Objective:To determine quantitatively the amount of demineralization and the ability of commercially available products and an experimental cream to inhibit or reverse orthodontic related demineralization.Methods:A total of 20 patients who were 25-35 years old and having orthodontic treatment for 6-8 months were chosen.Caries risk assessments were done for each patient and ones with moderate risk were included.Patients with fixed orthodontic appliances were divided into 4 groups (5 patients each) including one control and 3 study groups.All patients used same toothpaste 2 times a day during the 3 weeks study period.Additional to the toothpaste first study group used MI Paste Plus (GC,Tokyo,Japan),second study group used Remin Pro (Voco,Cuxhaven,Germany) and third group used an experimental rcmineralizing cream per day for 3 weeks.Maxillary central and lateral incisors of each patient were examined by FluoreCam (Daraza Therametric Technologies,USA) device.The examinations were performed at baseline and at the end of 1 st,2nd and 3rd weeks.Results:According to the FluoreCam measurements the control group showed significant amount of demineralization at the end of 3 weeks,moreover the amount of demineralization has gradually increased in time.At the end of the study all 3 study groups showed significant amount of remineralization and the amount of remineralization for all the 3 study groups has gradually increased in time.However the amount of remineralization for 3rd study group was lesser than the 1 st and 2nd study groups.The remineralization amounts for the 1 st and 2nd study groups were determined to be identical.Conclusions:This study demonstrated that demineralization is measurable around orthodontic brackets and the demineralization can be completely inhibited and/or reversed by the use of commercially available remineralization products.

Background: The aim of the study was to test the validity and reliability of the Perceived Future Decent Work Securement Scale for Turkish nursing students. Methods: A cross-sectional, methodological study design was used. The study was carried out at three nursing undergraduate programs in Turkey during the academic year of 2020–2021 with 336 senior nursing students. Language validity and content validity analyses were performed for the scale adaptation, followed by confirmatory factor analysis (CFA) for construct validity. The reliability of the scale was determined using the test-retest and Cronbach's alpha internal consistency coefficient. Results: The scale-content validity index score was 0.988. In CFA, all goodness-of-fit indices verified the acceptable fit of the model; its root mean square error of approximation was 0.076; the normed fit index was 0.909; the standardized mean square residual was 0.097; the relative fit index was 0.881; the goodness-of-fit index was 0.915; the adjusted goodness-of-fit index was 0.872 and χ2/df = 2.932. The overall reliability was α = 0.86. The item-total correlations of the scale were above the acceptable level, and the test-retest analysis had a high correlation. The access to healthcare (14.68, SD 3.53) obtained the highest average score, and the adequate compensation (8.52, SD 3.76) was the lowest rated by the senior nursing students. Conclusion The Perceived Future Decent Work Securement Scale is a valid and reliable scale to assess nursing students' future decent work securement.

Objective To determine quantitatively the amount of demineralization and the ability of commercially available products and an experimental cream to inhibit or reverse orthodontic related demineralization. Methods A total of 20 patients who were 25–35 years old and having orthodontic treatment for 6–8 months were chosen. Caries risk assessments were done for each patient and ones with “moderate risk” were included. Patients with fixed orthodontic appliances were divided into 4 groups (5 patients each) including one control and 3 study groups. All patients used same toothpaste 2 times a day during the 3 weeks study period. Additional to the toothpaste first study group used MI Paste Plus (GC, Tokyo, Japan), second study group used Remin Pro (Voco, Cuxhaven, Germany) and third group used an experimental remineralizing cream per day for 3 weeks. Maxillary central and lateral incisors of each patient were examined by FluoreCam (Daraza Therametric Technologies, USA) device. The examinations were performed at baseline and at the end of 1st, 2nd and 3rd weeks. Results According to the FluoreCam measurements the control group showed significant amount of demineralization at the end of 3 weeks, moreover the amount of demineralization has gradually increased in time. At the end of the study all 3 study groups showed significant amount of remineralization and the amount of remineralization for all the 3 study groups has gradually increased in time. However the amount of remineralization for 3rd study group was lesser than the 1st and 2nd study groups. The remineralization amounts for the 1st and 2nd study groups were determined to be identical. Conclusions This study demonstrated that demineralization is measurable around orthodontic brackets and the demineralization can be completely inhibited and/or reversed by the use of commercially available remineralization products.
