in turn, deter ⁇ mined by the desired concentration of the solution to be used, which solution must be capable of effectively wetting the mirror surface while at the same time the -taste of the solution must be acceptable to the patient. Consequently, it is not possible to state generally specific concentrations of the substances in the con- centrate solution, but that these quantities are deter ⁇ mined in dependence on the substances selected and their properties, and the solution is therefore composed so that there is obtained a concentrated solution which, in turn, can be readily dispensed, e.g. by measuring suit- able quantities in a measuring glass when mixing the solution to be used.
• the concentration of the ready-for-use solution will thus depend on the aforesaid factors and can therefore only be established by testing for taste and wetting effect with each individual mixture.
• the inventive composition may also include other, known additives for achieving special effects, such as anti- bacterial additives, acidifying agents, flavouring agents and the like.
• the composiion may also be admixed with chlorhexidine as an antibacterial addition, in an amount of about 1 percent by volume, in combination with "polysorbatu " in an amount of 0.2 percent by volume, a wetting agent which is necessary for bringing the chlorhexidine into mixture with remaining components without forming precipitates, and/or citric acid in an amount of 0.1 percent by weight as an acidifier, and/or a flavouring agent, for instance menthol,in an amount of 0.05 percent by weight, and/or a preservative, e.g. "Metagin" in an amount of about 0.1 percent by volume.
• citric acid added to acidify the solution will also decrease the tendency of lime deposits to form on the walls of the spray passages in the nozzle used.
• the inv ⁇ entive composition has been used as an additive to spray water used in ultrasonic depuration treatment, i.e. the removal of plaque by ultrasonic sound.
• ultrasonic depuration treatment i.e. the removal of plaque by ultrasonic sound.
• Still another series of tests was carried out by a third dentist. This test was carried out with a starting point from patients who were sensitive to ultrasonic depur ⁇ ation. 17 patients were tested with respect to the difference in the pain experienced or felt when two different cooling liquids were used, namely a test liquid comprising 25 % by volume of the inventive com- position and 75 % water, and a control liquid comprising solely water. Only vital teeth, with no large fillings or crowns, jackets, were treated in this test. The test area was chosen at random, on both the right and the left sides of the jaw. Of these 17 patients, 8 con- sidered there to be no difference in the sensation of pain, whereas eight patients experienced far less pain sensation. One patient felt the pain to be worse.
• the inventive composition was administered with the aid of a stainless container, volume 4.5 litres, and com ⁇ pressed air, about 2g atm. was injected into the con ⁇ tainer filled with the ready-for-use solution.
• the container included an outlet which was connected to the water supply of a turbine drilling machine, a plaque removal device and a blasting device. It was necessary to refill the container twice weekly, in those instances when patient attendance was normal. In this way there was maintained a constant concentration and dosage of the inventive composition.
