Definitions

• the present invention concerns a mouthwash solution intended to prevent enrichment of heavy metals in the oral cavity on mucuous membranes and dental surfaces.
• corrective dental care metallic materials are used in rather great profusion, such as tooth fillings and crown materials; the number of different materials is estimated.to be more than one hundred. Usually these materials are composed of four or five different metals and compounds thereof. 5
• amalgam filling which is typically prepared of mercury (contribution about 45-55%) and of a premix, which typically has had the composition: Ag 67-70%, Sn 25- 29%, Cu 0-5%, Zn 0-2%.
• amalgam fillings copper 0 tends, owing to price considerations, to replace silver, its quantity rising even up to 30%.
• composition of the materials which are used and the contribution of base metals vary considerably both from manufacturer to manu ⁇ facturer and in accordance with the requirements imposed on the 5 prosthesis.
• the problem in dental care of the kind Just described have been allergic reactions of patients, especially in risk groups like asthmatics, who on the whole are disposed to allergic reactions.
• the cause responsible for these reactions is the dissolving of heavy metals in the mouth from dental care materials. These heavy metal effusions tend to become enriched and to accumulate in the oral cavity on dental surfaces, darkening them, and particularly on mucuous membranes.
• the object of the present invention is to prophylactically prevent allergic reactions started by heavy metals and the darkening of dental surfaces, by preventing enrichment and accumulation of heavy metal ions in the oral cavity.
• the mouthwash solution of the invention is, in order to achieve this, characterized in that it contains water-soluble alkali metal or earth alkali metal salt or salts, in particular Na, K, Mg or Ca salt, or their combination salt or a mixture thereof, of an amino- (carboxylic) acid or acids forming with heavy metal ions stable,
• the mouthwash solution of the invention is used by washing the oral cavity frequently enough with a solution containing an appropriate
• iminodiacetic acid IDA
• nitrilotriacetic acid NIA
• ITA aminotriacetic acid
• EDTA ethylenediaminetetraacetic acid
• DETA diethylenetriaminepenta- acetic acid
• HEDTA 2-hydroxyethylethylenediaminetriacetic acid
• amino(carboxylic) acids which are important as regards usability are suitable for use towards the purpose of the present invention in the form of a solution in which they occur as alkali or earth alkali salts or complex salts thereof, e.g. 2Na-Ca-EDTA.
• the acidity of the solution should be compatible with oral environment, neutralizing being most advantageously effected with NaOH.
• the solution will contain NA-Ca salt of EDTA when neutralizing the Ca ⁇ -EDTA solution with NaOH. A substantial part is present in the 2Na-Ca-EDTA form.
• Table 1 A typical picture of the properties of aminoCcarboxylic) acids is given by Table 1.
• Fig. 1 presents the contributions of the salts of EDTA at different pH levels.
• a complete ten units bridge was made by private dentist in the lower jaw from C-gold casting and this was tolerated well. Immediately after this, another ten units bridge was constructed in upper jaw from metal-ceramics. Soon after the insertion severe pains and smarting with descripted symptoms of the head region began. Several root canal treatments and paradental operations were performed by specialists without relief.
• a 5 % Ca-Na-2-EDTA in water solution was introduced for differential diagnostics. She rinsed her mouth twice daily by 10 ml of solution for two minutes. After spitting out she washed her mouth by tap water. Within three days the pain and smarting symptoms disappeared. Within three days the pain and smarting symptoms disappeared. After 3 months, August 1986 the blood controls showed normalization of eosinofiles from 525 to 194 and the differential count of leucosytes from 0.13 to 0.09 according to the eosinofiles. In a second control after three more months the eosinofile count of leukosytes had gone down to 0.06 and the blood eosinofiles were still at 194.
• the upper bridge was taken off and constructed again of a traditional C-gold alloy. She felt well with this material.
• the composition of the ceramic metal was analyzed at the Technical University of Helsinki by an Energy Dispersive Roentgen Spectrophotometry with a semikvantitative result of the non casted alloy containing 4.8% tin and the casted and oxidated alloy containing site dependent variations of great amounts of tin.
• the ceramic showed to contain 8-10% tin, the richer sites being on the colored cervical areas, where the mixture of metal oxides was used as characterization.
• the ceramic contained maximum 1% nickel on some points of the surface.
• the content of copper was varying between 1-3%.
• a metal antagonist therapy by chelating mouth rinse was performed by twice a day rinsing. This preparate calcium saturated Ca-Na-2-EDTA solution with no activity to calcium ions. After the first week of treatment the gingival smarting disappeared, patient had no fever and felt well. Mouthrinsing was performed for two months. No aftous attacks or other symptoms have appeared. Patient's symptoms are concluded to be connected to the silver amalgam fillings or other irritation of metallic nature.
