Abstract

The device for vacuum-jet irrigation of the root canals of the teeth is intended for use in dentistry. It is made in the form of two subsystems, one of which feeds the drug solution into the cavity of the root canal of the tooth and contains a needle, which is connected by hoses to the electromagnetic valve, the container with the drug solution, an additional electromagnetic valve and a vacuum source. The second subsystem is designed for vacuum suction and contains a needle, which is connected by hoses to a receiving vessel and a vacuum aspirator. The apparatus contains a nozzle consisting of sterile needles of the subsystems, welded together at the base and hermetically fixed in a conical rubber seal, on the upper edge of which a correction mass is previously applied. The use of a device for vacuum-jet irrigation of the root canals of the teeth will improve the quality of cleaning, removing the contents of the canal and drying.

Description

корневого канала, а вторую соединенную с приемной емкостью устанавливают на уровне коронковой части, герметично закрепляют их в зубе посредством пластичной массы, обеспечивают одновременную эвакуацию гнойно-некротического содержимого и удаление отработанного раствора, сушат вакуумом, потом пломбируют корневой канал любым известным из уровня техники методом, при этом вначале его пломбирование производят под вакуумом (патент RU на изобретение №2361543).The utility model relates to medicine, namely dentistry. There is a method of treating periodontitis with an apparatus for endocanal treatment of endodontic cavities, which consists in trepanation of a tooth, removal of purulent-necrotic contents and spent drug solution by vacuum, drying by vacuum and filling. After processing the cavity, removing the decay of the pulp, instrumental and antiseptic treatment of the canal, the canal is washed with a vacuum method of limited processing (VMOO), in which one needle of the apparatus, connected through a hose to the receiving capacity, is inserted to the apical opening, and the second at the level of the crown , to which a special container with a piston filled with a drug solution is attached, provide simultaneous evacuation of purulent-necrotic contents and removal of spent solution pa. Then the root canal and the apapical region are washed with a vacuum-jet method (HSR), in which one needle of the device, connected through a hose to a container with a medicinal solution, is inserted into

the root canal, and the second one connected to the receiving capacity is installed at the level of the crown part, tightly fix them in the tooth by means of plastic mass, provide simultaneous evacuation of purulent-necrotic contents and removal of the spent solution, dried by vacuum, then the root canal is filled with any method known from the prior art, at the same time, its filling is carried out under vacuum (RU patent for invention No. 2361543).

The disadvantages of the method are the insufficient extraction of the contents of the root canal, the duration of the preparation of the instrument and the VMOO and HSR.

The closest is a method of treating complicated forms of caries, which consists in trepanation of the tooth, instrumental treatment of the carious cavity of the tooth, removal of pulp decay, washing with a medicinal solution, removal of purulent-necrotic contents and spent medicinal solution, drying and filling using an apparatus containing needles, a container with drug solution, solenoid valve, receiving vessel, vacuum aspirator, interconnected by hoses. After instrumental processing of the tooth cavity with an apparatus made in the form of two subsystems, one of which contains a needle, which is connected by hoses to an electromagnetic valve and a container with a medicinal solution, the second subsystem contains a needle, which is connected by hoses to a receiving vessel and a vacuum aspirator, perform antiseptic treatment by water hammer by alternately entering into the tooth cavity the flow of the drug solution and atmospheric air through the nozzle, which is placed in the tooth cavity, consisting of sterile needles of subsystems, welded together at the base and hermetically fixed in a conical rubber seal, on the upper edge of which a correction mass is previously applied (patent RU for invention No. 2454199).

The disadvantage of this method is the insufficient exposure to vacuum for drying and extraction of the drug from the deep layers of damaged tooth tissue and periodontal.

To improve the quality of cleaning, removing the contents of the canal and drying, a device is proposed for vacuum-jet irrigation of the root canals of the teeth made in the form of two subsystems, one of which contains a needle that is connected by hoses to an electromagnetic valve, a container with a drug solution, an additional electromagnetic valve and a vacuum aspirator , the second subsystem contains a needle, which is connected by hoses to a receiving vessel and a vacuum aspirator, the apparatus contains a nozzle consisting of sterile needles by soldered together at the base and hermetically fixed in the rubber conical seal, the upper edge of which is pre-coated correcting mass.

In FIG. 1. The apparatus for vacuum-jet irrigation of root canals is well-known.

The apparatus contains a nozzle 3, consisting of sterile injection needles 1 and 2, which are soldered together at the base and hermetically fixed in a cone-shaped rubber seal 12, along the upper edge of the surface of which a corrective mass 13 is applied, which ensures sealing of the treated cavity. The first subsystem contains a needle 1, which is connected by a hose 4 to a solenoid valve 8 and a hose 6 with a capacity of 9 with a drug solution, a hose 17 with a solenoid valve 14 and a hose 15 with a vacuum aspirator 16 (type OH-10 or ALP-02). The second subsystem contains a needle 2, which is connected by a hose 5 to a receiving vessel 10 and a hose 7 with a vacuum aspirator 11 (type OH-10 or ALP-02), creating a vacuum of up to 1.0 MPa.

Apparatus for vacuum jet irrigation of the root canals of the teeth works as follows.

Tooth trepanation is carried out by the usual method, while the drill processes and forms the cavity, and then, using the “endodontics set”, the decay of the pulp is removed and the canal is instrumentally and medically treated. For the treatment of acute periodontitis in the stage of exudation and chronic periodontitis in the acute stage, the apical opening is opened. Only the appearance of pus or exudate from the canal can serve as an indicator that the apical aperture has been opened. A corrective mass 13 is applied along the upper edge of the rubber seal 12 and the nozzle 3 is placed in the channel. The mass hardens and provides a seal. Turn on the vacuum suction device 11, a vacuum is created in the tooth cavity. The drug is treated with a medicinal solution, which from the vessel 9 with the valve 8 turned on and the valve 14 turned off comes from the container 9 with the drug solution due to the pressure difference, atmospheric pressure is created due to the free flow of air through the valve 14 into the vessel 9. The drug solution enters the tooth cavity through the hose 6 to the electromagnetic valve 8, through the hose 4 to the needle 1 into the tooth cavity and washes pus, necrotic tissue, shavings after processing the canal with endodontic instruments. The spent solution through the needle 2, the hose 5 is removed into the receiving vessel 10. The electromagnetic valve 8 is turned off. There is a supply of atmospheric air without pressure through the hose 4 to the needle 1. After some time, turn on the electromagnetic valve 8, there is a supply of the drug solution followed by an air plug, which is pumped out by vacuum through the needle 2. At this time, the drug solution, accelerating through the hose 4, through the needle 1 enters the endodontic cavity, the effect of water hammer is formed. Alternately turning the solenoid valve 8 on and off, they alternate the supply of atmospheric air and the drug solution, which makes it possible to obtain the effect of a regular hydraulic shock, thereby ensuring maximum purification of the treated cavity. For final cleaning and drying of the treated cavities include solenoid valves 8 and 14 and vacuum aspirators 11 and 16.

The use of a device for vacuum-jet irrigation of the root canals of the teeth will improve the quality of cleaning, removing the contents of the canal and drying.
