Abstract

FIELD: medicine.

SUBSTANCE: plaque, residuals of subdingival tartar and granulation tissues are removed by an erbium laser ray with 80 mJ radiating power, 8 Hz impulse frequency, λ=2.94 Hm wave length in the SSP mode.

Description

The invention relates to medicine, in particular to periodontics.

Currently, professional oral hygiene is an urgent problem, without which it is impossible to treat and prevent major dental diseases, including gingivitis and periodontitis.

The closest in technical essence and the achieved result is a method of treatment of periodontitis, based on professional cleaning, removal of dental deposits, smoothing the surface of the tooth root and closed curettage, carried out by hand tools, rotating burs and polishes (E.D. Kuchumova, Y.V. Stuf Methods of removing dental deposits by hand tools. "Scientific and Practical Journal for Dentists" Periodontics "No. 4 (29) 2003, p.51-55).

Hand tools are the standard in the treatment of periodontitis, however, they have several disadvantages: low efficiency in areas with complex anatomical relief, aggressive processing, lack of antiseptic effects, damage to orthopedic structures and restorations, the need for constant sharpening and relatively fast wear of tools, long processing time, great dependence on the degree of possession of manual skills of the doctor.

The use of a curette is traumatic for hard and soft tissues, leads to a significant removal of hard tissues, the occurrence of increased tooth sensitivity, it is necessary to change the tool depending on the relief of the treated area. After machining the root surface, the formation of dental plaque again begins. The rate of plaque formation substantially depends on the surface roughness of the tooth.

The technical result, the achievement of which the creation of this invention is directed, is to increase the effectiveness of the process of treating periodontitis by reducing the morbidity of treatment, reducing the treatment time of the surfaces of the roots of the teeth, by not depending on the degree of possession of manual skills of the doctor during treatment, and also by increasing the degree processing hard tissues and optimizing the process of periodontal tissue regeneration.

The technical result is achieved in that in the method of treatment of periodontitis, including the removal of plaque, remnants of the subgingival calculus, granulation tissues, alignment of exposed cement of the root of the tooth, it removes the plaque, remnants of the subgingival calculus and granulation tissue using an erbium laser beam with a radiation power of 80 mJ, pulse frequency 8 Hz, wavelength λ = 2.94 nm in SSP mode, sealing irregularities and gaps of damaged cement in the root of the tooth with its simultaneous sterilization is carried out by a neodymium beam of a laser in VSP mode, with a fiber diameter of 300 μm, with a radiation power of 1.0 W, a pulse frequency of 15 Hz, wavelength λ = 1064 nm, after which a closed curettage is performed with a neodymium laser beam in VSP mode, with a fiber diameter of 200 μm, at a power of radiation of 2.0 W, a pulse frequency of 20 Hz and a wavelength of λ = 1064 nm.

A method for the treatment of periodontitis is as follows. A patient diagnosed with periodontitis is removed from plaque, residual subgingival tartar and granulation tissue using an erbium laser beam in SSP mode at a radiation power of 80 mJ, a pulse frequency of 8 Hz and a wavelength of λ = 2.94 nm.

Then, irregularities and gaps of the damaged tooth root cement are sealed and, at the same time, they are sterilized with a neodymium laser beam in the VSP mode, fiber diameter 300 μm, with a radiation power of 1.0 W, a pulse frequency of 15 Hz and a wavelength of λ = 1064 nm.

A closed curettage is carried out with a neodymium laser beam in VSP mode, a fiber diameter of 200 μm, with a radiation power of 2.0 W, a pulse frequency of 20 Hz and a wavelength of λ = 1064 nm.

Example. Patient Loginova M.D., born in 1967. Diagnosis: Periodontitis chronic localized mild. Pockets in the area of the lower anterior teeth 3-3.5 mm. The supragingival tartar was removed using a universal hygienist scaler, plaque was ablated from the tooth root surface with an erbium laser beam in the SSP mode with a power of 80 mJ, wavelength λ = 2.94 nm, the root surface was aligned with a neodymium laser beam in the VSP mode, fiber diameter 300 μm, power 1.0 W, pulse frequency 15 Hz, wavelength λ = 1064 nm. Closed curettage in the region of the lower anterior teeth was performed using a neodymium laser beam in the VSP mode, a fiber diameter of 200 μm, at a power of 2.0 W, a pulse frequency of 20 Hz, and a wavelength of λ = 1064 nm. Immediately after the treatment of pain and bleeding was not noted, the gingival margin is covered with dry crusts. After 3 days: the gums are pale pink with small areas of brownish crusts along the gingival margin. After 7 days: the gum is pale pink, dense, bleeding is not observed. After 3 months: no complaints, gum pale pink, dense, no pockets. On the roentgenogram, a seal is visible along the edge of the cortical plate in the form of a clear white strip.

During experimental tests and histological studies revealed the following advantages of the proposed method for the treatment of periodontitis using combined exposure to laser beams with various exposure parameters, namely:

- improving the degree of processing of hard tissues;

- sealing of irregularities and gaps in the cement of the tooth root and sterilization of periodontal tissues;

- optimization of the periodontal tissue regeneration process:

- prevention of bleeding complications.

In the experiment, the microroughness of the cement of the root of the tooth after treatment with an erbium laser in the SSP mode at a radiation power of 80 mJ, a pulse frequency of 8 Hz, and a wavelength of λ = 2.94 was 3.128 ± 0.113 mm in 20 cases out of 25.

The microroughness after subsequent processing by a neodymium laser in VSP mode, a fiber diameter of 300 μm, with a radiation power of 1.0 W, a pulse frequency of 15 Hz and a wavelength of λ = 1064 nm was 0.644 mm ± 0.039, i.e. decreased by 5 times, in addition, there was a sealing of microroughnesses (gaps) of the cement of the root of the tooth.

The analysis of the prior art by the applicants, including a search by patent and scientific and technical sources of information and identification of sources containing information about analogues of the claimed invention, allowed us to establish that the applicants did not find an analogue characterized by features identical (identical) to all essential features of the claimed invention.

The determination from the list of analogues of the closest technical solution (prototype) made it possible to identify a set of essential distinguishing features in relation to the arranged technical result in the claimed method of treatment of periodontitis, set forth in the claims.

Therefore, the claimed invention meets the criterion of "novelty."

The claimed technical solution does not follow for a specialist explicitly from the prior art, because to verify the conformity of the proposed method, the applicant conducted an additional search for known solutions, as a result of which no signs were found that coincided with the distinctive signs of the method of treatment of periodontitis from the prototype.

Therefore, the claimed invention meets the criterion of "inventive step".

The criterion of "industrial applicability" is confirmed by the fact that the proposed method for the treatment of periodontitis can be effectively used in the practice of treating widespread periodontal diseases and treating gingivitis.
