Purpose Given the importance of health and food literacy in interpreting food labels and making informed dietary choices, this study aimed to evaluate health and self-perceived food literacy, as well as attitudes toward food-label reading, among adults in T & uuml;rkiye. Design/methodology/approach This cross-sectional study included adults aged 18-65 years in Istanbul, T & uuml;rkiye, recruited through online snowball sampling between November 20, 2023 and March 13, 2024. Food-label reading attitudes, self-perceived food literacy and health literacy were assessed using the Food Label Reading Attitude Scale (FLRAS), Self-Perceived Food Literacy Scale (SPFLS) and Turkish Health Literacy Scale-32 (THLS-32), respectively. Data were analyzed using descriptive, correlation, group comparison and multiple linear regression analyses. Findings A total of 595 participants were included. Mean FLRAS, SPFLS and THLS-32 scores were 69.3 +/- 17, 91.1 +/- 22.8 and 30.5 +/- 9.6, respectively. Significant positive correlations were observed between THLS-32 and SPFLS (r = 0.34), THLS-32 and FLRAS (r = 0.24), and SPFLS and FLRAS (r = 0.52) (all p-values < 0.001). Higher education, sufficient nutritional knowledge and SPFLS were independently associated with higher FLRAS. Female gender, THLS-32 and FLRAS scores were associated with SPFLS scores. Better self-rated health, sufficient nutritional knowledge and SPFLS scores were independently associated with THLS-32, whereas age was inversely associated. Findings support targeted strategies to improve food-label interpretation and public nutrition and health literacy. Research limitations/implications The findings cannot be generalized to the entire adult population of Istanbul or T & uuml;rkiye. Future studies should incorporate representative sampling and direct assessment of label comprehension. Healthy dietary choices and attitudes enable individuals to manage their health more effectively. According to the findings of this study, food label reading attitudes, perceived food literacy and health literacy positively and significantly influenced each other. For individuals to lead a healthier life, they need to understand their own health status, acquire detailed information about the foods they consume, and correctly interpret the concepts presented on food labels. Approaches aimed at enhancing these factors will contribute to the protection and improvement of public health. Practical implications The findings highlight the importance of integrating food-label education with broader food and health literacy initiatives. Practical interventions should focus not only on providing nutrition information but also on developing consumers' skills to interpret nutrient declarations, ingredient lists, serving sizes, and nutrition and health claims. Such interventions may be particularly beneficial for individuals with lower educational attainment, limited nutritional knowledge, lower self-perceived food literacy, and older adults. Social implications This study establishes a strong relationship between Label Reading Tendency and Healthy Food Perception, underscoring the fundamental role of label literacy in promoting public health. Demographic variances observed in label reading status indicate significant inequity in consumers' ability to access and use health information. The findings necessitate that public policies mandate targeted label literacy training aimed at mitigating these disparities, thereby strengthening healthy food perception and fostering informed consumption across all social segments.
Originality/value To the best of the authors' knowledge, this study is among the first to simultaneously examine these three constructs using validated instruments in the Turkish adult population.
Analysis of Orthodontic Treatment Requirements and Their Influence on Quality of Life and Self-Esteem Among Adults
(Galenos, 2026) Zeynep, Aslihan; Öz, Abdullah Alper; Özaydın, Özge
Objective: To evaluate the the association of orthodontic treatment need on oral health-related quality of life (OHRQoL) and self-esteem in adult patients seeking orthodontic care. Methods: A total of 110 adults were recruited for the study. Orthodontic treatment need was evaluated using the index of complexity, outcome and need (ICON). Patients with a score of 43 and above were classified as Group 1; those with a score below 43 were classified as Group 2. Oral health-related quality of life was evaluated using the Oral Health Impact Profile-14 (OHIP-14), and self-esteem was assessed using the rosenberg self-esteem scale (RSES). Statistical evaluation involved Spearman's rank correlation, Mann-Whitney U tests, and independent samples t-tests. Results:The mean OHIP-14 score was higher in Group 1 (12.63 +/- 7.46) than in Group 2 (10.61 +/- 7.46). However, this difference was not statistically significant (p=0.176). Mean RSES scores did not differ significantly between the groups (p=0.741). A slight but meaningful positive correlation emerged between ICON and OHIP-14 scores, indicating that as orthodontic treatment need increased, OHRQoL tended to decrease. No significant correlation was observed between ICON and RSES. Additionally, gender was not significantly associated with either OHIP-14 or RSES scores. Conclusion:The analysis revealed that increased need for orthodontic treatment is associated with a slight worsening of OHRQoL but does not significantly affect self-esteem in adult subjects.
