Objective: To examine the effects of six whitening mouthwashes on tooth color and immediate bond strength to the enamel., Materials and Methods: Human incisors were divided into seven groups (n = 10) according to mouthwashes (R.O.C.S Black Edition White, Splat White Plus, Colgate Plax White Charcoal, Signal White Now, Listerine Advanced White, Colgate Optic White, and distilled water). After the initial color measurements, the teeth were exposed to mouthwash for 4 weeks. Then, the color measurements were repeated. Then, cylindrical composite resin blocks were immediately applied to the enamel surfaces and subjected to shear bond strength tests. Data were analyzed using Kruskal-Wallis and Bonferroni tests (α = 0.05)., Results: Δ𝑏, Δ𝐿, and ΔE 00 values did not present significant differences among the groups. Significant differences among the groups were determined for Δ𝑎 and ΔWI D values (p < 0.05). R.O.C.S Black Edition White and Splat White Plus produced clinically acceptable color changes. Signal White Now, Splat White Plus, and Listerine Advanced White created acceptable whiteness changes. The mouthwashes did not statistically affect the bond strength compared to the distilled water (p > 0.05)., Conclusions: Whitening mouthwash containing blue covarine revealed more acceptable color and whitening changes. Mouthwash containing charcoal led to the lowest enamel bond strength values., Clinical Significance: The content of whitening mouthwashes affected the degree of tooth whitening and shear bond strength to enamel., (© 2024 The Author(s).

Retirees face numerous challenges, particularly in countries with lower socio-economic conditions. Perceived social isolation and happiness levels are seen as significant factors that significantly affect the quality of life in old age. Perceived social happiness levels can disrupt the quality of life in old age and contribute to mental disorders. Recent studies on leisure have suggested a direct impact of individuals' leisure attitudes on happiness. In this context, leisure nostalgia stands out in the relationship between leisure attitude and happiness levels among retirees. In this study, structural equation modeling (SEM) was employed to examine the relationship between leisure attitude, leisure nostalgia, and happiness levels in a sample of 210 retirees. The findings revealed that leisure nostalgia fully mediated the relationship between leisure attitude and happiness. It was concluded that previous experiences significantly shape retirement, and leisure attitude offers valuable opportunities for enhancing happiness through effective leisure utilization., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2024 Onal, Bedir, Turan, Mavibas, Savaş and Yasarturk.)

Objective: The aim of this study was to investigate whether urinary glycosaminoglycans (GAG) levels reflect clinical status in men with lower urinary tract symptoms and if they could be used as a marker in management of overactive bladder (OAB)., Methods: A total of 34 patients were recruited who were admitted with LUTS and diagnosed as having clinically bladder outlet obstruction (BOO) due to prostate enlargement. These newly diagnosed, never treated patients underwent routine investigation, consisting of history, physical examination, PSA, ultrasound, uroflowmetry, assessment of symptoms scored by both International Prostate Symptom Score (IPSS) and Marmara- Overactive Bladder Questionnaire (M-OBQ). The patients were divided into two groups as those with an initial M-OBQ score < 12 (group 1) and ≥ 13 (group 2). Alfa blocker was initiated in eligible patients. Further evaluations included prostate volume measurement, pre- and post-treatment urinary GAG levels, IPSS and M-QAOB values and maximum urine flow rate (Qmax)., Results: Before treatment, urinary GAG level was 21.5 mg/gCr (6.1-45.5) in Group 1, and 23.35 mg/gCr (15.6-32.6) in Group 2 (p =0.845). After the treatment, the GAG level in Group 1 and Group 2 were found to be 19.8 mg/gCr (7.4-70.5) and 18 (7.6- 41.7), respectively (p = 0.511). No difference in GAG levels was found in subgroup analysis for patients with or without OAB., Conclusions: In recent years, there have been many studies investigating the relationship between LUTS and urinary markers. However, in our prospective study, no relationship was found between pre- and post- treatment urinary GAG levels in patients with LUTS with or without OAB.
