FIELD: medicine.
SUBSTANCE: invention refers to medicine, namely to dentistry. A formulation for retrograde filling of root canals contains calcium oxide, aluminium oxide and silicone oxide, each of which is prepared by separate baking, processing and functional additives, and an X-ray contrast extender - zirconium oxide. The processing additive contains plasticising and water-retaining ingredients in the form of compounds of cellulose and/or its esters and/or polysorbates, as well as whitening inert ingredients in the form of titanium dioxide. As the functional additive, the formulation contains bactericidal ingredients of dioxidine, and/or metronidazole, and/or silver, and/or copper-calcium hydroxide, and anti-inflammatory ingredients in the form of glucocorticosteroids specified in hydrocortisone acetate and/or dexamethasone. The formulation can additionally contain calcium salts.
EFFECT: combination of the ingredients of the formulation in certain quantitative content provides a high prolonged alkalinity of the material of approximately pH 12, a flow characteristic of the material of 25-26 mm used to fill the root canal tightly, a setting time of the material within 10-20 minutes controlled by a dentist in the mouth cavity, an after-setting higher compression strength of not less than 40 MPa, a lower solubility of the material of no more than 1,5% and a high radio density of the material.