Effect of Solvent Use on Dentinal Integrity and Filling Removal During Endodontic Retreatment: A Micro-Computed Tomography Study
(2026) Zümrütel, Pelin; Haznedaroğlu, Faruk; Keleş, Ali; Basmacı, Gülsüm Kutlu
Introduction: This study evaluated, using micro-computed tomography (micro-CT), whether solvent use during endodontic retreatment influences dentinal defect formation and the removal of filling material compared with mechanical retreatment alone. Materials and methods: Twenty extracted human mandibular molars were prepared and obturated using standardized protocols and randomly allocated to solvent-assisted retreatment or retreatment without solvent (n=10 per group). Micro-CT scans were obtained before treatment, after obturation, and after retreatment at a voxel size of 13.68 μm. Dentinal defects were assessed using axial images, and residual filling-material volume was measured three-dimensionally in the apical, middle, and coronal thirds. Between-group comparisons were performed using the Welch independent-samples t-test or Mann-Whitney U test, as appropriate. Within-group comparisons were performed using the Friedman test. Results: No dentinal defects were detected in any specimen (0/20). However, the exact 95% confidence interval indicated that a low-incidence effect could not be excluded. Residual filling material was detected in all canals after retreatment. No significant differences were observed between the solvent-assisted and non-solvent groups in residual filling-material volume at any canal third after adjustment for multiple comparisons (all adjusted P>0.05). Conclusions: Under the conditions of this in vitro study, solvent use did not significantly improve filling-material removal compared with mechanical retreatment alone. No dentinal defects were detected in either group; however, the exploratory nature and limited sample size of the dentinal-defect analysis preclude excluding a low-incidence effect.
Barodontalgia and Flight Safety: A Critical Narrative Review of Pressure Physiology, Acute Pain, and Human Factors
(İstanbul University Press, 2026) Gürler, Esra Bihter
Barodontalgia is dental or orofacial pain brought on by a change in barometric pressure, and it usually points to an underlying dental or maxillofacial problem rather than standing as a disease on its own. This narrative review looks at the condition through five lenses: pressure physiology, clinical presentation, epidemiology, occupational stress, and human factors relevant to flight safety. A literature search was conducted using PubMed/MEDLINE, Web of Science, Scopus, Google Scholar, and DergiPark between 22 April and 7 June 2026. One systematic review covering 4,894 aircrew members and divers reported an overall experience rate of 8.2%, with divers at 9.8% and aircrew at 5.8%. Divers may be more exposed simply because pressure changes more rapidly over a short vertical distance underwater and because descent-ascent cycles occur more often, though differences in study design across the diving and aviation literature make a direct comparison difficult. A Turkish pilot survey found that 81% of those who had experienced barodontalgia placed the pain below 2,000 ft. That is a striking figure, but it comes from self-report: it points to a plausible overlap with low-altitude, pressure-changing flight segments without actually confirming the flight phase or an operational safety effect. Bruxism, occupational stress, and barodontalgia appear together in the literature, but the association is observational and says nothing about causality. General pain research backs the idea that pain can pull attention away from a task, yet no study has measured pilot performance during an actual barodontalgia episode. Taken as a whole, the evidence makes barodontalgia a biologically credible and operationally worth-watching problem, potentially preventable in principle, even if its real performance cost has not yet been quantified
Honoring Paris Pişmiş' Legacy: Uniform Astrophysical Properties of 14 Understudied Clusters from Gaia DR3
(IOP Publishing, 2026) Koç, Seliz; Akbaba, Furkan; Plevne, Olcay; Alan, Neslihan
Open clusters are fundamental tracers of the chemical and dynamical evolution of the Galactic disc. This study presents a systematic characterisation of 14 understudied open clusters from the Pismis catalog, selected as those for which the Gaia DR3 data support a well-defined stellar sequence, and spanning a wide range of ages and distances. Utilizing high-precision Gaia DR3 data, we aim to provide a high-fidelity modernisation of these historical discoveries while testing the consistency of our analytical framework across diverse stellar populations. Membership probabilities were determined via the unsupervised UPMASK algorithm using Gaia DR3 astrometric data (positions, proper motions, and parallax). To ensure high sample purity, the member samples entering the isochrone fits were restricted to P >= 0.90, with all subsequent astrophysical parameters calculated through membership-weighted likelihoods. Fundamental properties-including age, distance, reddening, and metallicity-were derived using a Bayesian Nested Sampling approach to isochrone fitting, a methodology chosen for its robustness in navigating the parameter degeneracies typical of dense Galactic fields. The 14 systems exhibit a broad distribution of properties, with ages ranging approximately 11 Myr to 1.5 Gyr and distances spanning approximately 690 to 5445 pc. These refined and uniform parameters reconcile historical observations with the precision era of modern astrophysics, providing an internally homogeneous baseline for systems that large-scale automated surveys recover only partially. A direct cross-match against widely used automated catalogs shows that they typically contain only about a third of the members identified here, and substantially less in the most crowded fields, underscoring the value of cluster-specific analysis. This work contributes to a more complete census of the Galactic disc and sets out a reproducible, per-cluster reliability assessment that can be applied to the many comparable low-latitude systems that remain to be characterised.
