The aim of the study was to find variant of diode laser (λ = 810 nm) irradiation, which ensures elimination of unwanted microorganisms, including Rothia aeria, from dental healing abutments, and consequently accelerates process of wound healing in implantologically treated patients. The scope of the study included identification of the most contami...

The aim of the study was to optimise operating parameters of a diode laser (810 nm), that could be used to effectively disinfect very small, microbiologically contaminated spots on historical cellulosic objects from the Auschwitz-Birkenau State Museum, and thus limit unnecessary treatment of whole objects. The scope included: assessment of microbio...

PurposeThe aims of the study were to identify microorganisms, including those in the VBNC state, inhabiting porous surfaces in oral surgery offices and to assess the biocidal effectiveness and impact of 300 ppm vaporised hydrogen peroxide (VHP) for 20 min on decontaminated materials.Methods From the surfaces of textured armrests of dental chairs, p...

In the Auschwitz-Birkenau State Museum in Oświęcim, Poland (A-BSM) a new research has been started on the use of vaporised hydrogen peroxide (VHP) as a disinfecting agent. The aims of the study were: to identify microorganisms inhabiting historical cardboard using molecular methods (MALDI-TOF MS, 16S rRNA genes sequencing and next-generation sequen...

Introduction: At the Auschwitz-Birkenau State Museum (A-BSM) actions have been undertaken to effectively protect employees and minimise risk of SARS-CoV-2 coronavirus spreading from the beginning of the COVID-19 epidemic. Aim of the article: The aim was to present the actions, instructions and procedures introduced at the A-BSM to provide inform...

Accurate antimicrobial susceptibility testing (AST) of cefiderocol remains a diagnostic challenge, especially in infections caused by metallo-β-lactamase (MBL)-producing Klebsiella pneumoniae. While disk diffusion offers a cost-effective alternative to broth microdilution, it is highly sensitive to factors such as media composition and the presence...

The aim of this study was to test the biocidal effectiveness of the disinfection technique using 90 % ethanol in the form of mist on wall painting layers in the block with inventory number A-28 located in the A-BSM. Using the DNA sequencing and MALDI TOF methods, species of bacteria and fungi inhabiting the wall surfaces were identified. Then, 90 %...

Purpose The aim of the study was to evaluate the biocidal efficacy and determine the influence of 90% ethyl alcohol applied in the form of a mist on the surface of model and historical leather. Materials and methods The main object of the study were historical leather shoes from the collections of the Auschwitz-Birkenau State Museum (A-BSM) in Ośw...

Aim: the aim of the work was to present the changes occurring on the model and historical cotton surface of cotton resulting from disinfection with 90% ethanol mist. Materials and methods: Samples of historical materials consisted of fabric elements from suitcases stored in A-BSM. A mist of 90% ethanol was applied for 15 s at a distance of 16 cm fr...

The aim of this study was to assess the influence of a protective layer of polyvinyl alcohol on the degradation process of artificial leather based on cellulose nitrate. Samples of the artificial leather were obtained from a suitcase dating back to the first half of the 20th century, not considered a historical artifact. The analysis involved Fouri...

Aim: The aim of the study was to quantitatively assess the effectiveness of microneedle mesotherapy in reducing skin discoloration. The results were analyzed using the gray-level co-occurrence matrix (GLCM) method. Material and methods: The skin of the forearm (7 × 7 cm) of 12 women aged 29 to 68 was examined. Microneedle mesotherapy was perform...

Aim: The aim of this study was to demonstrate the effects of using a preparation containing kojic acid on skin hyperpigmentation using hyperspectral imaging, which enables a quantitative assessment of the effect of the preparation used on the reduction of skin discoloration. Materials and methods: Preliminary studies were carried out on 12 patients...

The aim of the study was to assess the biocidal effectiveness and the effect of 80% and 90% ethanol applied in the form of mist on the surface of textile materials from historical A-BSM objects. The microorganisms used for the tests, namely, Cladosporium cladosporioides, Aspergillus niger and Penicillium chrysogenum, were isolated from the surface...

Gingivitis is accompanied by microorganisms, including pathogens, which must be eliminated to speed up the treatment of inflammation. Laser irradiation may be one of the safe methods for reducing tissue contamination on the tooth surface. The aim of the study was the assessment of the tooth surface in patients with gingivitis after the use of a dio...

The aim of this study was an attempt to use hyperspectral imaging and hemispheric directional reflectance, supported by GLCM and quadtree decomposition methods, for non-invasive analysis of historical objects. The research was carried out to adjust the wavelength of laser light, which could be used for decontamination, to the characteristics of his...

The paper presents the optimization of diode laser irradiation of corroded dental implants in order to reduce the number of microorganisms associated peri-implantitis. The research included the identification of microorganisms on the surface of removed dental implants in patients with peri-implantitis and the assessment of the biocidal effectivenes...

Patients undergoing implant treatment are at risk of peri-implant bone loss, which is most often caused by the adverse effects of microorganisms, but there are few proven procedures for their reduction. The aim of the research was to identify the microorganisms inhabiting the composites used to close the screw access hole (SAH), compare them numeri...

The paper presents the optimisation of a safe diode laser irradiation process applied to the surface of titanium implants in order to reduce microbial numbers in the treatment of inflammation classified as periimplantitis. The study comprised isolation and identification of microorganisms inhabiting surfaces of dental implants, crowns, teeth and sa...

The aim of this paper was to study the effectiveness of a diode laser (LD) for removal of microorganisms isolated from porcelain and zirconia crown surfaces used in implantoprosthetics in order to minimize infections around dental implants. In order to optimize biocidal efficacy of the process (at the same time, avoiding increasing the surface roug...

Background: Orthodontic elastics are used in orthodontic treatment with fixed braces. The effect of class I elastics on changing gingiva temperature as a periodontal component was investigated. Methods: To evaluate the temperature changes, objective and automatic classifiers were used to determine the sensitivity and specificity of the measurement....
