Objectives: The aim of the present in vitro study was the evaluation of two toothpastes (Sensodyne Pronamel and Biorepair Plus on repairing enamel erosion produced by a soft drink (Coca Cola), using Atomic Force Microscopy (AFM).
Methods: Fifty extracted human central incisors free of caries were selected and divided in a treatment and a control half; they were kept in artificial saliva during whole experimentation. The treatment halves were divided into five groups; group 1: demineralization with soft drink; group 2: demineralization with soft drink + Pronamel; group 3: demineralization with soft drink + Biorepair Plus; group 4: intact enamel + Pronamel; group 5: intact enamel + Biorepair Plus. Specimen demineralization was carried on in 4 intervals of 2 min. In groups 2, 3, 4, and 5 the toothpastes were applied for 3 min at 0, 8, 24 and 36 h. The surface of each specimen was imaged by AFM and R(rms), root-mean-square roughness, and Maximum Depth of the cavities were registered.
Results: Amongst treatment specimens of groups 1, 2, and 3 a statistically significant difference (P<0.01) in R(rms) and Maximum Depth values was registered: the toothpastes reduced enamel demineralization. No statistical differences in R(rms) values were registered between the two toothpastes.
Conclusions: The toothpastes tested (Pronamel and BioRepair Plus) offer a degree of protection from erosive drinks.

École de nutrition, Faculté des sciences de l'agriculture et de l'alimentation (FSAA), Université Laval, 2440, boulevard Hochelaga, Québec, Québec, G1V 0A6, Canada.
Background: A better understanding of correlates of sugary drink consumption is essential to inform public health interventions. This study examined differences in perceived healthiness of sugary drinks and related social norms between countries, over time, and sociodemographic groups and associations with sugary drink intake.
Methods: This study used annual cross-sectional data from the International Food Policy Study from 2018 to 2021 in Australia, Canada, the United Kingdom, the United States, and Mexico.
Comparative Evaluation of Surface Roughness and Color Stability of Polyetheretherketone with Conventional Interim Prosthetic Materials: An Study.

Department of Prosthodontics, Government Dental College, Kozhikode, Kerala, India, Orcid: https://orcid.org/0000-0003-1456-3851.
Aim: The aim of this study was to compare the surface roughness and color stability of polyetheretherketone (PEEK) with those of conventional interim prosthetic materials like polymethylmethacrylate, bis-acrylic composite, and rubberized diurethane dimethacrylate, following immersion in solutions of varying pH value.
Materials And Methods: A total of 320 circular discs with 10 mm diameter and 2 mm height were divided based on the fabrication ( = 80)-group A: polymethylmethacrylate; group B: bis-acrylic composite; group R: rubberized diurethane; and group P: hot-pressed PEEK-and were subjected to baseline measurement of roughness ( = 40) and color ( = 40) using 3D profilometer and UV-Vis spectrophotometer, respectively. Later, 10 samples from each group were immersed in distilled water, black coffee, green tea, and Pepsi, respectively, for 120 days, and measurements of roughness and color were repeated.
Interrelation Between BMI, Dietary Habits, Self-Rated Health, and Body Image Perception Among Korean Adolescents: The Korea Youth Risk Behavior Web-Based Survey (2022).

Department of Sports Rehabilitation, Jaeneung University, Incheon 22573, Republic of Korea.
Background/objectives: Adolescent obesity is highly likely to lead to adult obesity and is associated with dietary habits, subjective health, and body image perception. This study aimed to analyze the relationships between BMI, dietary habits, subjective health perception, and body image perception among Korean adolescents using data from the 18th Korea Youth Risk Behavior Survey conducted in 2022 to explore strategies for reducing adolescent obesity rates.
Methods: Data from 50,427 participants were analyzed, including BMI, seven lifestyle factors (intake frequencies of water, milk, fruit, soft drinks, vegetables, breakfast, and late-night snacks), and responses to one item each for subjective health perception and body image perception.

Importance: Patients with urgency urinary incontinence are often recommended to avoid bladder irritants, but there is a lack of evidence for this.
Objective: The aim of the study was to compare consumption of purported bladder irritants between women with and without urgency urinary incontinence.
Study Design: We performed a case-control study of nonpregnant females aged ≥20 years using the National Health and Nutrition Examination Survey, 2007-2020.
