“…The bleaching effect of a 3.5% hydrogen peroxide solution containing titanium dioxide depends on the light properties, and the wavelength range of the 405nm diode laser corresponds to the absorbance of the agent. The 405-nm diode laser have recently been developed in After mixing A with B, the concentration of hydrogen peroxide was 3.5% and the pH of the solution was 6.0 industry and tested experimentally for the ablation of soft tissue [11][12][13].…”

Abstract:A low-concentration hydrogen peroxide solution containing titanium dioxide as a photocatalyst has attracted attention as a safe office bleaching agent. In this study, the influence of different kinds of light on the bleaching effect of this agent was examined. The bleaching agent was applied to hematoporphyrinstained paper strips that were then irradiated with a 405-nm diode laser (800 mW/cm 2 ), a halogen lamp (720 mW/cm 2 ), or an LED (835 mW/cm 2 ) for 5 minutes. The color was measured spectrophotometrically before treatment and every 30 seconds thereafter, and the effects of bleaching on the strip were assessed using the CIE 1976 L * a * b * color coordinate system. Of the three different irradiation conditions, 405-nm laser irradiation gave the strongest bleaching effect with 3.5% hydrogen peroxide containing titanium dioxide. The laser provides strong irradiance at 405 nm, which corresponds to the absorption range of the bleaching agent, and consequently the largest effect was obtained.

“…При сравнительном гистологическом исследовании препаратов гортани курильщиков с некурящими приводятся следующие отличительные признаки: 1) более толстый эпителий благодаря усиленной кератинизации и гиперплазии его; 2) большая степень круглоклеточной инфильтрации; 3) несколько больший отек собственного слоя слизистой оболочки; 4) выраженная метаплазия вестибулярных складок и подскладочного эпителия слизистой оболочки нижнего отдела гортани. В результате длительного действия перечисленных (вредных) факторов нарушается трофика тканей, изменяется их реактивность, развивается дистрофический процесс [5][6][7][8].…”

Chronic edematous-polypous laryngitis (Reinke – Gayek disease) as a cause of hoarseness. Personalized approach to the surgical treatment

Introduction. Chronic edematous-polypous laryngitis, Reinke – Gayek’s edema accounts for 5.5% of all benign diseases of the vocal folds. Surgical treatment of Reinke – Gayek disease consists in removing excess mucosa, or “stripping” – tearing off a strip of mucosa with forceps from the vocal fold. The principle of laryngeal surgery is to preserve the structures of the vocal fold, to obtain flexible vibration of the muscular-membranous part and the mucous membrane of the vocal fold.Purpose. Improving the effectiveness of the treatment of patients with Reinke – Hayek edema by developing sparing methods of surgical treatment using a carbon dioxide laser. To develop criteria for choosing a method of sparing surgical treatment of Reinke – Hayek edema using a carbon dioxide laser, depending on the type of edema according to the Yonekawa classification.Materials and methods. 80 patients with Reinke – Gayek’s disease, 59 women and 21 men, from 29 to 77 years old, divided into two subgroups, and a control group were treated. Preoperative examination included endoscopic examination, laryngostroboscopy. The type was determined according to the H. Yonekawa classification. In type II, subgroup 1 – aspiration technique, n = 30. In type III, subgroup 2 – M-shaped technique, n = 30. Control group, it includes patients with type II and III edema, resection technique, n = 20.Results. Patients in the preoperative period were surveyed with the SF-36 Health Status Survey questionnaire, the dysphonia severity index (DSI), as well as the time of maximum phonation. In the postoperative period, they were examined, 1 month after the operation and 6 months after the operation. There is an increase in indicators, an increase in the time of maximum phonation, an increase in SF-36 scores.Conclusion. The use of this technique made it possible to significantly accelerate the recovery of the voice, reduce the time spent in the hospital, minimally damaging the structure of the mucous membrane of the vocal folds.

“…High-power lasers are widely used for measurements and are particularly important in health research and clinical diagnostics. [1][2][3][4][5][6] These lasers have significant potential applications in military, industrial production, and other areas of daily life. [7,8] The development of laser systems depends on the manufacturing improvement of optical devices, such as lenses, mirrors, and polarizers.…”

The angular resolutions of the phase-shifted Rugate thin-film filters, the ultra-narrow bandpass filters, and a cutoff filter-combination device are discussed, and the electric field distributions of the filters are compared. The results show that the three transmitting multi-layer thin-film filters can realize the same angular resolution, but the electric field in the cutoff filter-combination device is the lowest. Because a lower electric-field distribution corresponds to a higher laser-induced damage threshold of the thin films, the cutoff filter-combination device may replace the traditional spatial filters in high power laser systems.
