The study was conducted on 21 teeth removed for various medical indications, with a concomitant diagnosis \"dental caries\". After mechanical treatment, the cavities were washed with saline solution, then CCH paste was placed on the cavity floor, covered with aluminum foil, drained and isolated with temporary fillings. To maintain the osmotic balance, the teeth were placed in a laboratory model: a plastic bath with saline solution and a melamine sponge, for a period of 1, 14 and 30 days. Then the longitudinal teeth sections were prepared for the electron microscopic examination. \u0000Results. During the CCH galvanophoresis, the dentine impregnation with copper nanoparticles in the area of cavity floor occurred already during the first day of the procedure. The penetration depth reached 10.1 microns. The maximum depth of penetration of particles into the dentin (up to 30 microns) was detected after the 30-days-galvanophoresis. The maximum values of the diffusion coefficient and its velocity were recorded after the first day. With an increase in the time of galvanophoresis to 14 and 30 days, these indicators decreased. \u0000Conclusion. The described method may be used as an option of choice for the prevention of recurrent dental caries, especially in the presence of deep cavities.","PeriodicalId":183034,"journal":{"name":"Aspirantskiy Vestnik Povolzhiya","volume":"32 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"126550979","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The material for the study was licorice herb harvested in Alekseevka settlement of the Samara Region (2021), Tatarskaya Kargala village of Sakmarskiy area of the Orenburg Region (2017), Derzhavinsk city of the Republic of Kazakhstan (2018), Bol'shaya Chernigovka village of Bol'shchernigovsk area of the Samara Region (2019), and a commercial sample of licorice root raw material from AO \"Krasnogorskleksredstva\". In addition, the reference standards (RS) were used: pinostrobin, licuraside, quercetin, rutin, luteolin and glycyram. The authenticity was determined by the thin layer chromatography (qualitative analysis). For the quantitative analysis, we used the differential spectrophotometry, conducted in accordance with Pharmacopoeial monograph 1.2.1.1.0003.15 \"Spectrophotometry in ultraviolet and visible spectra\". The spectral characteristics of water-alcohol extracts were evaluated on spectrophotometer \"Specord 40\" (Analytik Jena AG, Germany). \u0000Results. The dominant flavonoid substance, pinocembrin, was detected. This compound in chloroform-ethanol (4:1) solvent system had blue fluorescence at 365 nm. During the development of the chromatogram with an alkaline solution of diazobenzene sulphonic acid, a light green stain (pinoсembrin) was detected practically at the level of the pinostrobin stain. It is reasonable to determine the diagnostic flavonoid pinocembrin of licorice herb using pinostrobin as the reference standard. The flavonoids pinocembrin and pinostrobin have similar spectral characteristics and are similar in chemical structure. A method has been developed for quantitative determination of the total flavonoids in terms of pinocembrin in water-ethanol extract of licorice herb (Glycyrrhiza glabra L.) using the differential spectrophotometry. The total flavonoid content in the licorice herb varies from 0.390.002% to 3.480.015% (in terms of pinocembrin).","PeriodicalId":183034,"journal":{"name":"Aspirantskiy Vestnik Povolzhiya","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132748256","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study involved 45 people aged from 20 to 35 years with enamel color A3 and darker on the Vita Classical scale arranged in chromatic order. Using the random sampling method, all patients were divided into 3 groups, 15 people in each group. The course of home whitening lasted for 14 days with the following administration of a course of remineralization therapy for 2 weeks. The presence of hypersensitivity was evaluated before the course of home teeth whitening, after 3 days, 7 days, 2 weeks and 1 month. \u0000Results. The study revealed the highest incidence of hyperesthesia during home teeth whitening in patients of the first group, who used a hydrogen peroxide content of 10%. Presumably, the high percentage of the occurrence of dental hyperesthesia of 2nd degree in patients of this group resulted from the use of hydrogen peroxide as a whitening component, which is a more aggressive agent, if compared to carbamide peroxide. \u0000Conclusion. Home teeth whitening using a system containing 22% carbamide peroxide eliminates the risk of tooth hyperesthesia, since the whitening gel is used in individual trays, carbamide peroxide is used as a whitening agent, and the introduction of amorphous calcium phosphate into the gel does not cause fluid movement in dentinal tubules, thereby not causing sensitivity of the hard tissues of the teeth.","PeriodicalId":183034,"journal":{"name":"Aspirantskiy Vestnik Povolzhiya","volume":"116 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2023-06-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133940344","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
