The method of treatment hyperesthesia hard tooth tissues

 

(57) Abstract:

The invention relates to medicine, namely to dentistry. The method of treatment is that on the wet surface of the teeth appliciruut drug film, using biopolymer medicinal adhesive film based on plasticized polyvinyl alcohol containing as the main medicinal component of sodium fluoride and chlorhexidine digluconate or benzalkonium chloride for additional antiseptic action; impose film once a day for 5-7 days. The application of this film provides a high therapeutic effect. This method eliminates unpleasant organoleptic sensations of patients and limit the food intake, and also eliminates the need for repeated visits to the clinic.

The invention relates to medicine, namely to the dentist.

There is a method of treatment of hyperesthesia of hard tissues of teeth by carrying out electrophoresis of 0.2% aqueous solution of sodium fluoride, which is introduced from the cathode in 2-3 minutes; course of treatment is 10 procedures. The disadvantages of this method is the need to use specially the I, requiring repeated visits by patient clinics.

The use of sodium fluoride is one of the most studied compounds fluorine - due to the ability of fluoride compounds to be adsorbed on the surface of the tooth and to enter into a chemical bond with crystals of hydroxyapatite. Upon substitution of the hydroxyl group formed fluorapatite is more stable connection than hydroxyapatite. When this occurs, the seal enamel and reduce its susceptibility to the influence of external factors.

One of the most widely used domestic drugs to reduce hyperesthesia is the f-containing liquids containing 2.9% of fluorine and which is the composition of natural resins viscous consistency dark yellow color. The tooth surface is rubbed with a cotton swab and put it between fluorine varnish using a cotton ball, swab or plastic spatula. Within 4-5 minutes after application ftorlaka patient should not close the mouth, and then during 12-22 hours is recommended to only eat liquid food and brush your teeth. The application was performed three times with an interval of one or two days, after 6 months the whole procedure is repeated. (L. N. Maximov, P. I. Roshchin. Medicines in the practical efficiency, unpleasant organoleptic sensations of patients and restrictions in food intake due to the peculiarities of the methodology and the need for repeated visits to the clinic.

The technical task of the present invention is to increase the effectiveness of treatment of hyperesthesia hard tissues of the tooth.

To solve the problem of reducing the increased sensitivity of the tissues of teeth - use adhesive biopolymer film based on plasticized polyvinyl alcohol made from hydrophobic and hydrophilic layers. The hydrophilic layer includes sodium fluoride and antimicrobial agent in the form of chlorhexidine digluconate or benzalkonium chloride.

Can be used in the film "diplan-dent" (company "NORD-OST", RF) TU 9391-001-292442200-98.

Example of preparation of a film for the treatment of hyperesthesia hard tissues of the tooth.

To 70 cm3solution for applying hydrophilic layer add the calculated amount of auxiliary components, stirred at 25oC until complete dissolution. Then injected 10 ml of 2% solution of chlorhexidine digluconate and 10 ml of 2% aqueous solution of sodium fluoride and again mix until dissolved; received Vomero spread over the surface and dried in a stream of inert gas at 25-30oWith up to a moisture content of 5-7%. The finished two-layer film catch a knife, gently pull it from the glass and cut the size of 50100 mm; the content of chlorhexidine and sodium fluoride ranges from 0.01 to 0.03 mg/cm2.

Indications for use of the film are diseases of hard tissue of teeth, accompanied by increased pain sensitivity: the erosion of enamel, wedge-shaped defect, abrasion and acid tissue necrosis of the tooth.

The method of use of the film strip film of a width of 5-10 mm appliciruut to wet the surface of the teeth and partly on the mucous membrane of the gingival margin 1 time per day after the evening brushing. Residual film independently dissolved in a few hours or removed mechanically during the next cleaning. The recommended duration of treatment is 5 to 7 days.

Example 1. Patient R. , 1958 R., complained of sharp pain in the area of the incisors of the upper jaw from thermal and chemical stimuli. When viewed in the cervical areas of the Central and lateral incisors of the upper jaw revealed superficial enamel defects Cup-shaped form with pigmented bottom, the processing of which a stream of air caused sharp is appliciruemah film "diplan-dent" with fluorine. In addition, the film was handed to the patient with recommendations for its independent use at home for 5 days. When viewed through 7 days after the first treatment, the patient had no complaints; pain from thermal and chemical stimuli were absent; reaction to treatment with enamel air jet was not observed.

Example 2. Patient D., 1939, R., appealed with complaints about pain in the chewing surfaces of molars and premolars when eating and brushing your teeth. Upon examination revealed intense loss of hard tissues of teeth chewing the lower jaw, the lack of enamel cusps of the molars; the surface sensing painful response to cold pronounced. Diagnosis: increased abrasion of hard tooth tissue.

After conducting a 4-day course appliqués film "diplan-dent with sodium fluoride, the patient reports no pain when eating and brushing your teeth; sensing the chewing surfaces of the teeth painlessly.

The application of this film in the proposed method leads to a high therapeutic effect. This method eliminates unpleasant organoleptic sensations of patients and constraints via hyperesthesia of hard tissues of teeth by application to the surface of the teeth means, containing fluorine compounds, characterized in that the surface of the teeth impose biopolymer adhesive film based on plasticized polyvinyl alcohol made from hydrophobic and hydrophilic layers, while the hydrophilic layer includes sodium fluoride and chlorhexidine digluconate or benzalkonium chloride; impose twice a day for 5-7 days.
